یک نکته‌ی تکمیلی: تبدیلگرهای DateTimeOffset برای بانک‌های اطلاعاتی که از آن پشتیبانی نمی‌کنند
خود EF Core به همراه تبدیلگرهای توکار زیر برای کار ساده‌تر با DateTimeOffset در بانک اطلاعاتی‌هایی مانند SQLite و یا MySQL است:
DateTimeOffsetToBinaryConverter - DateTimeOffset to binary-encoded 64-bit value (stores it as a long, slight reduction in precision)
DateTimeOffsetToBytesConverter - DateTimeOffset to byte array (stores it as a 12 byte array, 8 bytes for time, 4 bytes for offset. Full precision.)
DateTimeOffsetToStringConverter - DateTimeOffset to string (ISO 8601 string including timezone)
و برای مثال می‌توان آن‌ها را به صورت زیر و سراسری، به سیستم معرفی کرد:
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
if (Database.ProviderName == "Microsoft.EntityFrameworkCore.Sqlite")
{
// SQLite does not have proper support for DateTimeOffset via Entity Framework Core, see the limitations
// here: https://docs.microsoft.com/en-us/ef/core/providers/sqlite/limitations#query-limitations
// To work around this, when the Sqlite database provider is used, all model properties of type DateTimeOffset
// use the DateTimeOffsetToBinaryConverter
// Based on: https://github.com/aspnet/EntityFrameworkCore/issues/10784#issuecomment-415769754
// This only supports millisecond precision, but should be sufficient for most use cases.
foreach (var entityType in builder.Model.GetEntityTypes())
{
var properties = entityType.ClrType.GetProperties().Where(p => p.PropertyType == typeof(DateTimeOffset));
foreach (var property in properties)
{
builder
.Entity(entityType.Name)
.Property(property.Name)
.HasConversion(new DateTimeOffsetToBinaryConverter());
}
}
}
} 
سلام. من می‌خواستم توی پروژه ام که از identity استفاده کردم این مبحث رو بگنجانم که بتونم هم از identity استفاده کنم و هم از jwt. چگونه می‌تونم از هردو با هم استفاده کنم و وقتی با jwt لاگین شد توی identity هم لاگین بشه و بالعکس.
Input Validation for me is about validating the user input. Some people call "Name must not be empty" a business rule, I think about it as input validation. Business Rules validation is more complex, because a business rule for me is not "Name must not be empty", it is a definition of a state in the system that requires an action. Here is a definition of a business rule:
An order should be payed within 30 days, this duration can be extended, to a maximum of three times.

HTTP/2 PUSH is a feature that lets a server pre-emptively push resources to the client (without a corresponding request). HTTP Preload is a way to indicate to the browser resources it would require while loading the current page. In this post, we will discuss the key differences between PUSH and Preload, with a detailed explanation of which one to choose based on your use case.
