SqlServerValueGenerationStrategy does not exist

When i try to run the project it gives the following error due to lack of package

The name 'SqlServerValueGenerationStrategy' does not exist in the current context

I tried installing Microsoft.EntityFrameworkCore.SqlServer but visual studio acts like it wasnt installed.

Its look like installed and defined at my .csproj file.
