Securing sections in Web.Config
For ASP.Net applications, developers usually store lots of configuration data in the Web.Config, some of such settings can contain secured information such as connection strings, email settings, proxy settings etc. Storing credential information in Web.Config as plain text is a threat as this could lead to leak the information. Though the web server will not render web.config files to the visitors, you need to see there could be users, such as system administrators, back up operators, etc who have access to your server’s file system. Exposing secured information for such users is a threat and you need to protect your configuration data. The solution is to encrypt the sections in Web.Config and thankfully ASP.Net offers out of the box support for encrypting and decrypting the connection string placed inside Web.Config.
In this article I am going to demonstrate, how to encrypt/decrypt the connection string section in Web.Config, you can follow the same concepts to encrypt any other section in web.config. For the purpose of the article, I created an ASP.Net empty web application and added a default.aspx file. The project in solution explorer looks as follows.

JQuery is playing a major role in today’s client side development. As a developer you cannot stay away from these things, you need to adapt these. At the same time you cannot develop (at least not practical as cost/time wise) all those client side scripts, you need to depend on third party JQuery plug-ins to bring attractive user friendly interfaces. There are lots of plug-ins available over internet for free that allows to use in your website. If you are developing sites, you must be using use several plug-ins in your site.

Semantic Tags in HTML 5
In December 2012, W3C has published the complete definition of HTML 5 specification. Already most of the browser vendors have implemented support for HTML 5 and you can expect future versions of browsers will have complete support of the specification. In the introduction of HTML 5, web developers faced some challenges to support their markup in non-HTML 5 browsers. This added some cost to web development. Now web developers can expect better browser support and all the browser vendors already announced their commitment to this standard.

Using custom fonts in your web pages
From the start of web, people were restricted to use standard fonts(those are globally available in all platforms) such as Arial, Times etc, for displaying content in web pages. The main issue was that the browser did not have the capability to read the font from server. Due to this companies were forced to use different font than their branding for the web pages, which created dissatisfaction for the brand owners. Though internet explorer addressed this by allowing embedding font starting from version 4, there was no common method that works universally in all browsers. With HTML 5 specification, things are changing. HTML 5 have a @font-face element, that can be used to link your page with a font that resides in remote location.

When asp.net introduced the concept of viewstate, it changed the way how developers maintain the state for the controls in a web page.

Viewstate made allowed the developer to do it with ease. The developers are not bothered about how controls keep there state on post back.
