Describe the bug When I try to "Manage Solution Extensions..." in Visual Studio Enterprise 2022 (64-bit) - Preview, Version 17.6.0 Preview 2.0 , Extension Manager 2022 Version: 1.1.82, I get this error message:

To Reproduce Steps to reproduce the behavior:

1. Open a solution
2. Right click on the solution

Isn't this a duplicate of #70 ?

I have described a fix for the problem here: https://github.com/madskristensen/ExtensionPackTools/issues/70#issuecomment-1546908590

@loop8ack Microsoft.VisualStudio.ExtensionEngineContract.dll is missing in my VS 17.5.5

@zackmuc Did the extension work for you before my update? If yes, then the broken update came afterwards and has not been released yet. However, I will need some time to look into it, so you should continue using the previous version until I have a fix.

@zackmuc I found a solution to the problem that the two versions (Normal and Preview) differ too much. I took the repository from @madskristensen, I couldn't set up AppVeyor yet, so I attached a build for you. Please test if it solves your problem, then I'll put an update online.

AppVeyor is live: https://ci.appveyor.com/project/loop8ack/extensionpacktools An update for the Visual Studio Marketplace is also coming.
