In Visual Studio 2012, you had the Identity and Access tool which gave you an easy way to configure your WIF configuration and integrate with an existing STS.
After installing Visual Studio 2013, I started looking on the Visual Studio Gallery for a new version of the tool. But no luck, only a VS 2012 version was available . And it seems that a version for Visual Studio 2013 will never appear.
Vittorio Bertocci shared the following information:
In VS2013 Microsoft added support for claims-based identity directly into the ASP.NET project creation experience (see http://blogs.technet.com/b/ad/archive/2013/06/26/improved-windows-azure-active-directory-integration-with-asp-net-amp-visual-studio.aspx ), hence there are no plans of porting the Identity and Access tool to VS2013. We are aware of the fact that as of today the feature set of the two approaches are not 100% equivalent. VS2012 and VS2013 work well side by side, if you depend on functionality only available on the Identity & Access tool we recommend you keep both available until functional parity is reached (see below).
Here there are some comments on the main differences:
- Re-entrancy: Right now VS2013 can configure authentication only at project creation time. Re-entrancy is being considered as a feature for a future update
- ACS support: As detailed in http://blogs.technet.com/b/ad/archive/2013/06/22/azure-active-directory-is-the-future-of-acs.aspx , ACS will not receive further investments hence VS2013 will not support it directly. AS equivalent ACS functionality appears in Windows Azure AD, VS2013 will expose it accordingly
- Local STS: Support for Local STS didn't make it in VS2013. There are community driven alternatives (see http://brockallen.com/2013/10/22/announcing-thinktecture-embeddedsts-a-simple-local-sts-for-asp-net-applications/).
