Xamarin-android: [Linking] TypeInitializationException: The type initializer for 'Microsoft.EntityFrameworkCore.Sqlite.Query.ExpressionTranslators.Internal.SqliteCompositeMethodCallTranslator' threw an exception. ---> System.ArgumentNullException: Value cannot be null.

Created on 15 Jan 2019 · 10Comments · Source: xamarin/xamarin-android

This may be related to #1990, however it is not the same issue.

Steps to Reproduce

Create a blank Xamarin Forms application - I called mine "LinkTest". For the test, I created an Android application only.
Add the nuget package "Microsoft.EntityFrameworkCore.Sqlite" v2.2.1
Add the nuget package "System.Buffers" (I am using v4.4.0, but the same problem exists with v4.5.0)
Create a class to represent a table, and a class derived from DbContext exposing that class as a DbSet<T>
Within the DbContext derivative, override OnConfiguring and add the following code before the call to base.OnConfiguring(optionsBuilder);...

            optionsBuilder.UseSqlite($"Filename=/data/user/0/com.companyname/files/LinkText.db", sqliteOptionsBuilder => sqliteOptionsBuilder.SuppressForeignKeyEnforcement());

Within the Application class derivative (in App.xaml.cs), add the following code after the InitializeComponent in the constructor...

            using (LinkTestContext context = new LinkTestContext())
            {
                context.Database.EnsureCreated();
            }

LinkTest_81_Fail.zip

Note: The attached reproduction targets the Android 8.1 SDK, but I have also updated this to SDK 9.0 and have the same results.

Expected Behavior

The application should start, and the default "Welcome to Xamarin.Forms!" should be displayed.

Actual Behavior

When building and running the application in debug, the application behaves as expected.
When building and running the application in release, or building/archiving/distributin(ad-hoc) and installing, an alert pops up "Unfortunately LinkTest.Android has stopped.".
If you then change the "Linking" option within "Properties"/"Android Options" to "None" and run the application in release, the application again behaves as expected.

Looks like the Microsoft.EntityFrameworkCore.Sqlite assembly is not linker friendly.

You can add LinkDescription.xml file containing

<?xml version="1.0" encoding="UTF-8" ?>
<linker>
        <assembly fullname="mscorlib">
                <type fullname="System.DateTime" preserve="methods" />
        </assembly>
</linker>

and set its build action to LinkDescription

Don't know if this helps, but as far as I can see, the code that is failing is a part of Microsoft.EntityFrameworkCore.Sqlite here and seems to be looking for methods of the DateTime class...

        private readonly Dictionary<MethodInfo, string> _methodInfoToUnitSuffix = new Dictionary<MethodInfo, string>
        {
            { typeof(DateTime).GetRuntimeMethod(nameof(DateTime.AddYears), new[] { typeof(int) }), " years" },
            { typeof(DateTime).GetRuntimeMethod(nameof(DateTime.AddMonths), new[] { typeof(int) }), " months" },
            { typeof(DateTime).GetRuntimeMethod(nameof(DateTime.AddDays), new[] { typeof(double) }), " days" },
            { typeof(DateTime).GetRuntimeMethod(nameof(DateTime.AddHours), new[] { typeof(double) }), " hours" },
            { typeof(DateTime).GetRuntimeMethod(nameof(DateTime.AddMinutes), new[] { typeof(double) }), " minutes" },
            { typeof(DateTime).GetRuntimeMethod(nameof(DateTime.AddSeconds), new[] { typeof(double) }), " seconds" }
        };

Could the linker be removing any of these methods because they do not appear to be being used elsewhere? I assume that their usage here would not be detected as after compilation the references will actually be being strings containing the method names rather than references to the methods.

@radekdoulik I assume that this would be within the Android project itself and that I would then return the "Linking" option on the "Android Options" properties tab to the default "SDK Assemblies Only"?

MartinRobins on 22 Jan 2019

Yes, add it to your project, set the build action for it and then hopefully you would be able to enable the linking again.

I tested the solution with Xamarin.iOS. Works fine!

xamadev on 28 Jan 2019

Apologies for the delay in getting back to you. I too have now tested this using the repro that I originally provided for the fault and can confirm that it works for me too.

Thanks for your help.

MartinRobins on 29 Jan 2019

Yup same issue, same fix worked. issue happened to me when upgrading Microsoft.EntityFrameworkCore.Sqlite from 2.1 to 2.2

kkarakk on 30 Jan 2019

I'm getting this same issue on Xamarin.iOS, with the latest version of EFCore 2.2.2. Adding the linker description file as mentioned above worked for me.

We can confirm that this helps also nowadays!

This solved an issue I had with EF Core 3.1.2 on Xamarin IOS as well.
