WPF Inspector

WPF Inspector is a utility that attaches to a running WPF application to troubleshoot common problems with layouting, databinding or styling. WPF Inspector allows you to explore a live view of the logical- and visual tree, read and edit property values of elements, watch the data context, debug triggers, trace styles and much more. Since March 2011, WPF Inspector is open source and available on CodePlex.

I can't get it to work.. Version 0.9.5 gives me error "Object Reference Not Set" when I click Inspect after selecting my wpf application.
Any clue?

Very usefull tool I used under Windows 7 x64 and Visual Studio 2008
since I work with Visual Studio 2010, it's no longer working
if you release the source code, we could help you improve this great tool
(note : Snoop is also a good tool but it doesn't work too)

Agree with the above. We could really help you improve this great tool (and probably make it work for a wider audience).

I've been trying to use it in my win7 VS2010 box to no avail. it works on my winxp VS2008 though.

Snoop does work for WPF 3.5/4.0 and x86/x64 ... just make sure that you have the latest version at

If you have grabbed the version from Pete Blois' site ... that one ONLY works for WPF 3.5 and x86.

@Cory Plotts
The latest version works... sometimes... (many times I can't snoop into the application, the "Snoop this application" button doesn't do anything, the "Magnify" button is working)
and when I successfully Snoop the application, Snoop is stuck at the ContentPresenter of the main window, I can't "snoop" into my injected view (my project use CAB/SCSF)

Great work with this new release!
I hit a small problem:
I have two running 2 WPF applicaions and choose to attach to one of them, but WPF Inspector attaches to the other one:
- .NET 4.0 64-bit (this is Metro Twit)
- .NET 3.0 32-bit (this is my app, that I cannot attach to)

If I stop the Metro Twit, I can succesfully attach to my app.

I just realized that if I put a disabled button to register the application unless you enter a valid serial, you can enable that button easy. 0_o
Great application!

Mole is another great way to visualize WPF apps, they just put out Mole 2010 and it's really awesome for what I'm doing with WPF at work.

Very handy tool ,,, more features than snoop....

One Suggestion : The Main Inspector should not exit when we close the application we are inspecting. We have to rerun inspector every time we want to inspect.
Hope to see this in future release.

Hello Christian.
your Tool is very nice.
But, it is not possible to read complete Text of Errors, if they are very long. It is not possible to scroll, or rightclick to copy text to clipboard.
It would be very nice and good to have this feature.

WPF Inspector is an awesome stuff for a wpf developer. But i'm facing an issue with it.

can you provide any work around for this -

Commented on 3.May 2011
Sir please give demo video how to work on this? i am not able to know this one.Its showing empty.
Commented on 17.June 2011
Very promissins concept, I've been looking for something like this for some time.
But I'm having trouble attaching it to my application. Seems like no matter which application I select in the Attach box WPF inspector always attaches to itself.
