Xamarin“GenerateResourceDesigner”任务意外失败，找不到.dll文件

Question

Hi I'm running a Xamarin PCL project thats deploying to all platforms including UWP windows 10 and windows 8.

I've just merged a branch on git and resolved some conflicts (not very well clearly) and i'm getting a few errors.

The first error:

The "GenerateResourceDesigner" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load assembly 'Vigour, Version=, Culture=neutral, PublicKeyToken='. Perhaps it doesn't exist in the Mono for Android profile?
File name: 'Vigour.dll'

   at Xamarin.Android.Tuner.DirectoryAssemblyResolver.Resolve(String fullName, ReaderParameters parameters)

   at Microsoft.Build.BackEnd.TaskBuilder.<ExecuteInstantiatedTask>d__26.MoveNext() Vigour.Droid            

The second one:

I know this is a common problem and I've tried to un-tick and tick the build of each project in the solutions configuration.

I've also tried to remove the .vs/../.suo file to reset the project

However I've had no luck. I think that it might have something to do with the merger that involved changing the .csproj files.

Answer 1

尝试将API设置为23然后重建项目它将解决问题

Answer 2

解决这个问题的方法是重新安装android的xamarin表单，并且@ hvaughan3说，删除所有目录的bin和obj文件夹以及包。

Answer 3

In my case, I was getting error The "ResolveLibraryProjectImports" task failed unexpectedly. when I open a project downloaded from Xamarin.University on Windows 10 and the path for one of the files ends up being to long (longer than 260 characters). So, to solve my problem, I would copy the directory as shallow as possible, so instead working directly in the structure of downloaded project, I would copy deepest directory containing the project into my C:. Building would work then without an issue as the path to all files in the project got shortened.

So, say my downloaded structure from Xamarin.University is something like C:\\Users\\me\\Desktop\\XAMARIN\\XAMARIN CERTIFICATION\\forms\\xam300-advanced-cross-platform-development\\Lab Materials\\Part 03 Resources\\Completed

I would copy the Completed folder into C and end up with much shorter path like: C:\\Completed
