I'm having a problem on Visual Studio 2015 with BimlExpress Build 5.0.63316.0. It installs fine, but I cannot edit Biml files inside VS. I can compile fine. I can go back to an earlier version and edit files, but sometimes the errors aren't helpful which is why the newer version is preferred, but the inability to edit a file is a problem. I have the same file/app privileges when I revert so I don't think that's the issue. Is there any chance that the BimlExpress 2018 R3 Preview will fix this issue?
