Microsoft has just published some early specifications ( about the new Visual Studio “Orcas” and among them, it is the “CommandBar Improvements” ( which has an intriguing paragraph: “The work we will do here will cause us to diverge from Office’s MSO Commmand Bar look and feel.

Visual Studio, add-ins and Windows Vista

November 24, 2006

Microsoft has a FAQ: Visual Studio and Windows Vista ( where it is stated that Visual Studio .NET 2002/2003 will not be supported on Windows Vista, and that only VS 2005 will be supported with the SP1 and a (post-SP1) Vista Support Update. I have some comments about this: The first one is that although .NET Framework 1.x […]

The Add-In Manager of Visual Studio 2005 got broken…and won’t be fixed for SP1

Well, sometimes you will find that your add-in does not appear in the Add-In Manager at all, or it doesn’t load (apparently) or it causes some COM exception when it is […]

It’s about time!

November 8, 2006

Finally I decided to start a blog about Visual Studio extensibility: macros, add-ins, templates, SDK packages, and so on. My name is Carlos Quintero, I am from Madrid (Spain) (so I do not speak English natively as you will notice) and I am Microsoft Most Valuable Professional (MVP) since 2004. If you have come to […]
