A High-Value, Undocumented LESS Editor Feature in Visual Studio
Recently a very valuable, undocumented feature in the Visual Studio LESS editor came to my attention. This applies equally to Visual Studio 2012 Update 2 and later, and to Visual Studio 2013. The installation of Web Essentials is not required to benefit from this feature.The Visual Studio LESS Editor respects @import statements, and can resolve namespace, mixin and variable definitions from imported files. However, a common pattern with larger LESS projects is to have one include file establishing the include order, and a large number of source files with no @imports at all. The BootStrap project, for example, co...
Introducing batch support in Web API and Web API OData
With the release of Microsoft ASP.NET Web API 2 OData, we have introduced support for batching requests. Batching is a web API feature that allows a customer to pack several API requests and send them to the web API service in one HTTP request and receive a single HTTP response with the response to all their requests. This way, the client can optimize calls to the server and improve the scalability of its service. For a more in depth look at the batch support, you can take a look at the specification. Batch in Web API In order to start using batch in Web API, the only requirement is to register a route w...

Tips When Making Changes in Entity Framework Code First Models after Scaffolding
When you scaffold an existing Entity Framework model, using MVC5 scaffolding in Visual Studio 2013, you can easily run into the issue of “The model backing the <DbContextName> context has changed since the database was created” as shown below. For example, in an MVC project, add the following model. Scaffold the Product model using “MVC 5 Controller with views, using Entity Framework” scaffolder in Visual Studio 2013. View the generated pages, Index/Edit/Details/Create, to verify things are working properly. Now, suppose we need to modify the Product model to add more fields, like Description ...

Web publishing updates for app offline and usechecksum
In Visual Studio 2013 we have added a couple of small features for web publishing that I’d like to share with you. Those updates are; how to take your app offline during publishing and how you can update the default file compare option. App offline support In Visual Studio when you publish your web application we do not force the remote app to be stopped/restarted. Based on your publishing artifacts your site may end up being restarted (for example you change web.config) but Visual Studio never had a way to take your application offline during a publish operation. There are a lot of reasons why you may want to...
Sending a CORS Request in IE
From the time we added CORS support for ASP.NET WEB API, we have seen many questions on its usage, including questions about sending cross-origin requests (CORS) from IE. IE 10 and higher fully support using XMLHttpRequest to send cross-origin requests. CORS for XHR in IE10 is a great blog post on this approach.CORS is also supported in IE 8/9, however, in a different way. Instead of XMLHttpRequest, an XDocumentRequest object is used to send cross-origin requests. Here’s another good reading about it: http://blogs.msdn.com/b/ieinternals/archive/2010/05/13/xdomainrequest-restrictions-limitati...
