Visual Studio 2019 16.8.4, Elements 10.0.0.2607. A solution with one Mercury project and one VB.NET project.
If I right click on a file in the VB.NET project within the Solution Explorer and choose Copy, and then select the Mercury Project, right click and choose Paste, nothing happens.
If I do the reverse (copy a file from the Mercury project and paste it into the VB.NET project, this works fine.
Obviously plenty of work-arounds, just a little annoying.
