How to handle EF DbContexts with non standard constructor?

[Kralizek]

I am instrumenting an application based on EF with Aspire. The DbContexts of the application have constructors with non standard signature (either parameterless or with parameters that are not DbContextOptions and Aspire doesn't seem to like it very much.

Unhandled exception. System.InvalidOperationException: The DbContext of type 'IdentityServerOperationalContext' cannot be pooled because it does not have a public constructor accepting a single parameter of type DbContextOptions or has more than one constructor.
   at Microsoft.EntityFrameworkCore.Internal.DbContextPool`1.CreateActivator(DbContextOptions`1 options, IServiceProvider serviceProvider)

As you can imagine from the log entry above, the application is using Duende's Identity Server to handle users.

Can you show the API you are using? Are you using the Enrich methods https://learn.microsoft.com/en-us/dotnet/aspire/whats-new/preview-4#new-enrich-methods?

I was using the classic AddSqlServerDbContext<TContext>.

builder.AddSqlServerDbContext<IdentityServerConfigurationContext>("Database", ConfigureSqlServerSettings, ConfigureDbContextOptions);

static void ConfigureDbContextOptions(DbContextOptionsBuilder builder)
{
    builder.UseSqlServer(sql => sql.MigrationsAssembly(MigrationAssemblyName).EnableRetryOnFailure());
}

static void ConfigureSqlServerSettings(MicrosoftEntityFrameworkCoreSqlServerSettings settings)
{
}

I knew about the new Enrich APIs but I failed to connect them to the issue I am having. I will give it a try as soon I can spend more on the Aspire spike I'm running.

Thanks a lot!
