问题
I have this error:
Runtime error CS0234: The type or namespace name 'StiOracleSource' does not exist in the namespace 'Stimulsoft.Report.Dictionary'
I developed (VS 2012) an application that uses MEF (.NET 4.5) to interconnect several binary assemblies loaded from a database. One of its separate plug-in assemblies (implemented as an stand-alone executable) has dependency on a third party DLL (Database adapter) that cannot be included in the main application. When I run the plug-in as a stand-alone application everything goes fine but if I load that assembly as a MEF part into the main application then I got CS0234 error runtime despite I provide the third party DLL reference using AppDomain.CurrentDomain.AssemblyResolve event approach. Referencing the third party DLL in the main application doesn't help.
Can anyone explain why the plug-in assembly runs smoothly as a stand-alone application and why it is broken when it is executed as a part of the MEF?
