Build Failed. See the build log for detail

Question

I create a new project, click compile, and get this error:

Build Failed. See the build log for details.

In the build log there is only this:

Building: FirstProgram (Debug|x86)

---------------------- Done ----------------------

Build failed.
Build: 1 error, 0 warnings

Here is what I see:

What causes this error and how do I fix it?

Answer 1

Lots of times dealing with this error. I just closed and reopened. It happens every time I add a solution and then delete it. I think Xamarin Ide is not a really good Ide, not in Mac at least.
