The VSTHRD103 analyzer flags calls to synchronous methods where asynchronous equivalents exist when in an async context. However, some APIs have async versions that are significantly slower, less efficient, or simply inappropriate for certain use cases.
This PR adds the ability to exclude specific APIs from VSTHRD103 diagnostics using AdditionalFiles, following the same pattern established by the VSTHRD010 analyzer.
Changes
Core Implementation
FileNamePatternForSyncMethodsToExcludeFromVSTHRD103regex pattern for the new configuration fileMethodAnalyzerfrom static to instance-based to store excluded methodsCommonInterest.ReadMethods()andQualifiedMember.IsMatch()for consistencyConfiguration
Users can now create a file named
vs-threading.SyncMethodsToExcludeFromVSTHRD103.txtwith the following format:Documentation
configuration.mdwith details about the new configuration optionVSTHRD103.mdto reference the configuration capabilityTesting
Example Usage
Before this change, calling
SqlDataReader.Read()in an async method would always generate a VSTHRD103 warning even thoughReadAsync()might be inappropriate for the use case.With this change, teams can exclude such methods:
Success Metrics
✅ Reuses existing parser: Uses the same
CommonInterest.ReadMethods()infrastructure as VSTHRD010✅ Comprehensive testing: Added tests verifying diagnostics are suppressed for excluded APIs while preserved for others
Fixes #1464.
