Customer Impact
How a COM server is activated can obscure how we determine the
IIDof a COM interface method. This matters in scenarios involvingISupportErrorInfo. A user reported this in #121252.Regression
This is a regression from .NET 9. It was introduced in #117690.
Testing
Tests were updated to validate this behavior.
Risk
Low. This only impacts COM scenarios involving
ISupportErrorInfo.
