One of the errors I encountered recently when building the MPOS solution is the below error
“10.0.10xxx.0” is not a supported value for TargetPlatformVersion. Please change it on the Project Property page.
I learnt the reason for this after quite some time and with the help of a colleague who faced the same issue, was that , the needed version of Windows SDK was not installed on my machine.
If you get the same error just use the below link to install the right version of the Windows SDK based on the error message.
For instance if it could be 10.0.10586.0.
Hope this helps.
