We may want to validate that Parent, Interfaces and Attributes columns haven't changed, but it's tricky and might be overly restrictive

Customer Impact
Customers using Hot Reload with WebAssembly or mobile platforms should be able to delete custom attributes from classes in a hot reload session without the runtime crashing. Additionally customers using Blazor WebAssembly should be able to delete a
@layoutdirective without the runtime crashing.Testing
CI testing
Risk
Low. The PR removes an overeager validation check that assumed there hot reload deltas will not contain rows that modify existing types. However Roslyn does send such changes (although the modified row is logically equivalent to its previous value) when delete a custom attribute attached to a class. Note that custom attribute deletion was already working for fields and methods.
