如何在ASP.NET上运行EFCore迁移重试启动？

services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

using (var scope = app.ApplicationServices.GetRequiredService<IServiceScopeFactory>().CreateScope())
{
    var dbContext = scope.ServiceProvider.GetService<ApplicationDbContext>();
    dbContext.Database.Migrate();
}

services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))
        .EnableRetryOnFailure(maxRetryCount: 5, maxRetryDelay: TimeSpan.FromSeconds(30), errorNumbersToAdd: null));

var retryPolicy = Policy.Handle<SqlException>()
    .WaitAndRetry(new[]
    {
        TimeSpan.FromSeconds(1),
        TimeSpan.FromSeconds(2),
        TimeSpan.FromSeconds(3)
    });

retryPolicy.Execute(() =>
{
    using (var scope = app.ApplicationServices.GetRequiredService<IServiceScopeFactory>().CreateScope())
    {
        var dbContext = scope.ServiceProvider.GetService<ApplicationDbContext>();
        dbContext.Database.Migrate();
    }
});
