Vsi Builder is an extension for Visual Studio 2012 which allows packaging code snippets and add-ins into the old-style .Vsi packages, since they cannot be deployed via the new VSIX format. You simply add a list of additional contents, like snippets and add-ins, and then you build your redistributable .Vsi installer. With Vsi Builder you can
1.package, deploy and share Code Snippets and Visual Studio add-ins (not extensions) who are not supported by the VSIX format 2.add End User License Agreement to the packages 3.add a digital signature whenever you own a digital certificate 4.uninstall previously installed contents
