Authenticate users on my site through LinkedIn - linkedin

I'm working on a small site for my university. The requirements include the ability for our users to authenticate with their LinkedIn accounts. I know Facebook and Twitter have such capability, but what about LinkedIn? I'll be doing this in .NET, is there a native SDK?
Thanks,
Sara

LinkedIn uses OAuth just like Facebook, their developer site / docs are at:

I believe both of those providers support OpenID. While some people out there bash it, I know other sites that have used it with great success.
I would start by finding a good OpenID provider for .NET and go from there.

For this you use Twitter's OAuth authentication framework. It's used so that users don't have to directly enter their user + password into your site. (I assume you know how the front-end to that works already.)
You can use this little example to use OAuth from .NET - it is built for ASP.NET. (The demo the guy provides is My Tweeple.)
Twitter actually includes instructions for using OAuth to make a Facebook Connect-style system.
