How does VS determine which version of Razor engine to use when editing razor webpage files
In VS2013 Preview, we released new Razor V3 runtime and design time Engine to support MVC5 and Razor V3 website’s runtime and design time behavior. Unlike Razor V2 runtime and design time, VS2013 did not GAC these binaries. Instead, the binaries are installed in the project bin folder when corresponding NuGet package is installed, and in “%ProgramFiles (x86)%\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\Web\Razor\v3.0” to support design time. As in VS2012 to determine which razor v1/v2 design time dlls to load, VS 2013 preview first use web.config file key <add key="web...

The $expand operator allows a client to retri...
Understanding OWIN Forms authentication in MVC 5
Overview The new security feature design for MVC 5 is based on OWIN authentication middleware. The benefit for it is that security feature can be shared by other components that can be hosted on OWIN. Since the Katana team did a great effort to support the OWIN integrated pipeline in ASP.NET, it can also secure apps hosted on IIS, including ASP.NET MVC, Web API, Web Form. Forms authentication uses an application ticket that represents user's identity and keeps it inside user agent's cookie. When user first accesses a resource requiring authorization, it will redirect user to login page. After the user provides ...
Manage CORS policy dynamically
Brief We introduced CORS support in ASP.NET Web API a few months ago. Out of the box it supports configuring CORS policy by attributes. It is a very intuitive and powerful way but lacks flexibility at runtime. Imaging your service allows a 3rd party to consume your service. You need the capability of updating the allowing origins list without compiling and deploying your service each time the list changes. In following this article, I show you two examples of dynamically managing your CORS policy. Prerequisites Set up the test environment CORS Service Create a WebAPI project. It co...

Browser Link feature in Visual Studio Preview 2013
Browser Link is just a channel between your Visual Studio IDE and any open browser. This will allow dynamic data exchange between your web application and Visual Studio. This feature is enabled by default in Visual Studio 2013 Preview. When Browser Link is enabled we register an HTTPModule with ASP.NET, which will then inject a <script> reference to every page request from the server. It is this JavaScript that does the magic of connecting the browser to Visual Studio. For Preview, we have a feature called the “Refresh Linked Browsers” that makes use of this channel between browsers and IDE. Because the b...
