With the general public release of Visual Studio 2010 Beta 2 today, this latest version has created a lot of hype and interest.

Indeed, the opinion I've gauged is that VS 2010 has resolved a great deal of the minor flaws left over from previous versions, as well as added some particularly useful new code editor and project development tools (in particular the Premium/Ultimate versions).

My question here is: what are you favourite new features in VS 2010 that have really got you excited? Or similarly, what are the flaws of VS 2008 that you are most glad to have resolved?

There is a wealth of changes in VS 2010, of course, but these are some of the ones that have interested me most (about which I know!).

• Integrated support for F# (with multi-targeting for .NET 2.0 - 4.0)/
• Much improved WPF designer. The VS 2008 was more than a bit buggy at times.
• Great improvements to the code editor, such as call hierarchy viewing.
• A decent add-in framework.
• A greatly expanded testing framework (now capable of database testing, for example) in Premium/Ultimate.
• Project planning and modelling features in Premium/Ultimate.

If I could request one point/feature per post, I think that would be best, so we could vote them individually.
