Tonight I start looking how the new emulator is integrated in Visual Studio 2010. Using Process Explorer I saw that VS launches this command:
"C:\Program Files\Microsoft XDE\1.0\XDE.exe" "C:\Program Files\Microsoft SDKs\WindowsPhone\v7.0\Emulation\Images\WM70C1.bin"
So the new Device Emulator changed name in XDE (version 10.0.30128.39) and we have the bin file that contains the emulator image. I then remembered that you can extract the files from a bin image, but the guys at XDA were already ahead. They made a dump of the ROM files. A lot of people are digging up and we might see some interested things in the next couple of days.
This is what I've found out. The new OS, build 18.104.22.16877, has NET CF 3.7 embedded. I then remembered that there was a CF 3.7 cab version that was running on WM 6.5 and I got this "crazy" idea that I have to try... What if we could run the Silverlight applications that we compile for WP 7 on WM 6.5? I'm gonna dig this up tomorrow.
Anyway in the dump files I could find the Silverlight assemblies:
that might just work on WM 6.5
and also the XNA assemblies:
XnaFrameworkCore.dll it's a native file so I think we would need one from a real device not emulator.
There is also SQL Ce Compact 3.5
GAC_System.Data.SqlServerCe_v3_5_1_0_cneutral_1.dll the version is 3.5.5722.1
And more managed assemblies:
It's a start...We can look a little under the hood of WP 7 and see how it is designed. Pretty interesting, right?
