public static TService GetRequiredServiceWithAssertion<TService>(this IServiceProvider? serviceProvider) where TService : notnull

Parameters

serviceProvider IServiceProvider

Remarks

This member is convenient for returning global-state (non-scoped) services like those registered with AddSingleton(IServiceCollection, Type, Type) (e.g. Microsoft’s IConfiguration contract).

This member also saves one line of code for the following scoped ServiceProvider pattern:

using IServiceScope scope = _factory.Services.CreateScope();

IMyRepo myRepo = scope.ServiceProvider.GetRequiredService{IMyRepo}();
Assert.NotNull(myRepo);

where _factory is an instance of an xUnit fixture like IClassFixture{WebApplicationFactory{Program}}.
