Hi

If I select the "designer background" (i.e. the Entity Model), the Property Grid remains blank (see screenshot). I can add an entity to it and if I select that entity, the properties are displayed properly and I can edit them.

In addition, if I try to generate the code from the designer, I get this:

Running transformation: System.FormatException: Input string was not in a correct format.
at System.Number.ParseDouble(String value, NumberStyles options, NumberFormatInfo numfmt)
at Sawczyn.EFDesigner.EFModel.ModelRoot.GetEntityFrameworkPackageVersionNum() in C:\Code\EFDesigner\src\Dsl\CustomCode\Partials\ModelRoot.cs:line 335

I've tried this on two different machines, in two different domains, with two different users and two different VS2019 setups (pro vs. enterprise & different extension collection) and it makes no difference.

What am I missing? My VS2019 is up to date and I have tried the project in question in both .netCore3.1 and .net5.0 configurations - no difference.
