I need to debug a full-trust application either by specifying a URL or, ideally, from within the web app I am intending to deploy it to. I've tried the following:
-
Running "PresentationHost.exe -embedding" from the command-line, attaching through Visual Studio. The IDE shows that my breakpoints are valid until I actually attempt to load the .xbap file, at which point it shows that there are no symbols loaded. None of my breakpoints are hit. I've tried "mage -cc" before doing this per several recommendations elsewhere
Found it. The "PresentationHost.exe -embedding" will work, provided that you select the .pdb file to be published, which it is not by default. This follows from what I saw before, where the debugger appeared to have symbols then not, once the app actually loaded. To clarify:
-
- Go into the Publish tab on the project properties
- Click "Application Files..."
- Check "Show all files"
- Select the .pdb file for the executable to be included.
- Republish
- PresentationHost.exe -embedding
- Attach to process or set the project to run this out of the debug tab
- Launch the web page in a browser and navigate to the xbap file, breakpoints should be hit now.
If you have access to source code and you deploy on localhost you can simply add System.Diagnostics.Debugger.Launch(); in your code. This will allow You to attach with VS to any process your XBAP is using.
