I recently updated OC 1.0,0-beta to 1.7.0 and it works, but it depends on what the modules you have. I advice you to do an increamental update instead

This sounds like a compile time error. Isn't it? The errors are saying your missing using statement.

Make sure your project is using .net 8, since we dropped support to other frameworks in OC 1.8-previews. Then make sure you are able to build the project locally and fix any compile time errors.
