When opening a .NET Core project in Visual Studio 2019, then all hidden folders (folders whose name start with a dot) are ignored by default.
SlickEdit should mirror this behavior when opening .NET Core projects. Otherwise potentially a lot of unwanted files become part of the workspace, which is very annoying when e.g. doing a workspace search.
For details about .NET Core project support in SlickEdit, please see
