1. Make sure that Visual Studio 2010 is installed on your computer.
2. download the latest Silverlight SDK and Silverlight tools (http://www.microsoft.com/getsilverlight/get-started/install/), and follow the prompts to install correctly.
3. After completing these preparations, you have configured the Basic Environment for running Silverlight.
(Note: problems that may occur when running vs2010 after installation:"Unable to start debugging -- The Silverlight developer Runtime is not installed. Install a matching version ")
Solution changeThe problem is that there is no way to start debugging. After Google, we found that the Silverlight and Silverlight SDK were deleted in the control panel, and then the problem can be solved by re-installing the Silverlight tool.
The cause of this problem may be the version during installation. If this problem occurs, uninstall it and then download the new version.
This problem is also caused by Silverlight SDK and Silverlight tools installation errors. By default, Silverlight is installed in version 3.0 in vs2010.
