Silverlight uses the sllauncher.exe tool to install, run, and uninstall out-of-browser applications. Additionally, Visual Studio 2010 uses this tool to run out-of-browser applications in emulation mode to enable debugging. You will not typically use this tool directly unless you need to perform these actions in custom scripts.
