I'm having a persistent build issue that I can't resolve, I've tried xamarin support forums.

When I build my project, it can't find any of my Xamarin.Android.Support.* packages.

I have all of my Xamarin.Android.Support.* libraries included as nuget packages. They appear correct in my packages.config and csproj file, and the references folder in my project shows they are recognized.

The issue appears to be that the build is looking for these packages in a completely different folder, which is my local user AppData folder. I have no clue why it is looking there, but I think this is the issue.

I'm lost and can't figure out why it is looking here.

  • Have you tried restarting your machine? I'm almost certain I had this happen to me once and I don't think I ever did find a solution or cause. I think restarting my machine fixed it but I'm not 100% sure. – MikeOscarEcho Nov 29 '16 at 18:55

Sometimes Visual Studio will timeout while downloading the appropriate libraries it requires, and it'll give build issues because certain packages appear to be installed, but the files have been corrupted.

What I'd suggest doing is closing Visual Studio, deleting all the files from C:\Users\jwierzba.ASSOCIATIONVOIC\AppData\Local\Xamarin\zips, restarting Visual Studio, and rebuilding the project. This will force Visual Studio to download those libraries again from scratch.

You can fix the 260 character limit by right-clicking on your specific project in Solution Explorer, selecting "Properties", navigating to the "Build" tab, and changing the Output path.

  • I've tried this and it then gave me a "path too long" error. Could you please tell me what is the significance of this app data folder? Why is it placing files in there? Can the location be changed? – James Wierzba Nov 29 '16 at 20:25
  • The app data folder is where VS stores project-related files and builds your project. – Karl Buys Nov 29 '16 at 22:13
  • I believe the Xamarin files stored here exceed the 260 char path limit on Windows. Would you tell me please what exactl setting you are referring to so I can place it closer to the root? – James Wierzba Nov 29 '16 at 22:16
  • Sorry, didn't intend for the last comment to post. Am editting my answer accordingly – Karl Buys Nov 29 '16 at 22:17
  • Karl, if I delete the zip files, it will just re-generate them and try again to unzip them and again exceed 260 chars. Also, the setting you suggested isnt correct. The `Project Properties -> Build -> Output path` is already set to `bin\Debug` which is a folder relative to my visual studio solution folder. This isn't the setting that is pointing to `...\AppData\Local\Xamarin\` , do you know where I can change the drop location of these zip files? – James Wierzba Nov 29 '16 at 22:25
  • Hi James. I'm looking into it a bit more. Will come back to you as soon as I find something that makes sense as a work-around. – Karl Buys Nov 29 '16 at 23:31
  • Thank you Karl I appreciate all the help thus far – James Wierzba Nov 29 '16 at 23:41
