The Identity and Access Tool for Visual Studio 2012 enables you to secure your application with claims based identity and accept users from multiple identity providers.
This extension adds a context sensitive project menu entry to easily add identity capabilities to your Web Applications, MVC Applications and WCF Services. This will provide you with capabilities for developing and testing your application with a Local Development STS, connecting to a corporate identity provider like ADFS2 and using the Windows Azure Access Control Service to connect to other identity provides such as LiveID, Google, Yahoo and Facebook. It does this by updating your web.config file with the proper settings to enable the Windows Identity Foundation in .NET 4.5 and adding the necessary configuration for the identity provider you select.
Installing the Extension
If you are using the Local Development STS you can set additional claim types and values, SAML token formats, or customize the port number on the Local Development STS tab.
You can make additional changes to identity configuration in your web.config on the Configuration tab on subsequent runs of the tool.
