I chose this request because it is the actual request to retrieve data from the Server and pull it back to the Client. After the browser finishes refreshing, select the last HTTP request in the list (it should be last or close to last). You should see a bunch of HTTP requests appearing. This will start вЂњrecordingвЂќ all HTTP traffic.Д¤. Select the вЂњNetworkвЂќ tab and then click the вЂњStart CapturingвЂќ button.When IE launches, press F12 to open the Developer Tools.Press F5 to launch the LightSwitch HTML app.You can follow the steps on this animated gif: Now we can launch our app and use Internet ExplorerвЂ™s F12 Developer Tools to look at a particular HTTP request. Select the вЂњBrowse Data ScreenвЂќ template, and for the Screen Data just select some table that you know has data (IвЂ™m using a Customers table). Right click on the LightSwith HTML Project, and select вЂњAdd ScreenвЂ¦вЂќ We need some way to display the data, so letвЂ™s make a very simple screen around one of our database tables. Select which tables you want to import and click вЂњFinishвЂќ. Lets attach to some database that already has data in it (IвЂ™m attaching to a Northwind SQL Database, but if you donвЂ™t have that available, you can attach to the Northwind ODATA Service).

Launch Visual Studio and navigate to File вЂ“> Create New Project and select a LightSwitch HTML Application (the LightSwitch Desktop Application uses a Silverlight Client, which has actually already been using the JSON Light format since Visual Studio 2012 Update 2).ДЄfter youвЂ™ve done this, go ahead and click вЂњAttach to External DatabaseвЂќ. IвЂ™ve also made a simple animated gif that walks through these Design Time steps: If you arenвЂ™t familiar with making a LightSwitch project, please check out the very short tutorial on our Developer Center IвЂ™m going to walk through making a simple LightSwitch project. We can then use Internet ExplorerвЂ™s F12 Debugging Toolsto look at the size of the HTTP requests and response. The easiest way to demonstrate this is to create a simple LightSwitch application, attach to a database with data, create a simple screen, and then вЂњlaunchвЂќ our app. LetвЂ™s take a look at the bandwidth usage now, and get an idea of just how much less bandwidth is being used. As you might guess, this format uses considerably less bandwidth. With the release of Visual Studio 2013 RC, LightSwitch is now using a format often called JSON Light. Which as the name implies, used up a bit of bandwidth.

The LightSwitch HTML Client in previous releases was using a format of ODATA often called JSON Verbose. Some of these ways are more verbose than others, but fortunately for us the ODATA team at Microsoft recently worked on ways to make ODATA less verbose. ODATA can be formatted a few different ways. LightSwitch uses a REST-based protocol called ODATA for communication between the Client and the Server. LetвЂ™s take a look at what we did and how it can be useful to both developers and users of LightSwitch applications. With the release of Visual Studio 2013 RC, we on the LightSwitch Team have made some changes in how much bandwidth our HTML Client and Server use when communicating.
