We didn’t fix the issue but you can use next workaround:
Open the .csproj file in any text editor and add next block to it:
Change the path into proper path for your oxygene project, and the guid is a ProjectGuid property from the Oxygene project. Than reload the solution in VS2017. It gives you working CC and the project will compile too.
We will let you know when we have proper fix for your issue.
