AbhijitJana.net & AbhishekSur.com
6. Multi targeting
Key Notes :
Multi-Targeting Support in VS 2008
Changes in Multi-Targeting in 2010
Convert ASP.NET application from
one framework to another
framework
7. Different Version of Integrated Web Server
Key Notes
Visual studio used Integrated
ASP.NET engine to run ASP.NET
Application from IDE
CLR version (CLR 2 and CLR 4) you
have separate built-in ASP.NET
Engine
Side by Side Execution of different
framework
8. Code Snippets for Web designer
Key Notes
Code snippets for
– ASP.NET
– HTML
– ASP.NET AJAX
– XML
– ASP.NET MVC
Use Surround With Snippets
Custom Code Snippet
9. Java script intellesence
Key Notes
Improvement like Code snippets in
ASP.NET
Recognize dynamically generated
objects
10. Project Templates
Key Notes
Addition of new templates and
modification of existing templates
– ASP.NET Empty Web Application
– ASP.NET Web Application
11. Publish a web application
Key Notes
• Many New features added
for Web Site deployment in
VS 2010
• One-click publishing
• Web packaging
• Web.config transformation
• Database deployment
16. RadioButtonList and Checkbox List
Key Notes
Checkbox list and radiobutton list both
having “RepeatLayout “ properties
ASP.NET 3.5 supports “Flow” and “Table”
layout
ASP.NET 4.0 added two new layout
“Orderedlist” “UnorderedList
These layout has only “Vertical”
RepeatDirection for new layouts.
17. CSS Friendly Menu Control
Key Notes
ASP.NET Menu Control till Version 3.5
rendered as TABLE, TR, TD
New Addition of “Rendering Mode”
properties
Three Type of Render
Default
List
Table
18. Enhancement in List view control
Key Notes
Enhancement for layouts rendering
ASP.NET 3.5 needs a place holder
inside LayoutTemplate
ASP.NET 4.0 Listview doesn’t need
any LayoutTemplate
AbhijitJana.net & AbhishekSur.com
23. Meta Description
Key Notes
Search Engine looks for Meta tag of our
web page to get the details of page
contents
Two New Properties for Page Class
– MetaDescription
– MetaKeywords
These can be defined from both code
behind and from aspx page
Makes it easier to work with these than
defining with HtmlMeta.
24. Permanent Redirection
Key Notes
Removes the problem of Temporary
redirection (302) using Response.Redirect
and ensures Search engine updates its
database about this redirection using
Response.RedirectParmanent(301).
As the round trips will be minimized due
to ParmanentRedirection, Page rank can
be increased in Search Engines.
25. Web Form Routing
Key Notes
ASP.NET MVC 2 introduces Routing features
in .NET Framework 3.5 SP1.
Route Module is been added to
System.Web.dll so it is available readily to
any application.
ASP.NET 4.0 already implemented of
IRouteHandler called PageRouteHandler, so
we do not need to implement the same.
You need to register routes in global.asax or
any custom module. Once you register, the
routing will be available instantly.
RouteData is available from any page to
access RouteTable.
Response.RedirectToRoute allows to use
Route redirection from one page to another
by calling either routeName of routeValues.
Support for Expression to generate RouteUrl
30. Compression Enabled Session
Key Notes
Session Mode
– In Process
– Out Process
compressionEnabled attributes for
Session State
compress / Decompress the session data
during serialization / deserialzation of
session data
System.IO.Compression.GZStream
31. Better Control in View State
Key Notes
“EnableViewState” Properties for both
Page Level and Server Control
Page Level view state control treat as
highest priorities.
ASP.NET 4.0 Introduced ViewStateMode
– Enabled
– Disabled
– Inherit

32. Output Cache ProviderOutput Cache Provider
Extensibility in Output Caching
Key Notes
Till ASP.NET 3.5 System.Web.dll assembly
for caching
ASP.NET 4.0 introduced
System.Runtime.Caching.dll assembly for
caching
Supports Custom Cache Implementation
In memory Cache Implementation
System.Runtime.Caching.MemoryCache
Both object caching and ASP.NET output
caching will be pluggable
Using Sytem.Cache namespaces
Disk

37. Smaller Web.config
Key Notes
Grown considerably over time as ASP.NET
adds up features from 2.0.
In 4.0 major portion of Web.config is
moved to machine.config and all the
applications automatically inherits them.
Which means smaller web.config just
shown in the figure.
38. Performance Monitoring
Key Notes
Performance monitoring of a single
application running under one worker
process is difficult.
ASP.NET 4.0 allows you to configure
ResourceMonitoring enabled from
aspnet.config (Not web.config).
Managed Processor time and Managed
Memory used can be checked from
application performance option.
39. Auto Start Application
Key Notes
Huge load of initialization weak up asp.net
application for first web call.
IIS 7.5 introduces Application warm up
module to ensure your application always
keep running.
You can use applicationhost.config to
configure your IIS worker process to keep
warm up module in action
You can have managed hooks to the
system to write your custom code during
initialization using
IProcessHostPreloadClient interface which
will be called automatically before any
HTTP request is processed.
40. Web.config Transformation
Key Notes
Separate Web.config files for Debug,
release, staging etc.
Xdt:Transform and xdt:Locator lets you to
match certain portion of your config and
allow automatic transformation of
web.config.
Locator can be specified using XPath,
Match, Condition allow you to find in
config easily.
Transform includes Replace, Insert,
InsertBefore, InsertAfter, Remove,
RemoveAll etc.
41. Increases URL length
Key Notes
Previous static length of url to 260 characters (based on
NTFS file path limit) can be configured from application.
You can change the maximum size of URL using
HttpRuntime configuration.
requestPathInvalidChars lets you to prevent characters
in URL.
Support for URL in different browsers:
1. 2083 characters for IE with less than 2048 characters
in path portion of the url.
2. More than 100,000 characters are supported for
Firefox but address bar can only display upto 65,536
characters.
3. 80,000 for Safari.
4. 190,000 characters for Opera
Still it is not recommended to use more than 2000
characters in URL
42. WebPackaging & Publishing
Key Notes
VS 2010 allows you to publish your application with a
single click.
MSDeploy Publising, FTP, File System, FrontPage Server
Extensions.
Packaging allows you to package your web application
into a compressed archive, which you later may use to
deploy the application.
Allows you to deploy Files, Settings, Configuration, GAC,
etc.
Sql Server deployment allows you to include SQL Scripts
with your package.
46. Client Side Improvement
Control over Client ID
HTML Encoded Code Expression
CSS Improvements
AbhijitJana.net & AbhishekSur.com
47. Control over Client ID
Key Notes
All Server side control rendered as HTML
Control and need a ID to identify.
This ID used to be auto generated
New property introduced “ClientIDMode”
Control.ClientIdMode
– AutoID
– Static
– Predictable
– Inherit
48. HTML Encoded Code Expression
Key Notes
Till ASP.NET 3.5 we have used <
%=expression%>
– Causes XSS
ASP.NET 4 introduces the following new
syntax for code expressions.
– <%: expression %>
– <%=
HttpUtility.HtmlEncode(expre
ssion) %>
<%: expression %><%: expression %>
<%= HttpUtility.HtmlEncode(expression) %><%= HttpUtility.HtmlEncode(expression) %>
49. CSS Improvements
Key Notes
VS 2010 has been updated to improve CSS
2.1 Standards.
ASP.NET 4 has been to help render HTML
that is compliant with the latest HTML
standards
Use of
controlRenderingCompatibilityVersion
Default set to 4.0 for ASP.NET 4.0
applications
We can use 3.5 to support legacy markup
53. Overview of Dynamic Data
Creates UI automatically that reacts on
data.
Pages are created dynamically based on
Data configured for the web site.
Linked pages holds relationship between
data.
Support for both Linq to Sql and ADO.NET
Data Entities.
