The analyzer runs for property assignment operations, including those in attributes. To check whether the property assignment should warn, we look for RUC on the containing symbol. However, assembly-level attributes are contained in the global namespace, which has a null containing type.

This will have to go through QB approval. Could you make the change in main first? I'm not sure it will meet the bar without a customer report. |

The analyzer runs for property assignment operations, including those in
attributes. To check whether the property assignment should warn, we
look for RUC on the containing symbol. However, assembly-level attributes
are contained in the global namespace, which has a null containing type.
Customer Impact
Assembly-level attribute with property assignment causes a crash in the RequiresAttribute analyzers. #2563 hits what is likely this issue.
Testing
Unit tests added in this change. This was originally discovered as part of running the analyzer over the existing linker tests as part of #2523.
Risk
Very low risk - the change adds an extra null check without impacting other code paths.
