I have this weird problem that I cannot handle myself. A class in the model of my mvp-project designed as singleton causes an InvalidCastException
.
The source of error is found in this code line where the deserialised object is assigned to the instance variable of the class: engineObject = (ENGINE)xSerializer.Deserialize(str);
. It occurs whenever I try to add one of my UserControls to a Form or to a different UC. All of my UCs have a special presenter that accesses the above mentioned instance variable of the singleton class.
This is what I get when trying to add a UC somewhere:
'System.TypeInitializationException: The type initializer for 'MVP.Model.EngineData' threw an exception. ---->
System.InvalidCastException: [A]Engine cannot be cast to [B]Engine. Type A originates from 'MVP.Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'LoadNeither'
at location '[...]AppDataRoamingMicrosoftVisualStudio9.0ProjectAssembliesuankw1hh01MVP.Model.dll'.
Type B originates from 'MVP.Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'LoadNeither'
at location '[...]AppDataRoamingMicrosoftVisualStudio9.0ProjectAssembliesu_hge2de01MVP.Model.dll'
...
So I somehow have two assemblies and they are not accessed from my project folder, but from a VS temp folder? I googled a lot and only found this: IronPython Exception: [A]Person cannot be cast to [B]Person. There is a solution offered, but it concerns IronPhyton and I don't know where to use it within my project.
