currently WPF doesn't support RTL, please add it in your comming applications...

Add additional data types that implement quad precision IEEE 754-2008 numbers

The Group object from the Regex library needs a Name property. I am in a situation where I have regexes that are not known at compile time being run, and I need to create a Name-Value pair from the resulting matches. This is very difficult without a Name property.

i think it's time to add grid to print in your in your ide for database application. i am the programer in oranus novin co. we created a roubust and powerfull grid to print . with it your customer can easily create and customize many reports in a couple of minute.
and your programers can add this great functionality with adding just a couple lines of code.
you can gift your customers this great tool and save thousands of hours and days of programers all over the world

Many times it would be nice to provide simple local database functionality that is separated from much larger database instances. For these situations you need to get the latest version of the runtime and include it as yet another requirement for deployment across environment. Depending on the situation in which this is being suggested, the fact that it is not part of the .net framework can sometime be a limiting factor to its use.

The class NotifyCollectionChangedEventArgs has 11 constructors, dealing with add, remove, replace, move, and reset actions, and single or multiple changed items.

I think we can create 5 static facotry methods, for example,
NotifyCollectionChangedEventArgs.CreateAdd(IList)
NotifyCollectionChangedEventArgs.CreateAdd(object)
NotifyCollectionChangedEventArgs.CreateAdd(IList,int index)
etc.

NotifyCollectionChangedEventArgs.CreateRemove(IList)
...

I think with these facotry method, we can create our desipred instance quickly.

I find myself often writing something like this, when I'm working with URI's:

string host = "http://host.com/"; // Or some other host
string page = "folder/page.html"; // Or some other page - f.ex. a crawler
Uri targetUri = new Uri(new Uri(host), page);

This is because Uri doesn't have a constructor that takes two strings and does this for me. I'd like for URI to have a new constructor, which can take two strings, and basically do the above (or something smarter).

in datagridviews have the (Name) be loaded into intellisence

For example dgv.(name) in the following:
For Each row As DataGridViewRow In dgv.Rows
If (row.Cells(dgv.(name))) = "test" Then
row.(name2) = ""
End If
'MessageBox.Show(CStr(row.Cells(dgv.(name)).FormattedValue))
Next row

There doesn't appear to be a way of retrieving the generic parameter constraints on a GenericTypeParmeterBuilder that you didn't create.

Please override GetGenericParameterConstraints to return the constraints.

Setting enabled=false of a panel current sets child textboxes to enabled=false, but not validators. Would probably make sense to set enabled=false to ALL controls within a parent panel (if the panel is set to enabled=false).

Provide an interface like

public interface IParsable<T>
{
T Parse(String)
Boolean TryParse(String, out T result)
}

so it is possible to write more generic parser logic.

In order to build a c++ project with .Net 2.0 VS 2008 SP1 must be installed. It would be nice if that could be avoided.

The standard windows controls are very poor and most of them since NET 1.0 the same. For developing state of the art software developers must spend many time in creating user controls or buy 3rd party addons.

Currently QueueUserWorkItem and UnsafeQueueUserWorkItem allocate a small object on each queueing.
Add an overload that will be taking IExecutable so that using ThreadPool won't add pressure on GC.

IExecutable could look like this:

interface IExecutable
{
void Execute();
}

When I did some research about switching wallpapers programmatically on Windows 7, all posts said it's not possible right now because the API is not public.

I would suggest to add API functionality to switch wallpapers / wallpaper collections programmatically and to change the interval a background is changed, best in a more or less platform independant manner (from Windows XP to Windows 7/8).
