Click Once

Microsoft's latest attempt, .NET 2.0's ClickOnce technology, is meant to provide the benefits of HTTP-based application deployment while addressing the issues with NTD(No Touch Deployment which was issued in .NET 1.xx).
ClickOnce provides for HTTP-based application deployment of both locally installed applications which can be utilized as offiline or online and its application is on the Start menu and in the Add or Remove Programs Control Panel. And another option is online-only applications that feel like web applications in that they are only available inside the browser.
Other features such as security, authentication, file/io permission, and other permissions(Temporary Key .pfx) can be easily handled by VS2005.
