ASP.NET 4.5 새 기능

모델 바인딩이 특히 맘에든다. asp.net 4에서는 MVC3에만 있어서 아쉬웠는데.
그리고 나도 한때에는 웹폼을 혐오했는데, 웹폼의 생산성만큼은 이제 인정해야 할 듯.

The following table lists some of the enhancements that have been made for Web Forms in ASP.NET 4.5.
Feature
Description
Resources
Model binders
Web Forms now supports model binding, which lets you bind data controls directly to data-access methods. ASP.NET automatically converts data from form fields, query strings, cookies, session state, and view state into method parameters. You can use these parameters to select data from or make updates to the database. (This technique is similar to model binding in ASP.NET MVC.)
Model Binding and Web Forms (tutorial series)

Strongly typed binding expressions in data controls
You can now write strongly typed, two-way data-binding expressions in Web Forms data controls, instead of using Bind or Eval expressions. This approach lets you access complex properties in data controls. These expressions can be used with the new model binding feature.
Strongly typed data controls (What's New whitepaper)
Unobtrusive JavaScript for client-side validation
Unobtrusive validation moves the code for client-side validation into a single external JavaScript file, which makes pages smaller and faster to load. It also provides better caching of script files.
Unobtrusive Validation(What's New whitepaper)
HTML encoded data-binding expressions
New syntax lets you encode HTML output in page markup.
Fallback support for content distribution networks (CDNs) in the ScriptManagercontrol
When you set the EnableCdn property of the ScriptManager control, the control tests whether the script was loaded successfully from the CDN. If not, the control falls back to loading the script from an alternate (local) location.
Support for HTML5 form types
You can use HTML5 elements like email, tel, url, and search in Web Forms pages.
HTML5 Updates (What's New whitepaper)
Improved paging in the GridView control
The new AllowCustomPaging and VirtualItemCount properties of the GridView control let you customize paging functionality. These new properties remove the need for the control to retrieve all rows from the data source each time a new page is displayed.
AllowCustomPaging(MSDN Library)
VirtualItemCount (MSDN Library)
Enhancements to Web Forms compilation
The following improvements extend the Web Forms compilation system:
- A new ControlBuilderInterceptor class lets you customize Web Forms page and control compilation output.
- A new TemplateParser.ParseTemplate method lets you generate an ITemplate instance from a string of ASPX markup.
ParseTemplate (MSDN Library)
ITemplate (MSDN Library)

Alternative to IValueConvert, QuickConverter

https://quickconverter.codeplex.com/ Quick Setup Steps Add the assembly reference to your project. This can also easily be done using  the NuGet package . Add the namespaces to Quick Converter that it will need to know about (before any xaml that uses it is loaded). e.g. In your WPF application's App.xaml.cs file: public   partial   class   App  :  Application { public  App() :  base () { // Setup Quick Converter. // Add the System namespace so we can use primitive types (i.e. int, etc.). QuickConverter. EquationTokenizer .AddNamespace( typeof ( object )); // Add the System.Windows namespace so we can use Visibility.Collapsed, etc. QuickConverter. EquationTokenizer .AddNamespace( typeof (System.Windows. Visibility )); } } Add the Quick Converter namespace to your xaml files so you can ref...
