I'm using MonoRemoteDebugger on a ARM machine based on a OpenEmbedded OS. I'm able to start MonoRemoteDebugger.Server and my program is well transfered from my VS to my ARM machine and then executed. But breakpoints don't work at all : "this breakpoint will not currently be hit. No symbols have been loaded for this document. Also, when my program ended, I've the following error from MonoRemoteDebugger.Server :

How can I fix ?

Thanks

Did you test on simple console application? Current version doesn't support breakpoints on Thread.

Displaying 'unexpected end of file' is normal when the program ended.

Same issue as above. Debugging on a Raspberry PI zero.

The debugger knows its attached and responds to the stop command but but no symbols are loaded. Using .NET 4.5.2 Application runs fine just can't break point.

Have the same problem on the Raspberry Pi. I like this tool because it's really easy to set up and it would be great to have support for the Raspberry and VB .NET so I can get rid of printing debug info to the console.

I'm sorry but I don't know VB.net so can't test it.

Any progress on this issue? I'm having the same problem. Trying to debug a very basic C# console application (just printing helloworld from Main) using Mono 4.0.3 on an ARM-based embedded Linux machine, and while the application starts and runs fine when I select remote debugging from the MonoRemoteDebugger menu item, breakpoints do not get hit. While the application is running breakpoints are disabled with the "Breakpoint will not be hit. No symbols have been loaded for this document" hint.

Please let me know if there's anything I can do to help you diagnose what's going on here.
