Microsoft.EntityFrameworkCore.InMemory 9.0.5

Microsoft.EntityFrameworkCore.InMemory is the EF Core database provider package for the built-in in-memory database.

This database provider allows Entity Framework Core to be used with an in-memory database. While it has become common to use the in-memory database for testing, this is discouraged. For more information on how to test EF Core applications, see Testing EF Core Applications.

Usage

Call the UseInMemoryDatabase method to choose the SQL Server/Azure SQL database provider for your DbContext. For example:

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    optionsBuilder.UseInMemoryDatabase("MyDatabase");
}
