Maintaining XML comments especially with code examples is a pain. It would be very useful if VS11 has built-in functionality for editing XML comments with a GUI addon. See DocumentX plugin for VS2010.

If we have to work on several solutions at same time, one thing that could help to improve our performance, is the possibility to open them all in the same VS instance.

You should be able to enter comment in the supported (C++,C#,F# etc) languages within the code just like ordinary comments but have some special way to mark that the comment contains mathematical notation/formulas that the IDE can interpret and display. It would be handy if you could copy formula from say Mathematica and then insert it into the comment.

Right now, the first thing I need to do after a search, is move the scrollbar on the search result to scroll the actual code into view.

If the searchresults are converted to a grid, I can just switch the columns, so that the information I am most often interested in, will be visible right away.

The "Find and Replace" window needs a "Skip File" button; I often find myself getting caught in compiled script files or dbml backends, etc. while looking for a term that should be easy to find with the exception of those few files that hold multiple uses of it.

maybe use/apply silverlight in the IDE. make the UI feel similar to a WPF, also include a new item datetime picker for asp.net or winforms/wpf/silverlight

It would be nice if folders in the solution explorer open automatically then i drag some files from my browser over it because sometimes there are subfolders in it there i want to drop my files in :-)
..after this action they could close (go back to the last state) automatically

I work on several projects but have three main ones. It's annoying when one falls of the recent projects menu because I've been doing other things recently. It'd be better if I could say that there are some that are always on the list.

One has to start the debugger to view a web page with IIS Express, which causes much of the IDE to become read-only, making it difficult to play with an app while making coding changes. When the debugger is stopped, the page can no longer be viewed in the browser. IIS does not have this issue since it is always available.

Like Windows OS, for VS vNext pl provide option to upgrade VS2010 to VS 2012 bcoz instlling/uninstlling VS is time consuming!

Make possible to Clean/Rebuild Web Site Project.

Currently Clean/Rebuild a solution containing Web Site performs the action against all the projects inside except web sites, nothing happens with them.

It will be great if the Visual studio will start your solution with standard design pattern template, or give you the capability to transform your code from one design pattern to another.

It will be great to create a web version of Visual studio that allow the developer to write code, compile and deploy from any machine , any where just by using Browser. The processing, compilation and deployment will be done on centralized server, but as user I can go to any IE, login, see the code, change code, debug code, deploy a code and test an app. If you think this is impossible then my question will be Why not?

Add a smart paste to the menu, so we can paste as a comment, as xml comment, as stringbuilder, etc...

Hosting web sites from the project folder is a terrible burden on developers.

Deploy all the files to the output path, just like with a desktop application project. For projects targeting IIS, deploy the files to the IIS website via the appropriate web services.

Any time a Visual Studio Development Server hooks up to a project, it should work a copy of the output folder. This prevents testing from modifying the project's or the output's web.config.

The first public version of Windows 8 seems to come out this autumn. Microsoft claimed ARM support. Can't imagine, why I need Windows on ARM without Visual Studio.

The Oslo M language tools look like a good dsl maker and would be a good addition. C++ proj template would be nice, too.

Add common images not only in *.png format but also in XAML, probably using DrawingImage
