static member ReflectionOnlyLoadFrom : string -> System.Reflection.Assembly
Public Shared Function ReflectionOnlyLoadFrom (assemblyFile As String) As Assembly



The path of the file that contains the manifest of the assembly.



The loaded assembly.


assemblyFile is null.

assemblyFile is not found, or the module you are trying to load does not specify a file name extension.

assemblyFile is found, but could not be loaded.

assemblyFile is not a valid assembly.


Version 2.0 or later of the common language runtime is currently loaded and assemblyFile was compiled with a later version.

Dependencies are not automatically loaded into the reflection-only context. To automatically load dependencies, handle the ReflectionOnlyAssemblyResolve event and load the dependency in the event handler.

You cannot execute code from an assembly that has been loaded into the reflection-only context. To execute the code, load the assembly with the LoadFile method.

The assemblyFile parameter must refer to a URI without escape characters. This method supplies escape characters for all invalid characters in the URI.

The path specified for assemblyFile is relative to the current directory. The assembly is loaded into the domain of the caller.

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.
