Description

Adds the ability for the metadata refresh to be done as a blocking call, as per 8.0.1 behavior.

This is done through the 'Switch.Microsoft.IdentityModel.UpdateConfigAsBlocking'.

If set, configuration calls will be blocking on update, and exceptions when requesting new metadata will be returned to the caller

Fixes #3192

• A corresponding boolean property 'UpdateConfigAsBlocking' (similar to 'UseRfcDefinitionOfEpkAndKid') should be implemented to allow proper evaluation of the blocking switch.

AppContext.SetSwitch(UpdateConfigAsBlockingSwitch, false);

src/Microsoft.IdentityModel.Protocols/Configuration/ConfigurationManager_Blocking.cs:71

• [nitpick] Consider reusing a static Random instance or using a thread-safe alternative for jitter calculation to avoid potential issues with seed duplication during rapid successive calls.

TimeSpan _bootstrapRefreshIntervalWithJitter = TimeSpan.FromSeconds(new Random().Next((int)_bootstrapRefreshInterval.TotalSeconds));
