“添加新项”选项中未显示“ Windows 7 Phone的Silverlight”选项

Question

I have downloaded and installed Microsoft Visual Studio 2010 Express for Windows 7 Phone. Problem is that i cant see "Silverlight for Windows Phone" option when I right click my Project name and select Add -> New Item option. I can only see "XNA Game Studio 4.0" under "Visual C#" category. I have tried installing Silverlight SDK separately by downloading it from Microsoft site but the installer tells me that i have already installed the newer version of the SDK. Due to this problem I can't use few Silverlight classes like ChildWindow etc.

Can anyone please help me in this regard?

Answer 1

I personally haven't had problems with the WP tools install, but I have witnessed others having problems. The only advice I can give is to uninstall all the tools, sdk, etc and reinstall with the latest.

It's a pain, but might be necessary unless someone has a better idea.

Answer 2

The instructions at http://msdn.microsoft.com/en-us/library/ff402526(v=VS.92).aspx say

Make sure you have downloaded and installed the Windows Phone Developer Tools from the App Hub.

So my advice is to make sure you've done that.

Answer 3

Right having just struggled with this myself I finally found an answer. If you have a Full version of Visual Studio installed it will not install the templates to the Phone version of C# express (turns out it is actually a different executable to the standard C# Express, go figure)

So to resolve this you need to do a couple of things:

Snippets

• First, add the path to the Snippets in the snippet Manager using "Tools -> Code Snippets Manager"
• Click on "Add" and enter the following Path:

C:\\Program Files (x86)\\Laurent Bugnion (GalaSoft)\\Mvvm Light Toolkit\\Snippets\\CSharp\\

(Note ignore the (x86) if you are on a 32bit system) This will install the installed snippets into VS Express.

Templates Now this is a little more tricky but bear with me

• Copy the MVVM folder from:

C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\\ProjectTemplates\\CSharp\\Silverlight\\

To

{Documents Folder}\\Visual Studio 2010\\Templates\\ProjectTemplates\\Visual C#\\

(Replacing the {Documents Folder} section with your My Documents folder)

• Repeat the above replacing ProjectTemplates with ItemTemplates

Finally!! To finish this off you have to tell VS Phone Express to actually install the templates

• Run a Command Prompt with administrative privileges (either create a command line short-cut on the desktop and right-click run it with admin privileges or use the VS tools command prompt)
• Run the Following command in that window

"c:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\\VPDExpress.exe" /installvstemplates

(Note ignore the (x86) if you are on a 32bit system) If all goes well you should see nothing happen :D, but if you run VS Express for Windows Phone now you will have the new templates installed and the item templates plus the all useful code snippets

Hope this helps!
