2. ASP.NET INTRODUCTION
 ASP.NET is a web development platform, which provides a
programming model, a comprehensive software infrastructure and
various services required to build up robust web applications for
PC, as well as mobile devices.
 ASP.NET is used to produce interactive, data-driven web
applications over the internet. It consists of a large number of
controls such as text boxes, buttons, and labels for assembling,
configuring, and manipulating code to create HTML pages.

the HTTP commands and policies to set a browser-to-
server bilateral communication and cooperation.
 ASP.NET is a part of Microsoft .NET platform. ASP.NET
applications are compiled codes, written using the
extensible and reusable components or objects present in
.NET framework. These codes can use the entire hierarchy
of classes in .NET framework.

7. 1 .Bundling and Minification Feature
 The newly introduced bundling and minification feature helps
to bundle and minimize the size of the scripts and style sheets
in your application.
 This feature has a great impact on the performance of your web
application as a whole. You now have a
System.Web.Optimization namespace that provides support for
bundling and Minification of files.
 Once you create a new project in ASP.NET 4.5, you'll notice
these lines in your Global.asax file:
protected void Application_Start()
{
//Some code
BundleTable.Bundles.RegisterTemplateBundles();
}

8. 2 . Strongly Typed Data Controls
 ASP.NET 4.5, have data controls that can be strongly typed, That
will get intellisense where user just need to assign the ItemType
property to a model that is going to be associated with the data
controls used in “.aspx” pages.
 Here is a snippet of code that illustrates how you can use this:
<asp:TemplateField HeaderText="Name" >
<ItemTemplate>
<%# Item.Name.ToString() %>
</ItemTemplate>
</asp:TemplateField>

9. 3 . Model Binding - Isolating the Web Form from the
Model
 The Model binding feature in ASP.NET 4.5 enables users to develop Web
forms, that are independent of the Model that populates the view.
 The biggest advantage of using Model Binding in ASP.NET is that the user
can easily unit test the methods.
 In ASP.NET 4.5 support for model binding is provided through the usage of
the ‘System.Web.ModelBinding’ namespace.
 This namespace contains value provider classes like ControlAttribute,
QueryStringAttribute, etc.
 All these classes are inherited from the ValueProviderSourceAttribute class.
