Snoop: Now Supports WPF 4.0
This is just a quick post to point people to the fact that I have updated Snoop on CodePlex (http://snoopwpf.codeplex.com/) such that it now supports WPF 4.0.
If you try to Snoop a WPF 4.0 application with the WPF 3.5 version, you will get the following error message:
I speculate that this is because there is a brand new CLR with .NET 4.0 (WPF 4.0) applications. Yes, that’s right, a brand new CLR. We haven’t had one of those for a while.
If someone can confirm this or provide a better understanding of why I can’t Snoop WPF 4.0 applications without retargeting Snoop to .NET 4.0 … please shed some light for me.
So, there are now 4, count them, 4 versions of Snoop:
- Snoop 32-bit for WPF 3.5
- Snoop 64-bit for WPF 3.5
- Snoop 32-bit for WPF 4.0
- Snoop 64-bit for WPF 4.0
- You need to use the right version of Snoop in each particular situation … otherwise … thar will be problems, matey!
I have also added another label to the app chooser so that you know which version you currently have up. Take a look … this is what it looks like for the 64-bit/WPF 4.0 version:
Let me know if you have any problems by creating a discussion (or participating in a current one) on the http://snoopwpf.codeplex.com site.
Enjoy and happy Snooping! 
I think it is a great tool! One thing, though, I downloaded Snoop 2.7.0 which is marked as the latest. It doesn’t make any claims that it is snooping a 64-bit application (or a 32-bit application) as your images show. I am wondering whether this is part of the release or it is not yet released.
@Antonio, this blog post is quite out of date with what we have posted at http://snoopwpf.codeplex.com.
The version at CodePlex handles all flavors of WPF (and bit-ness) seamlessly. Check out this blog post for more info.
Hello,
I’ve tried using Snoop, but it never seems to find the window of the application i’m running. I mean … I run my WPF application and refresh Snoop, but it does not recognize my application.
Has any one else run across this problem?
@eran, the most common problem … is that the application you are running … is elevated (running under administrator privileges) … while Snoop is not. Try running Snoop as an Administrator … and see if that works.
Also, the best place to discuss issues with Snoop is at CodePlex: http://snoopwpf.codeplex.com/discussions
Hope that helps you.
