Dependencies are not automatically loaded into the reflection-only context.

You cannot execute code from an assembly loaded into the reflection-only context. To execute code, the assembly must be loaded into the execution context as well, using the Load method.

Whether certain permissions are granted or not granted to an assembly is based on evidence. The rules for assembly and security evidence merging are as follows:


Reflecting on executable files compiled in C++ might throw a FileLoadException. This is most likely caused by the C++ compiler stripping the relocation addresses or the .reloc section from your executable file. To preserve the .reloc address, specify /fixed:no when you are linking.

The reflection-only context is no different from other contexts. Assemblies that are loaded into the context can be unloaded only by unloading the application domain.
