Steps to reproduce

This is a net48 project with mostly unit tests. The templates folder is just data for the unit tests, so we have:

  <ItemGroup>
    <Compile Remove="Features\Templates\**" />
  </ItemGroup>

However, even with this, it gives errors.

Expected behavior

No errors

Actual behavior
