Imporve x64 debugger so Edit and Contunue works when running on Windows x64 o/s

I want to able to see function return value in managed debugger just like unmanaged debuger (it has this feature from Visual Studio 6.0!).

In Visual Studio 2010 there is an MPI Cluster Debugger that allows us to debug MPI applications.
It seems that this feature has gone, so please bring it back to make it easier to develop MPI applications on Windows.

I would really like xaml debugger! I think that this caution is necessary! very difficult to find errors in the xaml.

Enable "Edit and Continue" when debugging silverlight projects.

It is very annoying and fells like the 20th century that you first have to stop debugging before you make any change to the code (or comments) and then have to restart the whole application.

When I'm debugging I look with different eyes at my code. It makes me wonder what things do and it would be a great time to add some comments to the code. Unluckily (while the executing code is not changed) I can not add comments and always have to remember where I wanted to add some extra comments,

Improve debugging support for Ix and Rx queries in the IDE. Specifically, a condensed call stack view that was more of a "query stack" would be great. It would also be great if we could hook into the "query stack" features from our own LINQ-based APIs.

Visual Studio debugger should support automatically debugging created child processes

Under the Debug Menu, add an Attach to IIS item. The new feature should detect the correct IIS process for the installed OS. This relieves the user from searching through the Attach to Process list to find aspnet_wp or w3wp.

If no sources are available, instead of showing x86 assembly, show .NET IL and allow to step through the IL instructions.

Add IntelliSence support or at least condition history picker

The "exceptions" Dialog isn't very usefull.
Somtimes i want to break on IOException somtimes on ArgumentException or a set of n other Exceptions. Everytime I have to open the Dialog serch for the Exceptions check them and close the dialog. Everytiem the same work.

It would be nice to have a "Save configuration as" Button in the Dialog to save the curretn configuration under a specific name. Later you can select a configuration via a submenu entry in the Debug-->Exceptions menu.

Currently Debug->Modules window doesn't allow neither to be filtered (e.g. by name and wildcard) or grouped (e.g. by process),
nor columns to be truly hidden (columns' width is decreased to 0 instead).

Under Linux reverse debugging of C++ code is possible for a while. Both by a commercial solution (UndoDB (http://undo-software.com/)) and meanwhile by GDB, too (http://www.gnu.org/s/gdb/news/reversible.html).

It's time to add this capability to the Visual Studio debugger, too.

When you're using TFS and want to run you application, hitting 'F5' could be a pain in the ***.
You'll have to right-click on you project>Debug>Start new instance.

A shortcut for that would come in handy for the startup project in your solution.

Shortcuts are the key to smooth working in my opinion.

Config transforms change behavior that should be easily testable.
Without this option either the web.config must be edited or the app must be published.
Please add an easy way to use a config transform during debug and test without changing the web.config itself. If the config file is changed, then it would be easy to accidentally commit those changes to source control.

Add support to watch expressions with getters (const functions) in C++

Examples:
1.
float GetWidth() const;
float GetHeight() const;

area = obj.GetWidth() * obj.GetHeight();

2.
const float operator[](unsigned int index) const;

val = obj1[i] + obj2[i+1];
