Question

What is the best way to use live id authentication with azure based asp.net mvc project?

I find the options 1) With in Live SDK, there are options like REST, JavaScript, C# etc. 2) Since my project will be hosted in azure, there is another way "Securing Web Applications with ACS" http://msdn.microsoft.com/en-us/library/gg185928.aspx

Please suggest the design and also support with pros when an particular approach is good.

Answer 1

You definitely want to work with ACS. Not only is it intended for this purpose, there's a fully worked up example at

which will give you a flying start.

ACS, and Windows Identity Foundation in general, lets you take the approach of separating identity verification from your application altogether. This saves a ton of code and means that you have much less "plumbing" to support.
