Loads the assembly from a common object file format (COFF)-based image containing an emitted assembly. The assembly is loaded into the reflection-only context of the caller's application domain.
The loaded assembly.
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 erload:System.Reflection.Assembly.Load method.
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.
