Version Information: 4.2.1 (Stable 4.2.1.102/6dd2d0d Thu Nov 12 09:52:44 UTC 2015); ASP.NET Version: 4.0.30319.17020 Powered by Mono

MonoDevelop I have in 6.0 version

And file: Views/Home/Index.cshtml exists

Do you know anybody what can be wrong?? Thanks

回答1:

The described exception happens in mono when your code tries to produce really async execution.

Mono does not support the async pipeline.

I make pull request for mono like described in this GitHUB post. It makes synchronous execution of asynchronous web API stack.

It is derived from these SO questions:

Mono .Net support for async await?
Mono with Owin Authentication
404 response appended to webapi response
Mono: The view 'Index' or its master was not found

Now you may use async pipeline with this fix for Mono.

I received the same error. I was compiling on my windows machine but running on Mono in Raspbian. So when I typed it in I should have been paying attention to case.

I typed "index" instead of "Index" once and chrome would not simply let me retype it to include the capital "I".

I then change the file name to match just to get passed the error and my page loaded.
