Description:
My company is very concerned about the removal of NET Standard 2.0 from MySql.Data.EntityFramework. This eliminates the possibility of using EF6 in legacy systems from NET 9. We made a huge effort to have EF in NET Core. This change isn't documented and appears to have been due to the NUnit update.

You for example can add NET8 or NET9 targets but not eliminate this support. Microsoft support this.

How to repeat:
Update NET9 with EF6 project to any 9.x MySql Connector .NET. and use the lastest MySql.Data.EntityFramework with Net Standard 2.0 depreacted-

Suggested fix:
You for example can add NET8 or NET9 targets if Standard 2.0 is a problem, but not eliminate this support. Microsoft support this.
