Entity Framework Core 7 نسخه نهایی

Entity Framework Core (EF Core) 7 is available on NuGet today!

EF Core 7 is the successor to EF Core 6, and can be referred to as EF7 for brevity. EF Core 7 contains many features that help in porting “classic” EF6 applications to use EF7. As such, we encourage people to upgrade existing classic EF applications to use EF7 where possible. See Porting from EF6 to EF Core for more information.

GitHub Issues

The GitHub Issues integration allows you to search and reference your issues from the commit message box in VS, in response to this suggestion ticket. You can reference an issue or a pull request by typing # or clicking on the # button in the lower right side of the commit message text box. If you weren't already authenticated to access related issues, you will now be prompted to sign in to take advantage of this feature.

Line Unstaging

To continue improving our line-staging (aka interactive staging) feature, we've added unstage. You can now use the tool tip option to unstage changes, line by line, as requested here Unstage individual lines and hunks in a file - 4 votes

Arm64

We continue to build native support for Arm64 on Windows 11 for the most popular developer scenarios. We now support the .NET Multi-platform App UI (MAUI) workload on Arm64 Visual Studio.

C++

  • Available as a preview feature, you can now view Unreal Engine logs without leaving VS. To see the logs from the Unreal Engine Editor, click View > Other Windows > UE Log. To filter your logs, click on the "Categories" or "Verbosity" dropdowns. Since this is an experimental feature, feedback is greatly appreciated.
  • You can now import STM32CubeIDE projects for embedded development within Visual Studio with File > Open > Import STM32CubeIDE project. This generates a CMake project with device flashing and debugging settings for STLink. You must have the STM32CubeIDE installed with the board support package for your device. More details available here.
  • You can use the new CMake Debugger to debug your CMake scripts at build time. You can set breakpoints based on filenames, line numbers, and when CMake errors are triggered. Additionally, you can view call stacks of filenames and watch defined variables. Currently, this only works with bundled CMake, and projects targeting WSL or remote machines are not supported yet. We are actively working to add more support to the CMake debugger, and feedback is greatly appreciated.

شروع به کار با EF Core 1.0 - قسمت 6 - تعیین نوع‌های داده و ویژگی‌های آن‌ها
یک نکته‌ی تکمیلی: چگونه دقت خواصی از نوع decimal را به صورت سراسری تنظیم کنیم؟

فرض کنید قصد دارید دقت خواصی از نوع decimal را تنظیم کنید تا با اخطار زیر مواجه نشوید:
No type was specified for the decimal column 'Price' on entity type 'Movie'. 
This will cause values to be silently truncated if they do not fit in the default precision and scale.
یک روش رفع آن، قرار دادن ویژگی Column بر روی تک تک خواص از نوع decimal، در تمام موجودیت‌های تعریف شده و تنظیم دقت آن‌ها است:
public class Movie
{
    public int ID { get; set; }

    [Column(TypeName = "decimal(18, 2)")]
    public decimal Price { get; set; }
}
روش دیگر، انجام این تنظیم به صورت سراسری است:
protected override void OnModelCreating(ModelBuilder builder)
{
    base.OnModelCreating(builder);

    foreach (var property in builder.Model.GetEntityTypes()
                                    .SelectMany(t => t.GetProperties())
                                    .Where(p => p.ClrType == typeof(decimal)
                                                || p.ClrType == typeof(decimal?)))
    {
       property.SetColumnType("decimal(18, 6)");
    }
}
که هر دو نوع خاصیت decimal و ?decimal را پوشش می‌دهد.

معرفی NET 5 Preview 4.

.NET apps can now run natively on Windows ARM64. This follows the support we added for Linux ARM64 in .NET Core 3.0. With .NET 5.0, you can develop web and UI apps on Windows ARM64 devices, and deliver your applications to users who own Surface Pro X and similar devices. You can already run .NET Core and .NET Framework apps on Windows ARM64, but via x86 emulation. It’s workable, but native ARM64 execution has much better performance.
