Adding Fody 2.0.2 to Xamarin.Forms app breaks the build with Microsoft.Build.BuildEngine.InvalidProjectFileException

See original GitHub issue

I created a clean Multi Platform Xamarin.Forms app. Built in debug mode and it worked fine. Added Fody 2.0.2 and built again and it errors with the following:

Error: Error building target AfterCompile: Microsoft.Build.BuildEngine.InvalidProjectFileException: Unable to parse condition "Exists(@(IntermediateAssembly))" : Expected an item list at position 8 in condition "Exists(@(IntermediateAssembly))". Missing opening parantheses after the '@'. ---> Microsoft.Build.BuildEngine.ExpressionParseException: Expected an item list at position 8 in condition "Exists(@(IntermediateAssembly))".

I’m using Xamarion Studio 6.3 (build 863) which is using Mono 5.0.0.61 on macOS Sierra 10.12.4.

The Xamarin.Forms PCL project .NET Portable Profile is: Profile111

I tried changing it to Profile259 and I still get the same error.

I tried changing Xamarin Studio to use Mono 4.8.1 and I still get the same error.

Let me know if you need anything else from me.

Thanks,

John

i suspect u have been bitten by the nuget bug that it always resolved the lowest dependencies. try explicitly adding a ref to the newest version of fody
