Often on twitter I see posts like “I just downloaded X, it looks awesome. Is it WPF?” One way to easily answer that question for yourself is to download snoop and run it. If you hit refresh and the application shows up, it’s a WPF app. If not, well, it’s not 
This is Windows Client Developer roundup #11. The Windows Client Developer Roundup aggregates information of interest to Windows Client Developers, including WPF , Surface, Windows 7, XNA, Windows Forms , and some Silverlight . If you have something interesting you’ve done or have run across, please send me the URL and brief description via the contact link on my blog. This week I’m on campus in Redmond, and at the MVP Global Summit. I’m looking forward to seeing lots of Silverlight and WPF goodness, as well as meeting folks in the community
Once upon a time, Pete Blois at Microsoft created the awesome WPF utility Snoop. Snoop is an indispensable utility for inspecting and debugging WPF applications. It’s also just cool to play with. Snoop is a small toolbar that sits up in the corner of Windows, waiting for WPF applications to show up. When you select one, you can then “snoop” around to see what’s in there. For example, here’s Snoop working on Seesmic. Notice the hover preview you get for items in the tree

As you’re moving all of your Silverlight solutions into Visual Studio 2010, you might encounter an error on compile like so: System.IO.FileLoadException: Could not load file or assembly ‘file:///C:devSilverlightxxxyyy.dll’ or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0×80131515) File name: ‘file:///C:devSilverlightxxxyyy.dll’ —> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information. This error is due to referencing one or more assemblies that were downloaded from the web and perhaps extracted from a ZIP file - things such as third party controls.

VS2010: The "ValidateXaml" task failed unexpectedly
One of the cool features of SharePoint 2010 (currently in beta) is that you can set it up on a Windows 7 machine. This means that as a SharePoint developer you no longer have to run a Server OS. To get started I downloaded the SharePoint 2010 Foundations beta from here . You will also need Visual Studio 2010 which you can download from here . To setup SharePoint 2010 on Windows 7 you need to follow this guide which explains how to configure the setup process to run on Windows 7 (it is only one change to an xml file). Make sure you install all the prerequisites which I won’t list here (they are listed in the guide). It will still install even if you don’t, but you will get errors when you try to configure SharePoint (voice of experience here)

Recently I had the possibility to work on some multi-touch stuffs using the .NET wrappers for the touch APIs included in Windows 7 RC. Do you remember Simon ?

John Papa has a tip on how to save some time and prevent Visual Studio to open your XAML files in preview mode . If you work with Silverlight a lot like I do, you might be frustrated with the time it takes Visual Studio to try to render the preview of your Silverlight Views. This can be a painful process, especially when the View gets more complicated … because sometimes Visual Studio cannot even display the preview. Also, whenever the XAML page is opened in Visual Studio, it takes a wh
