I am getting a 'System.Reflection.ReflectionTypeLoadException' when trying to access entities defined in an encrypted executable.

Are the types that are being loaded by reflection defined in your main executable assembly or in sub-assemblies. Whether you can load types defined in encrypted assemblies via reflection will depend on how the loading code is implemented. If it first searches loaded assemblies for the type then you could ensure that the assembly is loaded by create a type or accessing a method defined in the assembly from your main assembly. This will force loading of the encrypted assembly.

If the reflection based loading code does its own probing and uses Assembly.LoadFrom to load the assembly then this may not work.

Thank you for the quick reply.

Everything is loaded from the main assembly so the types should be already available. I will investigate further to confirm.

You are right. It is trying to load an external assembly which is also encrypted.

I am going to try to merge the assemblies so they are contained in the main executable.
