Jesse, Jesse, thank you very much for the efforts. I don't know what goals you have, but I can certainly see your passion as a software development educator and I definitely can see your talent for it. Great job, keep up the good work.
Hello Jessie, i am from Germany and my English is very bad, but i can understand your video because you are using simple words. This ist great. Thank you for your good help. It helps me a lot
Hi, I've been coding web applications for the last 3 years now. Although your video was posted a long time ago it really helped me out to grasp the basic concept of WCF. The way you explain stuff is awesome... You're awesome ! Thank you so much for this video and probably many others that i will check out from your channel :-)
Hi Jesse. I'm Pole and I have started learning about WCF in polish from polish non-free tutorials. But your type of explaination its very easy to learn. I enjoyed your video very much.
Jesse, man...thanks a ton for the video! I am now going to be able to take this and change so many apps that I have written to be more efficient when communicating over the web (before I used to write my own web services)...WCF is so much more powerful. You did an excellent job at explaining how it works! Thanks again for everything!!
i guess im randomly asking but does anybody know of a way to log back into an Instagram account..? I was dumb lost my password. I would appreciate any tips you can give me
Hi Jessie, First of all I would like to thank you so much for spending a lot of time to make this tutorial. I was searching such this kind of tutorial for a long time and finally I find it. The way you explained, it is just awesome. Thanks a lot.
Thx for the MySQL and WCF info. Thorough and comfortable pace. Plan to use WCF for a SharePoint to MySQL data POC. Keep up the good work. I will certainly list you in my credits.
Jessie, I also have to comment on here (what I usually almost never do), your tuts are great man. You take your time and explain everything (sometimes it's a lot too slow for my taste, but that's why we have the fast forward function ;-). Anyways, I'm doing a Business Informatics Bachelor's degree in distance study and if our teacher would offer content half as good as yours life would be much easier. Your name is always the first I tell my colleagues to when they ask me where to find good tutorials (2nd would be Mr. Jamie King). I was the only one from the whole class who passed the C# exam at the first attempt! Many thanks man & keep up the good work! Greetings from Austria
+Jesse Dietrichson I just discovered your tutorials. You speak clearly, and you aren't just sliding a mouse in a point and click sequence that you learned from a rumor that gets the job done. You actually planned your presentation.
Great video, overall you explained really well for someone who never used WFC before, but I have a few qestions: - At 41:00 which of the options is more effective in terms of performance? - Why did you use Mysql instead of SQL Server since is way more complicated to integrate Mysql with visual studio? Is there a reason beyond your preference for Mysql? - I forgot my other question but ill post it as soon as i remember :)
would be great teach how insert/edit/delete data, Im following another tutorials for this but they dont use the database as an object for do it, you did it really simple
awesome work, kinda new concept to me but not that hard tho, really appreciate your videos, and yeah that will save alot of time specially for people that dislike sockets and packet system, thanks for taking time to make those videos :)
I think your video is pretty great man(I'm only 13 minutes in) . But I think it would be a better idea to show a wcf service in the beginning play around with it, so we have an idea what we are building towards, and then dive into how it's build and what it does in relation to what you showed us in the beginning. But you are explaining all the concepts really well, so I am really pretty happy! Thanks, bro!
Jesse, Thanks for the video. It enhances the traditional training sources. I have a question about the ado.net references. The SQL table is called "Product". In the code, you reference the table as "database.products". Why does the code reference to the table add "s" to the name? I see in the database designer that there is a class that appears to reference the Product table and the class name is products. Why doesn't the code call the table name by its actual name? I would expect the reference to be database.product. What happens if you have two tables, one named "Product" and one named "Products"?
when importing a database to visual studio using this method, the engine automatically Pluralizes the table names in order to make it linguistically easier. it turns each table into what VS calls DbSet which is a kind of List. and as you may know its common to name lists in plural. for example: if i have a Product class, i would define that list - List Products. so this is what ADO.net does basically.
Awesome, very simple very clear ! I hope you have a solution to my problem. A company has 50 web services, each service holds the data structure for the database at the moment. So changing the structure requires adjustments in some, if not all services. Preferred would be to have one place to change the database structure and from there communicate with the web services and leave them untouched. How would you approach that?
Superb lesson, you're a great teacher. I have built a service, service host console app & WPF client app. Everything works great in the Visual Studio environment. When I try to run my console host app from the debug .exe the app runs but the service doesn't seem to run....
Wonderful!!! You have a new subscriber! Could you make a video explaining how to deal with transfering more complicated data (tables linked with foreign keys, for example), how would you then design the data shared classes? Thanks in advance!
Unexpected exception occured when generating the model. Exception message: "StrongTypingException: The value for column 'IsPrimaryKey' in table 'TableDetails' is DBNull"
Hey Jesse, I searched a long time for a tutorial like this, thanks man. My only problem is, that I want to write an application where the user can select the server at runtime. Can you tell me a solution?
When i run the project I get exception in ProductService.Program.the exception comes on the line where You Create the ServiceHost Object. The Exception is Argument exception and additional information is "ServiceHost only supports class service types.". I've followed everything as you did.
Hey, neat tutorial. I'm surprised you start with ChannelFactory rather than the more generic and potentially more nooby friendly Proxy that Visual Studio can create for you.
+Jon Edwards Furthermore, there is a difference between a proxy implementation and using Channel Factories: www.codeproject.com/Tips/558163/Difference-between-Proxy-and-Channel-Factory-in-WC
wow, haha dude ....ive learnt c# all through via your vids and this stuff just excites me with all the stuff i can do now...realy cool... bythe way with the new windows 8 apps...can i do this stuff...i heard they use different classes and api's...please reply
Yes you can. However it is a lot easier if you use a metadata exchange. Windows 8 apps cant use app.config files so you would have to set all the info in code. Instead of doing that if you use a metadata exchange you can just right click and select add service reference and its all done for you. Check out the video I made on metadata exchange and you'll be able to do it. If you need any help let me know and I could make a video on it.
thank you so much...and can i ask....ever since you touched visual studio and started with "variables"...haha....how long has it been....did you have challanges ie getting bored..and did you learn this in school..or by yourself like me
I'm 20 years old and I started programming probably about 6 - 7 years ago. I've been teaching myself programming up until I starting going to college. I didn't really ever get bored of programming because there was just so much to learn that I was also interested. However I did have a lot of challenges. When I started learning programming I was like 13ish and the only way I could learn was from reading books. Most programming books are not designed for a 13 year old and It was really hard for me to understand. I was trying to learn concepts like WCF and I could just not understand it. In order for me to understand it I had to read about the same topic multiple times from different authors to try to grasp what the author was talking about. Up until I started going to college, I programmed everyday of my life and read every day of my life. I thought about programming literally 24/7. I was so addicted to learning programming that I literally skipped out on going on family vacations to stay home and read. So that's basically where we are now. The funny thing about this all is after all of this work I have done, and all of this learning, I can't even get an internship. Microsoft doesn't even reply to my internship requests. Anyway that's a little about me, how about you? When did you start programming?
Jesse Dietrichson wow, ok i always had intrest in this thing but i never even knew there was something like programing by 11..by 15 i could do alot of stuff that most pple didnt know on a pc...but there was no acces to programing books ANYWHERE...i came to know about vb from my dad at 17...then i looked for others..and finnaly landed on c#...all i used was youtube vids and they all mixed me up since i was so excited...now im #18...learning step by step...i found my first harcopy book when i went to uni this yr...and its cool...am sure you are so comfortable ryt now with programing...i so envy you...lol
things to do with making a computer always just makes me blow up...i stay on my laptop basically 8 hrs a day and sleep for 4 hrs to go to school in the morning ....i dream of apps that i CAN MAKE IN CLASS AND Scribble SO MAY THING S ON MY BOOKS...MY CLASSES ARE EASY SO Its-easy to catch up....i basically have books and i cant concentrate on anything else...i don't live with ny parents so its so easy for me to do what i want ever...right now im planning on a certain app*...and i watched WWDC live today (2 hrs ago)..it was so ow-some and i so wish id be an iPhone developer hahaa....anyway that's my life...when i finally understand wcf completely, then do client-server database connections properly and know how to make my laptop a sever for apps i make ...ill be so grateful about that.,...actually i think you should Finnish this video completely with the app then send me the exe..haha...sooo...im still learning...ive been coding 4 1.5yrs i gues...im starting to be comfortable ....sometimess its boring to read all this stuff and not realy have somewhere to apply...just conceppts..easy to understand...
Hey Jesse, awesome video, do you have away to setup a WCF service not with IIS integrated with Xamarin, ive created a app which uses ORM and ADO to create and store my database locally, but would like to create a WCF service to read and write data to my app. Any assistance would be awesome. Cheers
The ServiceContract "IS" the interface. Everything you want your service to expose should be lined up there. By adding another Interface (Your DLL i.e.) you're just introducing a dependency to a client. Why as a Service developer would you want your clients be dependent on an outside interface?
hi... is this topic still on ? I have a question, besides linq and the foreach class, what other options do I have to retrieve data from the ADO-net model ? How do I join table infirmation (foreign keys) for example ? thanks
I have done every step one in one like in Your Video, but I have an Exception An unhandled exception of type 'System.InvalidOperationException' occurred in System.ServiceModel.dll Additional information: The HttpGetEnabled property of ServiceMetadataBehavior is set to true and the HttpGetUrl property is a relative address, but there is no http base address. Either supply an http base address or set HttpGetUrl to an absolute address. Can You Help me? I can not understand why I have this exception
Hi, I'm doing now my final progrming project, and this video is very helping me. I just didn't get the part that you separate the instrafaces product from the rest of the code. The interface is only for the client side? or it also for the server? Because in my project I'm doing interfaces for both of them.
What do you mean you're doing interfaces for both client and server. Are you doing a duplex server so you have the service contract, and the callback contract on the client? By doing it that way it allows you to not only call the service but also have the service make calls to clients. The reason I made a separate project for the interface(service contract) is because both the client and service need to see it. I don't want to make two separate copies because that isn't efficient, and when I make changes in one, I would have to do it in the other.
Jesse Dietrichson thanks for your quick response. I was a little bit confusing at first(becouse I'm doing the project with windows form and I didn't understant how wotk with it and WCF together). However, now I'm understaing why you separate the instrafaces. Thank you again!
All this time I was trying to build WCF services with VS 2015 express, when I should have installed VS 2015 community. I'm all set now, although I can't manage to make my services work through public network.
OMG that took forever to figure out granted I am not as advanced in visual studio as you are. You never mention placing a reference to System.Runtime.Serialization. Any way I figured it out after redoing everything.
Usually on c#do like this Interface temp= new implementation() but when you define the channel factory you define like interface temp = new interface () how you link to the implementation? you cant apply method on the interface, that strange
Hey what if i want to list all of the elements from ddatabase not only first it's like Employee matchingProduct = database.Employees.First(p => p.Title == imie); and i want not only first element but all of the element wchich include in this condition????
Use .Where instead. This will return an IEnumerable of all matching entities e.g. IEnumerable matchingEmployees = database.Employees.Where(p => p.Title == imie); You could also return it as a list with .ToList() e.g. List matchingEmployees = database.Employees.Where(p => p.Title == imie).ToList();
Jesse at 26.11 you resolve the issue with IWCFProductService but I am not getting that option instead I get error CS0535 that says does not implement interface Member Please Help me
Jesse, I'm using VS 2013 express and MySQL connection is not listed. I can read the adventure works database thru MySQL Workbench. I'm running Win 8.1 and I selected the "developers" option when I installed MySQL. I had tried to due a "custom" install of MySQL selection the 3 packages you told us in the first video but I keep on having a problem with it not finding the "my.ini" file. When I selected "developers' option the installation seem to go fine. Any suggestions on how to get VS 2013 to see the MySQL server?
Nevermind, i fix it, i just clean all the garbage and leave just the connection points (i was doing the tutorial without using EntityFramework) Anyway, excelent tutorial, you should do more of this, maybie one about socket? that would be awesome Have a nice Day, and an Excelent Morning!! (y) (y)
I just want to THANK YOU from the bottom of my heart, you have no idea how you have helped me. Thank you once again
I'm glad I could help.
Same feeling brother. Thank You so much!

I'm happy you liked it.
Thanks, that was a good fist step in uses and understanding a WCF Service.Thanks...
This is the coolest video i ever seen ! thank you !
Great video!! Thanks for sharing.
👌👌👌👌 so glad I found you man. Your videos are on point!
This is the 2nd video? Link to the first?
Great tut. Thanks. Well explained and thorough.
Really cool tutorial. Thanks for doing it.
There is not a lot of them, and you're explaining it well :)
Can't wait to see the next :)
I'm glad I could help!
Hey Jessie, Thanks for the great introduction ! Very helpful. Suggestion to the viewers, watch it @ 1.25 speed. The video is great!
thanks bro. much easier than to read boring manual ;)
Thank You for making me this understand crystal clear. Even in my University Sir AMM was not able to explain me after 3 months of lectures and Labs

Thank you very much, i came here to understanding what is WCF =)
Good explanation.. Thanks
Great Video, Many thanks. the video was great and with a good speed . Many thanks.
off-topic: let's count "basically" word
on-topic: awesome tutorial, thank you!
Thank you. Really helped me to understand WCF
you can actually add that First() on your Linq query and return the product object directly from the Linq query
Awesome tutorial bro! Thanks a bunch! :D
Thanks !
Nice Stuff
Thank you very much for the nice tutorial.
Hi Jeese, thank you very much for this video, this was really helpful!
Hey Jesse Dietrichson - Thank you for that Tutorial! Great Job :)
you made my day!!! thank you for the lesson!
Thank u very much for this amazing video tutorial .
wow good video. thanks! do you have a video about WCF when client and server not found in the same solution?
Jesse,
Thanks for the video. It enhances the traditional training sources. I have a question about the ado.net references. The SQL table is called "Product".

I hope you have a solution to my problem.
A company has 50 web services, each service holds the data structure for the database at the moment. So changing the structure requires adjustments in some, if not all services. Preferred would be to have one place to change the database structure and from there communicate with the web services and leave them untouched. How would you approach that?

Have one question - I made everything as you show. Now it throw an EndpointNotFoundException, what I did wrong?
Did you open the host in the server?
Cheers up!

Bug in MySQL. Easiest solution is to add optimizer_switch = 'derived_merge=OFF' to the end of your my.ini. Restart MySQL and you are good to go.

@jesse what do you do for a living
Eskinder Getahun I am currently a student, I teach, and I freelance.
I'm stuck here: 31:05 , i see only ProductService.vhost.exe. Can anyone help me with this ?
The ServiceContract "IS" the interface. Everything you want your service to expose should be lined up there. By adding another Interface (Your DLL i.e.) you're just introducing a dependency to a client. Why as a Service developer would you want your clients be dependent on an outside interface?
hi... is this topic still on ? I have a question, besides linq and the foreach class, what other options do I have to retrieve data from the ADO-net model ? How do I join table infirmation (foreign keys) for example ? thanks
You can use linq for anything. Linq has everything you need to handle a database. You can use join statements with linq.
I have done every step one in one like in Your Video, but I have an Exception An unhandled exception of type 'System.InvalidOperationException' occurred in System.ServiceModel.dll
Additional information: The HttpGetEnabled property of ServiceMetadataBehavior is set to true and the HttpGetUrl property is a relative address, but there is no http base address. Either supply an http base address or set HttpGetUrl to an absolute address. Can You Help me? I can not understand why I have this exception

However, now I'm understaing why you separate the instrafaces.
Thank you again!
Does any visual studio express suffice for the needs of such projects???Or must I purchase the professional version?
Visual Studio 2015 you can download it for free
All this time I was trying to build WCF services with VS 2015 express, when I should have installed VS 2015 community. I'm all set now, although I can't manage to make my services work through public network.
OMG that took forever to figure out granted I am not as advanced in visual studio as you are. You never mention placing a reference to System.Runtime.Serialization. Any way I figured it out after redoing everything.

Usually on c#do like this
Interface temp= new implementation()
but when you define the channel factory you define like
interface temp = new interface ()
how you link to the implementation?
you cant apply method on the interface, that strange
Hey what if i want to list all of the elements from ddatabase not only first it's like Employee matchingProduct = database.Employees.First(p => p.Title == imie); and i want not only first element but all of the element wchich include in this condition????
Use .Where instead. This will return an IEnumerable of all matching entities
e.g.
IEnumerable matchingEmployees = database.Employees.Where(p => p.Title == imie);
You could also return it as a list with .ToList()
e.g.
List matchingEmployees = database.Employees.Where(p => p.Title == imie).ToList();
There is not generate from database option for the model entity in visual studio 2017.Any suggestion?
Jesse at 26.11 you resolve the issue with IWCFProductService but I am not getting that option instead I get error CS0535 that says does not implement interface Member Please Help me
Jesse,
I'm using VS 2013 express and MySQL connection is not listed. I can read the adventure works database thru MySQL Workbench. I'm running Win 8.1 and I selected the "developers" option when I installed MySQL. I had tried to due a "custom" install of MySQL selection the 3 packages you told us in the first video but I keep on having a problem with it not finding the "my.ini" file. When I selected "developers' option the installation seem to go fine. Any suggestions on how to get VS 2013 to see the MySQL server?

Great tutorial. Your voice kinda sounds like Chris Griffin lol.
Why would you create a local list variable and not just return p. Products. Tolist()
