Having the Mono.Data.Sqlite.Portable NuGet package referenced I can't create builds with Linker behavior "SDK assemblies only", neither for Android nor for iOS.
Error The "LinkAssemblies" task failed unexpectedly. System.NullReferenceException: Object reference not set to an instance of an object. at Mono.Linker.Steps.ResolveFromAssemblyStep.ProcessLibrary(LinkContext context, AssemblyDefinition assembly) at Mono.Tuner.CustomizeActions.ProcessUserAssembly(AssemblyDefinition assembly) at Mono.Tuner.CustomizeActions.ProcessAssembly(AssemblyDefinition assembly) at Mono.Linker.Steps.BaseStep.Process(LinkContext context) at Mono.Linker.Pipeline.Process(LinkContext context) at MonoDroid.Tuner.Linker.Run(Pipeline pipeline, LinkContext context) at MonoDroid.Tuner.Linker.Process(LinkerOptions options, LinkContext& context) at Xamarin.Android.Tasks.LinkAssemblies.Execute(DirectoryAssemblyResolver res) at Xamarin.Android.Tasks.LinkAssemblies.Execute() at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute() at Microsoft.Build.BackEnd.TaskBuilder.<ExecuteInstantiatedTask>d__26.MoveNext() C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets line 1569
* "Link Framework SDK only": Error Could not link assemblies. Reason: Object reference not set to an instance of an object C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets line 747 * "Don't link" produces a huge file and (much worse) makes the AppStore think that any existing app permission is in use, therefore requiring permission request strings for anything. * "Link All" produces a too small file which crashes immediately on launch.
Can't produce a working build for the iOS AppStore right now - any ideas or workarounds are appreciated!
Unfortunately I can't kick the package out, as it is heavily in use...
