.NET 7 console application using EF Core 7 why no OnConfiguring?

Question

I built a database first .NET 7 and EF Core 7 application and used the EF Power Tools to create the context and model classes. I keep reading about OnConfiguring() being in the context class. I only have OnModelCreating()? What did I do wrong?

Answer 1

Nothing. You can still override DbContext.OnConfiguring in your context if you want to but with modern patterns using DI it is rarely needed (unless you are using something like interceptors).

See also:

• If you want connection string added via OnConfiguring enable Include connection string in generated code option (note that this should not be used in production level apps)
• DbContext Lifetime, Configuration, and Initialization

Answer 2

As @Guru Stron said above, you haven't done anything wrong!

if you do need to provide additional configuration options for your context, you can override the DbContextOptionsBuilder in the OnConfiguring() method.

For example:

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) {
if (!optionsBuilder.IsConfigured) {
    optionsBuilder.UseSqlServer("connection-string-placeholder");
  }
}
