The HtmlHelpers are today closed for modification since they are static classes. There is probably not a way around that.

You can however define some interfaces which you resolve through the DependencyResolver so that we can modify the generated HTML. By doing so we can adjust the HTML outputted to fit our own needs.

I describe a similar approach here: http://blog.gauffin.org/2011/10/first-draft-of-my-alternative-html-helpers/

Add please native support for Stylus - much better than Less and SASS/SCSS CSS preprocessor.

Add significant TypeScript support if MS is serious about it. A nice start would be "Paste JSON as TypeScript Class/Interface"

common and cool controls where it's really easy to use such as http://awesome.codeplex.com and report viewer control for asp.net mvc

For example, you could add modifiers specifying that a method only compiles if the generic arguments do not implement iEnumerable

Need to have tools that gives interface like an app on tablet. Need something that connects asynchronous to server and give the users a rich experience like an win app or something like that. The 3rd party tools can be adopted to next framework as well.

In VB, if you have the line IF A = B THEN C = D and the line is split after THEN the C=D statement should be contained between the IF and the END IF

Desired result:
IF A = B THEN
C = D
END IF

Current result VS2012:
IF A = B THEN
END IF
C = D

It's good to add XML comments to methods and classes. Especially for intellisence reasons but while reading a piece of code I think it's waste of screen space. Makes it harder to navigate the code. It would be great if I had the opportunity to have it always collapsed. Maybe with a symbol next to the method where I can hover the comment.

Same goes for attributes. I want to see that there are some, but not the details.

I created an experiment to show how this could work a while ago here... https://github.com/atlascode/asyncsections

asp.net membership database schema, change uniqueidentifier datatype of primary keys to int fo all tables.

How i can redirect 301 www to non-www. I have tried to edit default.aspx, global.asax, web.config but server always responses error.

A control that works very much like the grid view but allows you to view content in a tiled view (eg. at least 3 or 4 columns of content on each row. sort of like the way you see in folder)

Make ASP.NET Bundling & Minification (System.Web.Optimization) using the virtual file system to support bundling and minification of virtual files.

I'd like to see a GUI for some MSBuild/Web Publish Target settings like: folder permissions (ACLs), blocking a folder from being overridden (e.g. upload folder containing user files), easy site backup before publish (to a zip file probably), etc.
