WPFPerf Performance Profiling Tools for WPF 4 is now available!
The WPFPerf tool comprises of a suite of performance profiling tools that allow you to analyze the run-time behavior of your WPF application and point to potential performance bottlenecks.
We finally release the version that also supports .NET Framework 4 (WPF 4).
This version of the tool (WPFPerf 4) will allow you to profile both WPF 3.5 SP1 and WPF 4 based applications.
The WPFPerf 4 tool is included with the Windows SDK for Windows 7 and .NET Framework 4 (Windows SDK 7.1). So you are welcome to download and send us your feedback.
By the way, the tool itself will run on machines with only .NET 3.5 SP1 or only .NET 4, if both are present it will use .NET 3.5 SP1.
Also, I am not sure how many people had a chance to look at the documentation that is installed with the tool , but we think it is very useful so don't forget to check it out.
Update (6/14/2010):
We heard that few folks complain that the Visual Profiler cannot correctly attach to the WPF application in the new WPFPerf for WPF 4.
After some research we think this has to do with a bug in our DateTime initialization which cause anyone in a time zone > GMT to not get any data in VisualProfiler (for a few hours at least).
Until we post a fix, a temporary workaround is to set your time zone > GMT (e.g.to Eastern or Pacific Standard Time Zones) when you first attach VisualProfiler.
Please try this workaround and let us know.
Update (8/24/2010):
A patch to that fixes the bug in Visual Profiler for certain time zones is now available.
See here.

For me also says 'This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded' for a wpf 4.0 application. Also, the Visual Profiler does not do anything when I choose to profile my WPF 4.0 applicationAnonymous

the Perforator works for me, but the Visual Profiler can't collect any data while profiling, what's wrong ?Anonymous

Hi Guys
We have seen similar reports with the latest WpfPerf tool.
In some situations simply setting focus on the app or resizing it seems to address the issues w/ Visual Profiler.
If this did not help, to help us investigate, can you please provide more data. E.g.:
1.What OS / Service pack are you running ? Is it 32 or 64 bit OS?
2.Is your app 32 or 64 bit (e.g. complied for “x86”, “x64” or “AnyCPU” ?)
3.Is your app targeting NET4 or 3.5 SP1?
4.Do you have both .NET 3.5 SP1 and NET4 installed on your machine?
5.Is WpfPerf not working when you attach the app ? or launch it from WpfPerf ? (can you please try both)
6.Are you doing anything unusual in your app (e.g. Hosting 3.5 from your NET4 app, profiling XBAPs)
7.Is the issue only w/ Visual Profiler or also Perforator ? Thanks in adavnce.

I'm running version 3.1.0.0 of the PPT for WPF. It works fine for net3 apps but dose not reconize net4 apps. I click Launch Process and select my application and click Launch. The app starts but the profiler is still waiting for the app to start. I've tried to change the timezone but it dose not fix the problem.Anonymous

Forgot to mention: When the app is running and I choose to select process the aplication is shown in the list but is grayed out and its not possible to select it.Anonymous

Found the problem - the 7.1 dose not update the WPF Performance toolkit. I looked through the 7.1 installer log and found the url to the toolkit, downloaded it and installed it. Now it works fine....Anonymous

Sigurdur, could you share where you found the installer log or the link to the toolkit? I'm having the same problem and searching for the log...Anonymous

How do I get the EventTrace enabled?, I have a problem where the WPF app stops responding to the mouse and I think the WpfPerf / Event Trace might be helpful. Unfortunately I only see Perforator and Visual Profiler, and if I try to add EventTrace.dll then I get 'not tools found' ThanksAnonymous

It looks like this wonderful tool has been abandoned by MSFT :(, isn’t it? How about you, Jossef? Should we use the Visual Studio Profiler instead?
