Instead of buying VS 2010 what options will you use for .net development in the future?

Given the recent release of VS 2010 I was shocked to see the pricing structure for the different versions of the product. I was lucky enough to receive free versions of VS 2005 and 2008 from attending various MS events. For the hacking I do at home I'm not sure I'm going to spend the money to purchase the IDE and wanted to see what other...

How is IObservable<double>.Average supposed to work?

Update Looks like Jon Skeet was right (big surprise!) and the issue was with my assumption about the Average extension providing a continuous average (it doesn't).

Hi all, I've got a Jquery UI dialog that pops up to confirm the creation of an item after filling out a form.

I checked the version and i have .NET 2 sp1, 3 sp1, 3.5, and two variants of 4.0 (client and extended beta). I looked in prerequisites and the...

Are finalizers ever allowed to call other managed classes' methods?

I used to be pretty sure the answer is "no", as explained in Overriding the Finalize method and Object.Finalize documentation. However, while randomly browsing through FileStream in Reflector, I found that it can actually call just such a method from a finalizer: private SafeFileHandle _handle; ~FileStream() { if (this._handle != ...

How do I make a form transparent while keeping the controls fully visible?

I would like to have a form in which the controls on the form are fully visible but the form itself is invisible. If I change the form's Opacity, this makes both the form and the controls on it semi-transparent, so this doesn't work. I can't do this by setting the form's TransparencyKey, since I have a PictureBox on the form. If the i...
