How to get ClientContext

Question

I want to get clientcontext in a visual sandbox webpart.

How can I do it without providing any credentials for url, as webpart will be on home page. I don't want to provide any credentials either, just want it to work like, SPContext.current....

string siteURL=”http://localhost“;
ClientContext clientContext = new ClientContext(siteUrl);

Answer 1

Try to use: ClaimClientContext.GetAuthenticatedContext, instead of new ClientContext
