It filters application methods from framework methods to focus on user code. + +## Remaining Limitations + +### 1. Dynamic/Reflection Calls +The tool cannot detect methods called through reflection or dynamic invocation, as these don't go through normal JIT compilation. + +### 2. External Triggers +Methods triggered by external events (webhooks, scheduled tasks, message handlers) may not be exercised during profiling scenarios. + +### 3. Lazy Initialization +Methods that are only called under specific conditions may be missed if those conditions aren't met during profiling. + +### 4. Interface/Abstract Methods +Abstract methods and interface definitions show as having no source location since they have no implementation body. + +## Alternative Approaches + +### 1. Code Coverage Integration +Consider using code coverage tools for comprehensive analysis: +```bash +dotnet test --collect:"XPlat Code Coverage" +``` +Code coverage data can complement JIT trace analysis for test-driven scenarios. + +### 3.
