Do you think these lines are necessary(The question is not related to this PR)? https://github.com/MudBlazor/Templates/blob/c5294d177ab4a90a8e5fc34e8a777c061f75958e/src/MudBlazor.Templates.csproj#L50-L56

Or did they get added to the csproj by accident? I removed them locally and built using nuke pack, and the NuGet package was the same as it was with these lines.

I think you're right, that they got added by mistake and can be removed.
