      Consider the following code snippet:

      var uri = "mongodb+srv://AWS_KEY:AWS_PRIVATE_KEY@cluster441.ebdql.mongodb.net/<dbname>?authMechanism=MONGODB-AWS&authSource=%24external&retryWrites=true&w=majority";
var mongoURL = new MongoUrl(uri);
var client = new MongoClient(mongoURL);
Console.WriteLine("Finished!");

      Construction of the MongoClient instance fails with the following stack trace:

      Unhandled Exception: System.ArgumentException: A MONGODB-AWS source must be $external.
Parameter name: source
   at MongoDB.Driver.MongoCredential.EnsureNullOrExternalSource(String mechanism, String source)
   at MongoDB.Driver.MongoCredential.FromComponents(String mechanism, String source, String databaseName, String username, MongoIdentityEvidence evidence)
   at MongoDB.Driver.MongoClientSettings.FromUrl(MongoUrl url)
   at MongoDB.Driver.MongoClient..ctor(MongoUrl url)
   at tour.Program.Main(String[] args) in /shared/csharp/Program.cs:line 14

      If we change authSource=%24external to authSource=$external, the code works as expected. If we change the scheme from mongodb+srv:// to mongodb:// (and switched to the correct hostnames), it also works as expected.
