Add a pubternal way to clear ServiceProviderCache

[AndriySvyryd]

As a workaround for issues like #27169

Is this still a priority?

[ajcvickers]

@MeWagh It was never a priority. See release planning for information on how we decide what to work on.

Understood, thanks.

Hello can I take this issue?

This impacts us as well. We rotate our NpgsqlDataSource every 12 hours. Even though we properly Dispose the old data sources and DbContext's, we eventually get:

'Microsoft.EntityFrameworkCore.Infrastructure.ManyServiceProvidersCreatedWarning':
More than twenty 'IServiceProvider' instances have been created for internal use by Entity Framework. This is commonly caused by injection of a new singleton service instance into every DbContext instance.

Is there any way at all to get EF core to remove the old service providers?

@gbd3-en the plan on the EFCore.PG side is to stop creating new EF service providers for different NpgsqlDataSources - that should take care of your usecase (see npgsql/efcore.pg#3086).
