Hi, I've migrated an existing noncritical xaf app to net5 (the rest of assemblies were left as there are) It works very well!

found an exception while using right-click for adding a summary to a group

The error occurred:

Type:       NullReferenceException
Message:    Object reference not set to an instance of an object.
Data:       0 entries
Stack trace:

i do not see how it relates to .net5, probably your system changed a bit. Anyway I can attempt a fix in the next minor

eXpand.lab release 21.1.501.2 includes commit that relate to this task:

• Null Reference exception #883

Please test if it addresses the problem. If you use nuget add our LAB NugetServer as a nuget package source in VS.

To minimize version conflicts we recommend that you switch to PackageReference format and use only the eXpandAgnostic, eXpandWin, eXpandWeb packages. Doing so, all packages will be at your disposal and .NET will add a dependecy only to those packages that you actually use and not to all (see the Modules installation-registrations youtube video).

Thanks a lot for your contribution.
