Razor based pages need a design surface in the same way as ASP.Net Forms pages or straight HTML. This should support dropping of controls onto the page, dragging of margins and padding, and all the other features we have normally in design view.

As projects grow and transition from greenfield to brownfield projects .config files are getting more and more obsolete and dead stuff in them.

Do help me and show me what I delete of this.

Today it's impossible to fully localize the view models / validations without using hacks or clutter the view models with the ErrorResourceName etc.

It would be a lot easier to handle localization if you created an extension point where one could register custom string providers.

Something like:

LocalizationStringProvider.Clear();
LocalizationStringProvider.Add(new MySqlProvider());

Can you add IntelliSense support for CSS selectors in stylesheets?

You can autocomplete all HTML tag names, all pseudo-classes (preferably with parameter hints) and pseudo-elements, and all IDs and classes that appear in other selectors in that or other stylesheets.

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

The ability to specify multiple web.config Transforms; all of them applies and final web.config gets created out of them. And then couple of item templates to add specific transform...e-g

web.config
release-ajax-transform
release-dynamic-data-transform
debug-ajax-transform
debug-dynamic-data-transform

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

I want to be able to specify that a ContentPlaceholder should contain JavaScript or css, and get intellesense/syntax highlighting in the placeholder.

Make a web version of Visual Studio that opens solutions and projects from a cloud-based source control, compiles and deploys my applications to Azure, an environment I can access anywhere from any browser.

I'd like to create user controls in ascx form in a library and use in a website or web project

Right now when you have a 64 bit Web project in Visual Studio 2012 it will always launch the iis express 32 bit version. Can we make Visual studio smarter depending on the platform on what iis express to load. Or at least allow for us to change that path inside the csproj file?

Add more sql db support (mysql, postgresql)

Why not use for *.ts the same mechanism used for compiling *.ascx and *.aspx to DLLs? There is a whole infrastructure of build providers that can be utilized for this purpose. If compilation of TypeScript sources get implemented as a build provider, it will work even without Visual Studio, with any editor.

right now you have to run aspnet_regiis to encrypt the connection strings in a web.config. It would be nice to this could be built in as a part of the deploy process.

It would be great if Sharepoint supports MVC natively/out of box!

We shouldn't have to download the votive stuff manually - WiX deserves the extra exposure that automatic inclusion would give it.

The injection of controllers work with MEF

Libraries like Require.js help to structure the javascript files into modules that are resolved on runtime or can be passed to an optimizer that bundles all javascript files into on file with the correct order.
It would be cool to have support in ASP.NET and Visual Studio for these concept and that it would be included in the Bundling and Minification Process.
And Intellisens should not break when using require.js.
