Sometimes when i build my Android project i get this exception, if i build a second time it goes away. 


Error	3718	Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. Perhaps it doesn't exist in the Mono for Android profile?

> Perhaps it doesn't exist in the Mono for Android profile?

The error message is correct, in that System.Data.Linq.dll is not part of the Xamarin.Android profile, and thus it won't compile (unless you're providing your own System.Data.Linq.dll).

That said, you say it builds if you build a second time, which suggests that something else is going on. Could you please provide Diagnostic MSBuild Output for the initial (failing) build?

Another info this happens in Xamarin.Forms projects.

Thanks for the feedback, i will provide the msbuild diagnostic when i get home.
