C＃-对父程序集引用的动态加载的程序集访问

Question

I am trying to implement a plug-in style architecture. There are core, external libraries used by both the plug-ins, and in the main application. A good example of such library is JSON.NET.

As I develop plug-ins, I make reference to the same JSON.NET version referenced in the main application. When the plug-in is compiled, I have not been merging the external libraries with the plug-in, as I expected the references to resolve to the same assemblies loaded by the main application.

However, this isn't working. When I try to invoke methods of the plug-in in the main application, I am getting "could not load assembly..." error.

How to go about making the dynamically loaded plugins resolve references the main application's references?

A few considerations:

• Design your architecture in a way that you don't need the internal references from the core system. At Example you could create wrapper for the needed functions in the core which can be used in the plugins.
• in case of .NET 4.0+: unsing the dynamic keyword
• using Reflection
• Runtimecompiling
