So, I MUST use C# for a uni course, just like I MUST use MSSQL Server, the big problem is that I'm running Ubuntu. I followed this guide, I mean it's from microsoft right? Can't get any of System.Windows.Form working, neither SqlDataAdapter and many more(like 99.65% of the libraries).
Anyone encountered this issue before? Or you just created a VM and waited a week for Visual to install?
This is what I get when I run dotnet run
Program.cs(4,22): error CS0234: The type or namespace name 'Forms' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?) [/home/potra/Desktop/School/School/DBMS/Test/Test.csproj]

The build failed. Please fix the build errors and run again.
The latest .NET Core, 2.1 Preview 2, does not include System.Windows.Forms.
If you'd like to use a native Ubuntu runtime, Mono supports WinForms and SqlClient.
For more information, the .NET documentation explains how .NET is implemented.

I had even changed the host now to Azure DevOps but it still show me the same thing. This has pushed me to rewrite the application from start. It runs locally okay but when i publish it, it fails.
I too faced the same issue. While publishing VS build was failing with - Unable to find dependent project references, but with release version I was able to build the solution.
The fix which worked for me was -
Update VS version to Version 16.7.3.
With this version project build passed successfully and I was able to deploy the packages...in earlier version I think there was a problem with dependency resolver.

Had similar build error when following the https://developers.google.com/drive/quickstart-cs
example in a MVC project. This example builds and executes fine in a Console application.
Found a different code example for OAuth 2.0 in a MVC application (section: Web applications (ASP.NET MVC))
https://developers.google.com/api-client-library/dotnet/guide/aaa_oauth
or also

DotNetOpenAuth.OAuth2 I find by nuget

any idea? needs to install another library package? we don't plan to have visual studio 2008 installed on that build machine.
thanks,
The Unit testing assemblies are not included in the Windows SDK. They are specific to Visual Studio. In order to run your tests you should setup a Controller with a Test Agent on the machine.
The Microsoft.VisualStudio namespace is part of the Visual Studio SDK, not the Windows SDK.
