Microsoft Store package does not contain addins

[christophwille]

r2r and baml decompiler are missing. (vs addin project copies everything, wapproj only has ilspy.csproj reference)

A solution to this problem also ties in with #2324 (comment)

Consideration should be that the Store changes soon https://developer.microsoft.com/en-us/microsoft-store/desktop-apps/ and maybe going with a plain msi would be best (eg using https://github.com/wixtoolset/ - quick overview here https://www.ryadel.com/en/asp-net-create-msi-setup-exe-installer-project-wix-core-winforms-wpf-xaml/)

Alternatives

https://marketplace.visualstudio.com/items?itemName=VisualStudioClient.MicrosoftVisualStudio2017InstallerProjects (useable in gh actions, see actions/runner-images#1382)

https://github.com/oleg-shilo/wixsharp instead of writing XML for WiX Toolset

Some advantages:

• Getting rid of the separate solution with UWP dependencies
• Multi-TFM would be possible out of the gate

The plan after merging #2558 - keep the wapproj around for 7.2 release cycle, then remove the sln/wapproj/action and only use the MSI installer going forward for Store.
