Microsoft has released NETMF 4.1. More details come very soon but I thought I will let you know that you can now use Visual Studio 2010 and NETMF 4.1 with FEZ.
The FEZ firmware is still 4.0 firmware but what is nice about NETMF 4.1 SDK is that you can use 4.0 or 4.1 devices.
Finally, the 4.1 firmware for FEZ is coming very in few days to the beta pages. So for now, upgrade your visual studio to VS2010 express or professional and install NETMF 4.1 SDK
I was using VS2008 with .NET Micro 4.0, and everything was working fine.
So after seeing this post I installed .NET Micro 4.1 and ran the default ‘Hello world’ using VS2010, and I got this:
Error 1 Cannot deploy the base assembly ‘mscorlib’, or any of his satellite assemblies, to device - USB:USBizi twice. Assembly ‘mscorlib’ on the device has version 4.0.1681.0, while the program is trying to deploy version 4.1.2821.0
I just installed VS2010 (Pro) and .NETMF 4.1. Everything went without a hitch but I did leave VS2005 installed and removed .NETMF 4.0 before starting. I really, really, really like VS2010. The changed to a WPF based UI was a great choice. Everything looks soooo much better.
