I've been attempting to use the WSDL that came with SRM4 to create some powershell scripts to automate recovery plan testing. When I use the standard MS tools to compile the .NET class, everything appears to work as expected. When I attempt to create an instance of the SrmBinding, however, it hangs forever. I've also attempted to import the wsdl file into a workflow app that I have with no success (it throws an invalid index error).
I created a .Net class with the old SRM WSDL file, and it works great, so far.
