ASP.NET Core missing line numbers in exception

Question

I created new project: ASP.NET Core Web Application (.NET Core) and test throw new exception in controller and catch the exception. In exception is no line numbers (exception.ToString()). I added System.Diagnostics.StackTrace to project.json, but line numbers are still missing, even with debugger.

When I change Core framework project to full .NET framework, line numbers are OK. Can I get line numbers of exception in Core framework?

Answer 1

For me, enabling Portable PDB or setting Optimize didn't fix the problem.

But I tried changing the Debugging information to "Full" in Advanced Build Settings and it worked.

Follow the below procedure:

1. Open the "Properties" of your startup project.
2. Goto "Build".
3. Click on "Advanced" under Output section.
4. Change the Debugging information to "Full".

Answer 2

When I enable portable PDBs in Core framework -> line numbers are back :-)

Enable portable PDBs in project.json:

"buildOptions": {
"debugType": "portable",
...
},
