[.NET 6] Migrate API - Could not find method 'AddYears' on type 'System.DateOnly'

[jianmingyong]

If users were to use the trimming option in .NET 6, one might face this exception if they used Migrate() or MigrateAsync() API.

Could not find method 'AddYears' on type 'System.DateOnly' at System.SharedTypeExtensions.GetRequiredRuntimeMethod(Type type, String name, Type[] parameters)

For now, it can be workaround with adding a line of code (preferably in main class) or using rd.xml

/// <summary>
/// FIXME: This is required for EF Core 6.0 as it is not compatible with trimming.
/// </summary>
[DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.All)]
private static Type _keepDateOnly = typeof(DateOnly);

Include provider and version information

EF Core version: 6.0.0
Database provider: Microsoft.EntityFrameworkCore.Sqlite
Target framework: .NET 6.0
Operating system: Windows 10
IDE: Visual Studio 2022

#26288 tracks making all reflection-based method lookup compatible with trimming (rather than having an issue for each method).

@jianmingyong I've started to look into this, could you please post a full stack trace of the exception you got with AddYears? I'm specifically interested since that exception was triggered from Migrate.
