Darren Gosbell announced on his blog that DAX Studio 2.0 is available. This new release has a completely new user interface, a renewed architecture, and also works as a standalone executable without Excel. Yes, you read it right. You can use DAX Studio on a server without having to run it in Excel. You can now connect with Remote Desktop to your SSAS Tabular server and create DAX queries with a decent editor.
I don’t see any good reason to use SSMS to run DAX queries now. Until yesterday, the zoom in the editor was the only one, but now also this feature is available in DAX Studio. I could spend other lines of this blog post describing the other new features, but I don’t see how this could be more important than doing the only thing you should do at this point: download, install and use it!
