I want to know the answer to the following question:
What developer tools did the build have?
All the background I'm provided with is that "The build was released for download later in the day in standard 32-bit and 64-bit versions, plus a special 64-bit version which included SDKs and developer tools (Visual Studio Express and Expression Blend) for developing Metro-style apps.". Is that enough to answer the question?
Answer: yes
