Features:
View execution flow live from the Visual Studio editor:
- Attach the Visual Studio debugger to the target process.
- Navigate to the file you want to view its flow. It may take a second before the highlighted lines appear.
- If a line is not executing anymore, the line background will change its color to blue, indicating that it previously executed.
View inline variable changes from the Visual Studio editor:
- Attach the Visual Studio debugger to the target process.
- Place the cursor anywhere in the function in which you want to view the variable changes. The extension will show changes to variables that happened on each line in real time.
- If the instrumentation of the function is causing performance issues in your debugged application, you can toggle it anytime in the top VS menu: Extensions, D0, Show inline variable changes.
View execution flow before breakpoint:
- Place a breakpoint in Visual Studio.
- When a breakpoint is hit, the extension will show the execution flow in the function before the breakpoint. If a line was executed more than once, the extension will show a number alongside the line that indicates how many times that line was executed.
