I have a WPF 4 application running on Windows XP. When I run Snoop, it picks up the application, however when I click on "Snoop this application" nothing happens. Also when I click on the magnifying glass nothing happens.
Any ideas?
If you are running your application in administrator mode then Snoop will not work unless you don't run your Snoop in administrator mode , so better check what privilege you have given to Snoop.
The new version of Snoop supports WPF 4 (http://www.cplotts.com/2010/02/14/snoop-now-supports-wpf-4-0/).
Which version are you using?
The latest and greatest version of Snoop is always available at http://snoopwpf.codeplex.com.
One thing to note is that the source code (available for download) is usually somewhat out of date ... as compared to the released bits which you can download an installer for. That is, I don't release Snoop for every fix/change I make.
For example, the currently released version is v2.6.0 ... but I have 9 work items marked for v2.6.1. Check out the Issue Tracker for more info on what is in each version.
