When we change code in an existing .cs file, many CS0246, CS0103 and CS1674 error messages pop up. When the file is closed, the errors disappear. There are no compiler errors. The errors related to NLog (4.7.11) and DbContext in EntityFramework 6.4.4. It works fine in VS 17.2.6.

Welcome to Microsoft Q&A forum.
Glad to hear that this issue has been solved. Would you mind sharing your solution here, so that other forum members who get the same or similar error will be benefit :D
I doubted if this issue was caused by cache, did cleaning cache files, rebuilding project make it work?
Regards,
Tianyu
