    public static WinApplication BuildApplication(string connectionString) {
        var builder = WinApplication.CreateBuilder();
        builder.UseApplication<MySolutionWindowsFormsApplication>();
        builder.ObjectSpaceProviders
            .AddSecuredEFCore(options => options.PreFetchReferenceProperties())
            .WithDbContext<MySolutionEFCoreDbContext>((application, options) => {
                // ...
            })
