How to Display Stack Trace Line Numbers in .NET Release Builds?

Debugging .NET Release Builds: Getting Stack Trace Line Numbers

Accurate stack traces are crucial for efficient debugging. However, Release builds often omit line numbers, hindering troubleshooting. This guide explains how to resolve this in .NET applications.

Step 1: Adjust Release Build Settings:

1. Open your project's Properties window.
2. Go to the "Build" tab.
3. Select "Release" from the "Configuration" dropdown.
4. Disable "Optimize code" to prevent code inlining, which can obscure line numbers in the stack trace.

Step 2: Generate PDB Files:

1. Click "Advanced..." in the Build settings.
2. Under "Output" -> "Debug Info", select "pdb-only".
3. Rebuild your project. This creates the .pdb file containing debugging symbols.

Step 3: Deploy PDB Files:

1. Deploy both the .dll and its corresponding .pdb file to your target environment (server, etc.).

Further Considerations:

• Make sure "Exclude generated debug symbols" is unchecked in your publishing settings (e.g., "Package/Publish Web").
• If line numbers remain absent, deploy .pdb files for all related projects within your solution.

Following these steps ensures that your .NET Release builds include line numbers in stack traces, significantly improving your debugging capabilities.
