So yesterday everything was working just fine. But today when I was to open my project it no longer is working. When I try to clean/build I just get the same error Error: Unknown MSBuild failure. Please try building the project again.
I tried to open Xamarin Studio and there the project builds/cleans just fine but in Visual Studio it's not working at all.
I tried googling it and it seems this is a problem, but I found no solutions to it.
Any help is appreciated!
