is this linked to the #844 ?

[apobekiaris]

not really however in the next minor tests/easytests are now on .net5.0 so I consider the packages fully compatible to anything >=net461

eXpand.lab release 20.2.601.1 includes commit that relate to this task:

• port all eXpand agnostic packages to netstandard2.0 #867

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.
