How can I create an edmx using Visual Studio 2022 so I can get rid of Visual Studio Express 2010?

Question

I use VS 2020, but I have kept Visual Studio 2010 for 10 years because the edmx (Entity Framework) for a very old app was built using that old VS. I would really like very precise instructions explaining how I can get rid of VS 2010 but still build the edmx the way it has always been built since so much code uses that old edmx. Whenever the database needs a change, I use VS 2010 to rebuild the edmx. Perhaps this image will give more details. This is captured using Visual Studio C#2010 Express.

I am getting another computer and I don't know if I can still find Visual Studio 2010 to be installed.
