What's new in ASP.Net 4.5 and VS 2012 - part 1

I have downloaded .Net framework 4.5 and Visual Studio 2012 since it was released to MSDN subscribers on the 15th of August.For people that do not know about that yet please have a look at Jason Zander's excellent blog post .

Since then I have been investigating the many new features that have been introduced in this release.In this post I will be looking into new features available in ASP.Net 4.5 and VS 2012.

In order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 2012 using this link.

My machine runs on Windows 8 and Visual Studio 2012 works just fine.

Please find all my posts regarding VS 2012, here .

Well I have not exactly kept my promise for writing short blog posts, so I will try to keep this one short.


1) Launch VS 2012 and create a new Web Forms application by going to File - >New Web Site - > ASP.Net Web Forms Site.

2) Choose an appropriate name for your web site.

3) Build and run your site (CTRL+F5). Then go to View - > Source to see the HTML markup (Javascript e.t.c) that is rendered through the browser.

You will see that the ASP.Net team has done a good job to make the markup cleaner and more readable. The ViewState size is significantly smaller compared to its size to earlier versions.

Have a look at the picture below


4) Another thing that you must notice is that the new template makes good use of HTML 5 elements.When you view the application through the browser and then go to View Page Source you will see HTML 5 elements like nav,header,section.

Have a look at the picture below


5) In VS 2012 we can browse with multiple browsers. There is a very handy dropdown that shows all the browsers available for viewing the website.

Have a look at the picture below


When I select the option Browse With... I see another window and I can select any of the installed browsers I want and also set the default browser.

Have a look at the picture below


When I click Browse, all the selected browsers fire up and I can view the website in all of them.

There will be more posts soon looking into new features of ASP.Net 4.5 and VS 2012

Hope it helps!!!
