I am unable to build the iOS samples AudioGenerator and AudioConverterFileConverter using Visual Studio 2013 Update 3. For some reason the reference to monotouch cannot be resolved, and the project fails to build with the following error:
C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets(1697,5): warning MSB3245: Could not resolve this reference. Could not locate the assembly "monotouch". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.
Here is the complete build log: https://gist.github.com/ChrisBlackman/2352a42e8411c67fabf5
The .csproj files of the projects seem to be set up correctly, referencing monotouch using '<Reference Include="monotouch" />' which I believe is the right way to do it. Other projects referencing monotouch in this way are working.
I am using Xamarin VS 3.0.143 in Visual Studio 2013 Update 3 on Windows 8.1, with Xamarin.iOS 18.104.22.168.
The samples AudioGenerator and AudioConverterFileConverter are in the monotouch-samples repository, but I've included them in this Dropbox folder for convenience: https://www.dropbox.com/sh/1v779bcnwi9fxdc/AAB7kpSJicRfqMkl_IEBpcQja?dl=0
A fix I found for this was to remove this line from the .csproj file
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
but keep this one in there.
<Import Project="$(MSBuildExtensionsPath)\Xamarin\iOS\Xamarin.MonoTouch.CSharp.targets" />
This only happens to me with projects created on OSX which I then later checkout a git/svn repo and build on Windows. No idea what *.CSharp.targets actually are either.
Today, I have checked this issue with:
Now this issue is not exists, we are successfully able to run build the iOS samples AudioGenerator and AudioConverterFileConverter through VS.
Hence closing this issue.
