System.Data.Entity is not available

Question

I have added .Net Standard Library 2.0 and I have installed EntityFramework 6.4.0 via NuGet Package manager, But unable to inherit DbContext in my class because System.Data.Entity is not available. What should I do to use DbContext?

Answer 1

As @magicandre1981 said, you need to upgrade to .NET Standard 2.1.

I hate all these hidden version incompatibilities! We had EntityFramework 6.2 running in a .NET Standard 2.0 project. Updating EF produced no version incompatibility warnings, even though if you look closely from EF 6.3+ it requires .NET Standard 2.1.

Edit: And the calling project is Framework 4.8, which does NOT support .NET Standard 2.1. So it's back to EF 6.2 and .NET Standard 2.0 for me.
