Compiler crashed with code: 1

Hi,

I was developing for Android in Xamarin Studio, when suddenly my app does not compile anymore with error: Compiler crashed with code: 1

So, according to http://forums.xamarin.com/discussion/1699/microsoft-csharp-targets-build-error I enabled diagnostic build output and found the error was that the Workflow/obj/Debug/Workflow.dll does not exists.

How to solve this problem?

Thanks in regard,
