Display lines number in Stack Trace for .NET assembly in Release mode

• Go into the Properties window for the project where you want to see stack trace line numbers.
• Click on the Build "vertical tab".
• Select "Release" configuration. Check the DEBUG constant parameter.
• Uncheck the "Optimize code" parameter to avoid the occasional trace issue with inlined code (this step is not essential).
• Press the Advanced... button and choose Output -> Debug Info -> pdb-only.
• Deploy the generated .pdb file with the assembly.

Implemented with the comment below:

• One other thing to check is in the "Package/Publish Web" section that the "Exclude generated debug symbols" checkbox is also unchecked

In VS2012 you need to uncheck "Exclude generated debug symbols" in the Package/Publish Web section of the properties as well.

My solution

Copy pdb file in same folder that executable file.

now i can view the line number when run the exe file.

this is reason
