Can you get the DbContext from a DbSet?

You can get the DbContext from a DbSet instance by using the GetService method provided by the DbContext class.

Here's an example of how to get the DbContext from a DbSet:

using Microsoft.EntityFrameworkCore; // Define your DbContext and DbSet classes public class MyDbContext : DbContext { public DbSet<MyEntity> MyEntities { get; set; } } public class MyEntity { public int Id { get; set; } public string Name { get; set; } } // Get the DbContext from a DbSet instance var dbContext = myDbSet.GetService<DbContext>();

In this example, we define a MyDbContext class that contains a DbSet property for MyEntity. We can get the DbContext instance associated with this DbSet by calling the GetService method on the DbSet instance.

Note that the GetService method returns an object, so you'll need to cast the result to the appropriate type (in this case, DbContext) before using it.
