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

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.

Helped but still not loading everything.

Need a better demo.

VB Event syntax:

AddHandler AppDomain.CurrentDomain.ReflectionOnlyAssemblyResolve, AddressOf CurrentDomain_ReflectionOnlyAssemblyResolve

Public Function CurrentDomain_ReflectionOnlyAssemblyResolve(ByVal sender As Object, ByVal args As ResolveEventArgs) As Assembly
Try
Dim *** As Assembly = System.Reflection.Assembly.ReflectionOnlyLoad(args.Name)
If Not *** Is Nothing Then
Return ***
End If
Catch
End Try

Dim parts As String() = args.Name.Split(",".ToCharArray()(0))
Dim File As String = Path.GetDirectoryName(m_file) + "\" + parts(0).Trim() + ".dll"

Return System.Reflection.Assembly.ReflectionOnlyLoadFrom(File)

End Function

Also requires FileIOPermission with FileIOPermissionAccess.PathDiscovery      David M. Kean - MSFT   |   Edit   |   Show History
This method also requires FileIOPermission with FileIOPermissionAccess.PathDiscovery for access to the information in the path itself.
