Visual Studio 2017 not opening .modelproj

Question

What workload/component needs to be installed in order for Visual Studio 2017 Enterprise to open existing .modelproj (UML-based design projects)?

Answer 1

I also get this error. I explain how I fix;

1. Open Visual Studio Installer
2. Click Modify
3. Go individual components tab
4. Then check all checkboxes inside Code Tools

This @Ben solution from the comment:

1. Open Visual Studio 2017
2. Tools menu
3. Get tools and Features... selection
4. Individual Components tab
5. Code Tools group, Then check all checkboxes inside

When you restart visual studio 2017, it must be fixed. Hope it will help someone
