Sandbox architecture in ASP.NET?

Question

Is it possible to develop a web-app in ASP.NET (framework is not a constraint), to have a sandbox architecture, and deploy widgets without disturbing the parent application?

I expect both the parent application and the widget to be developed using .NET.

EDIT: To elaborate, I want to have an web-app, say App1, and widgets (say wid1 and wid2). wid1 and wid2 should be like a plugin into App1, only difference is that, if I make any changes to wid1, I want to be able to deploy it without disturbing App1 or Wid2. The widgets can be something similar to a flash object, only that it needs to be developed on .net.

I believe you will want to look into Application Pools. In a web server running IIS with ASP.NET websites, you can create Application Pools which will contain your applications (web sites). You can restrict pools to limit resources usage like RAM, CPU, # of threads, etc. If one of the websites go crazy, it should only affect it's own Application Pool. You can put more than one website in a single Application Pool so if you put all of the websites in one Application Pool, then they will all crash together.

Would something like the Managed Extensibility Framework be what you are looking for? They even have a WebForms sample:- http://mef.codeplex.com/releases/view/44166
