“cannot find symbol: __FastDevLauncher” blocking deployment to Android Emulator

问题

I'm porting a Windows Phone app to Android using Xamarin Studio and MonoGame.

Set up has gone very smoothly, but when I try to deploy the project to the emulator, I get the following errors:

---

C:\Users\croberts\Documents\Visual Studio 2010\Projects\Shelter_Port\Shelter_Android\Shelter_Android\obj\Debug\android\src\mono\TrialSplashScreen60e2a7ae51784c7983049dbf7b06b10c.java(101,101): Error:  cannot find symbol

symbol  : class __FastDevLauncher

location: package mono.android

Intent intent = new Intent (TrialSplashScreen60e2a7ae51784c7983049dbf7b06b10c.this, mono.android.__FastDevLauncher.class);

---

I haven't been able to find anything when google searching that mentions the __FastDevLauncher class, and the TrialSplashScreen#####.java suggests maybe it's something to do with my using the 30 day trial of Xamarin?

Regardless, I'm stumped as to where to start looking for a fix as it's not anything directly referenced in my code.

Thanks in advance for any help.

Building the MonoGame libraries from source fixes this issue. It seems there was a linking error between the Xamarin 2.0 release and the MonoGame 3.0.0.0 release. I downloaded the latest stable source for MonoGame and built the libraries alongside my own source and the build error vanished.
