I'm referencing MSBuildStructuredLogger 2.1.820 in an assembly which is multi-targeted to net6.0 and net7.0. Unit tests on net.7.0 work fine, but tests on net6.0 fail with the following error:

System.IO.FileNotFoundException : Could not load file or assembly 'Microsoft.Build.Framework, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

Can be reproduced on the release/3.0 branch of https://github.com/cake-contrib/Cake.Issues.MsBuild/tree/3.0.0

Is there anything I can do to get the tests running under net6.0?
