I believe many of my friends have recently encountered the bug that the vs version is too low when installing Silverlight 3 tools for vs SP1.
After two days, I finally got it done. The method is actually very simple: Do not download the tools installation package separately, but download and install it through Microsoft's web platform installer. The specific reason is unknown. From the process of installation, the cleaning tool running Silverlight 3 beta during installation may be due to the previous installation of sl3beta, although all previous versions have been uninstalled before the official version is installed, it is estimated that the uninstallation is incomplete. The specific reason cannot be copied. In short, this is a solution. We can try to install it through web platform installer 2.0 RC. The installation took a long time. It took me about an hour to prompt that the installation was complete. There was no change in the middle. I thought it had crashed several times. Now, we can continue happy Silverlight, and I will start my Silverlight journey.
