Error The "ResolveLibraryProjectImports" task failed unexpectedly

I'm getting and error when trying to compile an Android project in VS2017 with Xamarin. I was getting a string type not allowed error and one of the suggestions was to update all my Xamarin.Android references. I found one that dealt with observables for the Xamarin.Core so I installed it. Every since then I have been getting the resolution error. I have tried deleting the obj and bin directories and restart vs and my laptop.

Here is the text for the error

Error       The "ResolveLibraryProjectImports" task failed unexpectedly.

I was getting this when I added a reference to Xamarin.GooglePlayServices.Ads to my project via NuGet. As soon as I did this I got the same issue as the OP. Moving my code to the root directory of my C drive didn't help either, unfortunately; however, per Alper Ebicoglu's suggestion, I added...

<UseShortFileNames>True</UseShortFileNames>

... To my project file in the property group for my build configs. After I reloaded the project in Visual Studio, I was able to get my project to build.

Hope this helps!

Had same problem. This is how I fixed it

  1. Restart Visual Studio
  2. Open the Project
  3. Clean the solution
  4. Rebuild the solution
  5. Close solution
  6. Reopen the project

Here is the problem: System.IO.PathTooLongException: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

Try to move you project to another location like "C:/" , or change the name of the project for something more brief

I've just answered this on another SO question (https://stackoverflow.com/a/44780549/31580).

The crux of it is that if your solution is saved to a location with a long path then this can cause some files to have a path which exceeds the maximum for Windows (260 characters)

Try moving the solution to the root of your C or D (if you have one).
