Great news for people working on Virtual Machines with BizTalk 2013 on Microsoft Azure.

BizTalk Server 2013 Development Edition is now available as a pre-built image you can select inside the Image Gallery.

I believe this image is only available to uses how have Azure through MSDN.  I tried to access it through another Azure account I had and was not able to see the image. 

I will be testing out the Image over the weekend to see how it looks.
