EF Core 5.0 UseSqlServer Not Found - SQL

If you are encountering the error message "EF Core 5.0 UseSqlServer Not Found," it means that you are missing the necessary NuGet package or assembly for connecting to a SQL Server database using Entity Framework Core.

To resolve this issue, you need to add the Microsoft.EntityFrameworkCore.SqlServer NuGet package to your project. You can do this easily using the NuGet Package Manager in Visual Studio or by running the following command in the Package Manager Console:

Install-Package Microsoft.EntityFrameworkCore.SqlServer

Once you have added the package, you can use the UseSqlServer method to configure your DbContext to connect to a SQL Server database:

protected override void OnConfiguring(DbContextOptionsBuilder options)
    => options.UseSqlServer("Data Source=(localdb)\\MSSQLLocalDB;Initial Catalog=myDb;");

Make sure to replace "Data Source" and "Initial Catalog" with the appropriate values for your SQL Server instance and database.

In addition, you may need to include the following using statement in your code:

using Microsoft.EntityFrameworkCore;

This will ensure that you have access to the necessary extension methods for configuring your DbContext to use SQL Server.

Overall, adding the Microsoft.EntityFrameworkCore.SqlServer NuGet package and using the UseSqlServer method to configure your DbContext should resolve the "EF Core 5.0 UseSqlServer Not Found" error and allow you to connect to your SQL Server database using Entity Framework Core.
