MSRDC Is Now Supported in Remote Desktop Manager - The Devolutions Blog
our first tests were successful and I'm quite positive that V7 can ship with MS RDC support. Although it will not resolve the WVD support issue. I talked to the developer of the MsRdpEx library and right now this is not supported because MS lacks a couple of APIs and hooks to make that happen. Not sure if and when MS is providing something which will enable support for this.
