An unhandled exception of type 'System.TypeLoadException' occurred in PresentationCore.dll
Additional information: Method 'DeleteConfigPanel' in type 'GEMMF.ServiceProvider.GEMMFServiceProvider'
from assembly 'GEMMF.ServiceProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.
