In my opinion. string should be a struct which have only pointer and readonly length inside. Empty string should be automatically refer to null

string should not Nullable. null should be empty string automatically for disambiguous. so string should be struct with default value is Empty

OK, this is hard and very big impact to system

So I have another idea to let IsNullOrEmpty be extension method instead of static. Extension method can be used even object is null

Also other function of string should convert to extension method too. Same reason. And it should treat null string as empty string

I just came off a nasty situation where VS installation got hosed over a period of a year and half. I thought staying up to date with patches was a good thing, never realized it could hose the VS Setup completely. Details is in this forum post http://forums.asp.net/p/1772359/4850404.aspx/1?p=True&t=634657393972716075 .

End of the the Windows Update/Visual Studio Update/ASP.NET Update and other sub-component updates, ALL affect the basic Visual Studio setup. And affect it to a point where the original Visual Studio installer becomes completely useless for maintenance purposes. This needs to be improved/fixed. One way would be to build an installer that followed the XCopy deploy moto of .NET.

In Visual Studio IDE I would like to have a regex pattern generator which can easily be incorporated into the Find and Replace feature of visual studio. The reason is because I want to change all instances of html like so: "style='height:26.25pt'" to either empty string "" or in another file to be "style='height:28.25pt'.

If I could just select the text "style='height:26.25pt' by highligiting it first, and then right clicking a context menu that contains generate regex pattern. It would convert it to something like this: "style='height\:\d\.\dpt'" or on the vs2010 like this:"style='height\::z\.:zpt;'". Then I can use the regex to quickly find the pattern. Maybe also include a feature for wildcard generator and a "TEST" button to test the pattern. thx

In the library topic "How to: Synchronize a Producer and a Consumer Thread (C# and Visual Basic)" (http://msdn.microsoft.com/en-us/library/yy12yx1f.aspx), the SyncEvents class keeps an array of its new item and exit thread events and provides this array to consumers to facilitate using those events in a WaitHandle.WaitAny(WaitHandle[]) call.

As implemented, some ConsumerA could assign a value to the array that is not one of the events being used in the current SyncEvents instance. If some ConsumerB then tries to wait on the array, its behavior will be undefined at best (if an unrelated WaitHandle has been assigned) or it will receive an ArgumentNullException at worst. In a debugging scenario, the cause of these problems may very well be non-obvious.

The SyncEvents.EventArray property and its backing field should be removed in favor of a method that returns a new array for each caller. This way, all callers will get references to the correct SyncEvents.NewItemEvent and SyncEvents.ExitThreadEvent in the arrays that they receive, and no one caller can interfere with the wait behavior of the others by modifying its own copy of the array.
