JoséJunior · April 2019

Hi I have an app on the test channel of the play store, it was work fine, but I solved use Entity Framework, when I released a version the app stoped to work, on Visual Studio run normally but if I install using apk file and try open it not work.
When I install app using abd shell and I get the follow stacktrace:

It's looks like for me who a project lost references to Entity Framework, when app start it try run migration, follow my code:

public partial class App : PrismApplication
    {

    // omitted default constructors

        protected override async void OnInitialized()
        {
            InitializeComponent();
            //TODO: depois que lançar versão oficial do app remover essa rotina de exclusão de banco de dados
            using (IAppDbContext db = new AppDbContext(new DbContextOptionsBuilder<IAppDbContext>().UseSqlite(new SqliteConnection(Container.Resolve<IDBUtils>().ObterCaminhoBanco())).Options))
            {
                using (DbConnection conn = db.Database.GetDbConnection())
                {
                    if (conn.State.Equals(ConnectionState.Closed))
                    {
                        conn.Open();
                    }
                    using (var command = conn.CreateCommand())
                    {
                        command.CommandText = @"Select Count(name) from sqlite_master where type = 'table' and  name = 'Sessoes';";
                        bool baseNaoMigrada = !Convert.ToBoolean(command.ExecuteScalar());
                        if (baseNaoMigrada)
                        {
                            db.Database.EnsureDeleted();
                        }
                    }
                }
            }

            using (IAppDbContext db = new AppDbContext(new DbContextOptionsBuilder<IAppDbContext>().UseSqlite(new SqliteConnection(Container.Resolve<IDBUtils>().ObterCaminhoBanco())).Options))
            {
                db.Database.Migrate();
            }
            string pagina = SessaoUsuario.UsuarioEstaLogado ? string.Format("/" + ViewsNamesConstants.PREFIXO_VIEW_MASTER_DETAIL, ViewsNamesConstants.MASTER_DETAIL, ViewsNamesConstants.MAPA) : string.Format(ViewsNamesConstants.PREFIXO_VIEW, ViewsNamesConstants.LOGIN);
            await NavigationService.NavigateAsync(pagina);
        }

         // omitted OnResume, OnSleep and RegisterTypes
    }

Have some configuration I need to do in Release? I didn't understand because in Debug my app work fine

TakeShika · January 2020

Had the same following errors:
// android.runtime.JavaProxyThrowable: System.ArgumentException: The method 'b[Microsoft.EntityFrameworkCore.Migrations.Operations.Builders.OperationBuilder1[Microsoft.EntityFrameworkCore.Migrations.Operations.AddColumnOperation],Microsoft.EntityFrameworkCore.Migrations.Operations.Builders.OperationBuilder1[Microsoft.EntityFrameworkCore.Migrations.Operations.AddColumnOperation]].c' is not a property accessor
// Parameter name: propertyAccessor .......

In my case, the combination of dotfuscator and ef was doing all the trouble.

How solved:
1. Make a new .net standard library project in the solution.
2. Reference that project, and move ALL code files related to ef to the new project.
3. Open dotfuscator GUI (from "Tools") and exclude the entire dll file for the new project from renaming.
Open your DotfuscatorConfig -> Renaming -> Exclusions -> check the new project dll

If you can't find the dll on step 3, try the following

Editing your csproj. Find this line...
false

and change it to true
true

Rename your DotfuscatorConfig file something like DotfuscatorConfig_bkup
Compile your app and let VS rebuild the config file. The compile itself will most likely fail.
Revert step 1 (change back to false)
