ASP.NET MVC ASP.NET Web Pages WebMatrix

Some people have questioned the security of the ASP.NET SimpleMembershipProvider's storage of passwords. The cause for concern seems to stem from the fact that the PasswordSalt field in the standard membership table is unused by the SimpleMembershipProvider, whereas it is used by, for example, SqlMembershipProvider. So what is the PasswordSalt field, and why should the fact that it isn't used raise an eyebrow?

HTML5 Form Helpers For WebMatrix

Extension Method ASP.NET Web Pages WebMatrix HTML5

It's an odd thing: WebMatrix 2 is lauded for its support of HTML5, but the Web Pages framework doesn't include any helpers for the new HTML5 form input types such as email or color. It's fair to say that support among browsers for the new inputs is patchy at the moment, but with barely a week flying past without a new version of one or other browser being released, it won't take long for that to change. So in the meantime, if you prefer to use helpers, you have to write your own for rendering HTML5 forms.

Cannot use a lambda expression as an argument to a dynamically dispatched operation

Since the introduction of the Web Pages framework, ASP.NET has been making use of the dynamic type introduced in C# 4.0. Along with that comes some new error messages which at first glance don't make a lot of sense - mainly because they are unexpected. I have already looked at how dynamics do not support extension methods, and a recent question in the ASP.NET forums illustrated another way in which the dynamic type can catch you out.

ASP.NET Web Pages WebMatrix

ASP.NET 4.5 saw the introduction of new features for improving the performance of web sites. Delivered within a new library called System.Web.Optimization, bundling and minification enables you to combine multiple JavaScript or CSS files into one bundle, and to minify them thereby reducing the number of HTTP requests that browsers have to make, reducing the size of the files, and improving performance of the site overall, especially over slower (read 3G) networks.

WebMatrix - jQuery Cascading Dropdown Lists

jQuery ASP.NET Web Pages WebMatrix

I have looked at cascading dropdown lists with WebMatrix previously, but the approach I featured demonstrated the use of jQuery Templates. At the time, the jQuery Templates project looked promising, but since then, the jQuery team have decided not to take them beyond beta stage. So the reason for this article is to illustrate a more "traditional" jQuery approach to managing cascading dropdown lists when developing ASP.NET Web Pages using WebMatrix.
