How to debug LinqPad query in Visual Studio Debugger?

I can attach the debugger and get it to break - but it has troub开发者_如何学Gole finding the .cs file, I think LinqPad deletes it as part of its build.. 8-(

If you call

Debugger.Launch();
Debugger.Break(); 

to initiate the breakpoint within your LINQPad script, LINQPad will guess that you want to use VS to debug your script and won't delete the .cs file.

• Start LINQPad
• In VS, open Debug -> Attach to Process...
• Choose LINQPad.exe
• Set breakpoint in your code called by LINQPad C# code, or write Debugger.Break() in your LINQPad script where you want the debugger to halt.
• Execute the script from LINQPad and watch the magic.

If your LINQPad code is calling a method in some referenced C# assembly and you want to debug that assembly in Visual Studio 2015, this worked for me:

1. Build your solution.
2. Optionally, run your LINQPad script, let it crash, etc. In the lower right LINQPad status bar, notice the PID in light blue coloring.
3. In VS, CTRL + ALT + P to attach to process. Attach to the LINQPad UserQuery process with the PID you saw.
4. Place a breakpoint here in VS.
5. Run the linqpad query and pop over to VS. You should hit your breakpoint!
