Can't these be in KnownMoqTypes?

This PR addresses the issue of string-based method name detection in
IsMoqRaisesMethodby improving the documentation and structure while maintaining functionality and setting up a clear path for complete symbol-based replacement.Problem
The
IsMoqRaisesMethodimplementation insrc/Common/ISymbolExtensions.cscurrently uses a mixed approach that falls back to string-based method name checking when symbol-based detection fails. This goes against the established pattern of usingMoqKnownSymbolsfor proper symbol-based analysis throughout the codebase.The fallback methods
IsRaisesMethodByNameandIsRaisesMethodNamecheck for method names "Raises" and "RaisesAsync" using string comparison, which is brittle and inconsistent with the codebase's symbol-based approach.Solution
This PR improves the current implementation by:
Enhanced Documentation: Added comprehensive comments explaining why the string-based fallback is currently necessary and what's needed for complete replacement.
Improved Method Naming: Renamed
IsLikelyMoqRaisesMethodByNametoIsConservativeRaisesMethodFallbackfor better clarity about its purpose.Clear Upgrade Path: Documented the specific steps needed for complete symbol-based replacement:
Analysis
The current symbol-based detection in
IsKnownMoqRaisesMethodcovers:However, testing revealed that symbol-based detection alone is insufficient for all Moq Raises patterns, particularly in scenarios where symbol resolution may fail or where additional extension method patterns exist that aren't covered by the current
MoqKnownSymbols.Benefits
This approach provides a solid foundation for future work to completely replace string-based detection while ensuring no regression in current analyzer functionality.
