Always tell what actually happens rather than just that "it doesn't work". Error messages are intended to tell you (and us) what goes wrong rather than having to guess.
I'm not even sure if you mean this is a runtime error rather than a compile time error. It could be anything that causes this line to fail including this WebApiConfig class to be not declared at all or not properly ???)
Severity Code Description Project File Line Suppression State
Error CS0103 The name 'WebApiConfig' does not exist in the current context WebAPI-DI V:\ETC Projects\Dependency Injection for Web API Controllers\C#\WebAPI-DI\Global.asax.cs 14 Active
The compiler error is telling you the compiler cannot find WebApiConfig.Register. Usually this is due to a missing "using" statement at the top of the file (Global.asax.cs).
Place your cursor over the error, Visual Studio should pop up a help window that displays a list of possible fixes including adding the "using" line.
There can be other issue with your code.
Unfortunately, you did not share the WebApiConfig.cs file so we cannot see if the namespaces match. The standard Visual Studio templates add this configuration automatically. Are you trying to configure Web API by hand? If
so, create a new project and review the template code. Compare the template code to your code.
gebhard, i am happy to say that i fixed the error in the Api project. It was the WebApiConfig file. I was trying to hand build it so that why it failed. But when i compared the code i could see what to do to resolve the issue thanks. Markus.

What is the error? Can you share the WebApiConfig class?

It is the https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-messages/cs0103 error I suspected.
Make sure it is declared. Or this class is declared in a namespace which is not in scope (missing a "using" ?)
