Use this package with ASP .NET in order to authenticate your users with Singly. By default singly access_token will be placed in the session with this name "singly_accesstoken". But since this NuGet package is just source code you can modify that and store it somewhere else (like a cookie if using SSL).
Once you get an access token you can call Singly API using OData and JSON light installing the latest tooling http://www.microsoft.com/en-us/download/details.aspx?id=34773 that supports the new format.
This is how queries look like to any service (twitter, facebook, foursquare, etc):
context.Statuses.Where(s => s.Data.Contains("@woloski")).ToArray();
You can query contacts, photos, videos, news, statuses, etc. More queries:
