An update to my last plea for help.
I was able to install .NET Micro Framework SDK 4.3 (QFE2) and Netduino SDK v4.3.1 (Nov 2014) on my Windows 8.1 system with VS Express 2012. When I started VS and selected 'New Project', the Micro Framework template appeared under both Visual Basic and Visual C#. Within the Micro Framework template I was able to choose from several Netduino applications templates. I selected 'Netduino Plus 1 Application'.
When I did that, an error message popped up:
The project file
'<long file path>NetduinoApplication6.csproj' cannot be opened.
There is a missing project subtype.
Subtype: '{b69e32 ......a37f}' is unsupported by this installation.
I got a similar error pop-up no matter which Netduino template I chose, under both Visual Basic and Visual C#.
Can someone explain what's happening here?
Thanks,
Paul
