gles2動態壁紙轉換爲C＃（xamarin）符合錯誤「... mono.android.TypeManager不能應用於

Question

我試圖用C＃編寫一個android動態壁紙使用xamarin
這樣做，我轉換在GLWallPaperService代碼在這裏發現到C＃：
http://www.learnopengles.com/how-to-use-opengl-es-2-in-an-android-live-wallpaper/

（直接跳轉到這裏Java實現：https://github.com/learnopengles/Learn-OpenGLES-Tutorials/tree/master/android/AndroidOpenGLESLessons/src/com/learnopengles/android/livewallpaper）

編譯後，我得到的錯誤：

Activate(java.lang.String,java.lang.String,java.lang.Object,java.lang.Object[]) in mono.android.TypeManager cannot be applied to (java.lang.String,java.lang.String,com.[redacted].OpenGLES2WallpaperService.OpenGLES2WallpaperService_OpenGLES2Engine,java.lang.Object[]) mono.android.TypeManager.Activate ("com.[redacted].OpenGLES2WallpaperService/OpenGLES2Engine, GameUtilClassLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "com.[redacted].WallpaperServiceUtil.OpenGLES2WallpaperService, GameUtilClassLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", this, new java.lang.Object[] { OpenGLES2WallpaperService.this }); D:\[redacted]\obj\Debug\android\src\com\[redacted] \wallpaperserviceutil\OpenGLES2WallpaperService.java

這是我的C＃實現......遺憾的長度：

我指定版本的SDK版本8，並使用Visual Studio 2012
任何幫助表示讚賞。

這是我們的Android Callable Wrapper生成器代碼中的一個錯誤：我們不能正確支持C＃中的「中間」非靜態內部類。具體而言，GLWallpaperService.Engine正確生成，但OpenGLES2WallpaperService.OpenGLES2Engine不正確。請致電bugzilla.xamarin.com。
