I try to use facebooksdk.net in my WP8 Unity3D Plugin. Facebook.dll and Facebook.Client.dll and their fakes in correct folders, but error occure. Is there any way to fix it?

Error building Player: Exception: Failed to run assembly preprocessor with command line “Temp/StagingArea/Data/Managed\Facebook.Client.dll” -injectCtor -assemblyPath “Temp/StagingArea” -pdb.[Temp/StagingArea/Data/Managed\Facebook.Client.dll]

It’s a bug. It will be fixed in 4.3.

It is caused by classes inheriting from classes in Windows Phone SDK, such as XAML Page. The only way to avoid it is move those classes outside of plugin and add them to the exported visual studio solution.
