I have a web solution which is built and deployed using TeamCity on windows.
We've recently started building a Xamarin mobile app for this web solution and we are sharing some entities between the web app and the mobile app using a PCL - Portable Class Library.
Since we've created the PCL, the build server can no longer build and deploy the web solution.
It builds quite happily in Visual Studio 2015 on a developer PC.
We use MSBUILD.
The error we get in the build is this:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\AppxPackage\Microsoft.AppXPackage.Targets(975, 5): error APPX3212: SDK root folder for 'Portable 7.0' cannot be located. See http://go.microsoft.com/fwlink/?prd=12560&pver=1.0&plcid=0x409&ar=MSDN&sar=PlatformMultiTargeting&o1=Portable&o2=7.0 for more information.
How can I fix this?
Do I need to add something to the Build Server?
