Add-on Platform on ASP.Net web application

I want to create a web application using ASP.Net having an add-on platform, the system should be able to add add-ons on the fly (add add-ons dynamically) and make them available in the system.

Example: Upload a zip file (containing the code and any files required by the add-on) through a web form, when submitted the add-on can be used in the system.

I made some research but I couldn’t find a secure and with good practise example which implements an add-on platform using ASP.Net. I was wandering if any knows about a technique/technology which I can use or any leads which may help me with my research.

Any help would be ap开发者_开发知识库preciated, thanks.

Probably your best bet is Orchard, the new Microsoft CMS. It's an open source project based on ASP.NET MVC with an add-on framework. If you're thinking of WebForms rather than MVC, try DotNetNuke or Umbraco, both of which are also open source CMS's with add-on capabilities (though Umbraco is in fact transitioning to MVC in the next version).
