构建xamarin.forms Android解决方案会导致Monoandroid10的BadImageFormatException

Question

Been developing an application which, as for now, runs only on iOS and everything runs great here. Now I want to run the Android Project, but I keep getting this error:

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets(2,2): Error: Exception while loading assemblies: Java.Interop.Tools.Diagnostics.XamarinAndroidException: error XA0009: Error while loading assembly: /Users/ulriksandberg/.nuget/packages/system.runtime.loader/4.3.0/lib/MonoAndroid10/ . ---> System.BadImageFormatException: Format of the executable (.exe) or library (.dll) is invalid.

I'm running on the local emulator Android_Accelerated_Oreo, or atleast I want to.

Answer 1

XA0009 Error while loading assemblies: {0}.

Much of the reason for this error is due to the fact that the program is loading NuGet packages or other bound library files.You can try the following method：

1. Check if there are any unused Nuget packages in the project, but keep a reference to them, then you need to remove all references related to them.
2. Check if there are incorrectly installed Nuget packages, please reinstall them
3. If there is a library file reference, the same processing as the Nuget package
