Announcing .NET 6 Preview 5

We are thrilled to release .NET 6 Preview 5. We’re now in the second-half of the .NET 6 release, and starting to see significant features coming together. A great example is .NET SDK Workloads, which is the foundation of our .NET unification vision and enables supporting more application types. Like other features, it is coming together to provide a compelling end-to-end user experience.

You can download .NET 6 Preview 5 for Linux, macOS, and Windows.

See the ASP.NET CoreEF Core, and .NET MAUI posts for more detail on what’s new for web, data access, and cross-platform UI scenarios.

Visual Studio 2022 Preview 1 is also releasing today and .NET 6 Preview 5 is included in that release. .NET 6 has also been tested with Visual Studio 16.11 and Visual Studio for Mac 8.9. We recommend you use those builds if you want to try .NET 6 with Visual Studio.

Check out the new conversations posts for in-depth engineer-to-engineer discussions of the latest .NET features.

jQuery Ajax CRUD in ASP.NET Core MVC with Modal Popup

In this article, we’ll discuss how to use jQuery Ajax for ASP.NET Core MVC CRUD Operations using Bootstrap Modal. With jQuery Ajax, we can make HTTP request to controller action methods without reloading the entire page, like a single page application.

To demonstrate CRUD operations – insert, update, delete and retrieve, the project will be dealing with details of a normal bank transaction. GitHub repository for this demo project : https://bit.ly/33KTJAu.

Sub-topics discussed :

  • Form design for insert and update operation.
  • Display forms in modal popup dialog.
  • Form post using jQuery Ajax.
  • Implement MVC CRUD operations with jQuery Ajax.
  • Loading spinner in .NET Core MVC.
  • Prevent direct access to MVC action method.

Create ASP.NET Core MVC Project

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N).

From new project window, Select Asp.Net Core Web Application_._

Setup a Database

Let’s create a database for this application using Entity Framework Core. For that we’ve to install corresponding NuGet Packages. Right click on project from solution explorer, select Manage NuGet Packages_,_ From browse tab, install following 3 packages.

Showing list of NuGet Packages for Entity Framework Core

Now let’s define DB model class file – /Models/TransactionModel.cs.

public class TransactionModel
{
    [Key]
    public int TransactionId { get; set; }

    [Column(TypeName ="nvarchar(12)")]
    [DisplayName("Account Number")]
    [Required(ErrorMessage ="This Field is required.")]
    [MaxLength(12,ErrorMessage ="Maximum 12 characters only")]
    public string AccountNumber { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Beneficiary Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BeneficiaryName { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Bank Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BankName { get; set; }

    [Column(TypeName ="nvarchar(11)")]
    [DisplayName("SWIFT Code")]
    [Required(ErrorMessage = "This Field is required.")]
    [MaxLength(11)]
    public string SWIFTCode { get; set; }

    [DisplayName("Amount")]
    [Required(ErrorMessage = "This Field is required.")]
    public int Amount { get; set; }

    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime Date { get; set; }
}

C#Copy

Here we’ve defined model properties for the transaction with proper validation. Now let’s define  DbContextclass for EF Core.

Announcing .NET 6 Preview 1

Today, we are happy to deliver the first preview of .NET 6 and share what you can expect from the new release. We have been defining the overall shape of the release for the last few months, including a large set of new experiences and capabilities. The heart of .NET 6 is delivering the final parts of the .NET unification plan that started with .NET 5. The release will also include major improvements across all parts of .NET, including for cloud, desktop, and mobile apps. It will take multiple previews for the larger scope of the release to be fully available in .NET 6 builds.

You can download .NET 6 Preview 1, for Windows, macOS, and Linux.

See the ASP.NET Core and EF Core posts for more detail on what’s new for web and data access scenarios.

.NET 6 has been tested with Visual Studio 16.9 Preview 4 and Visual Studio for Mac 8.9. We recommend you use those builds if you want to try .NET 6.

The rest of the both is split into two sections: a first look at what we’re delivering for .NET 6 generally (what you’ll get in November), and what’s new in Preview in particular.

Announcing Entity Framework Core (EF Core) 5 RC2

Today, the Entity Framework Core team announces the second release candidate (RC2) of EF Core 5.0. This is a feature complete release candidate of EF Core 5.0 and ships with a “go live” license. You are supported using it in production. This is a great opportunity to start using EF Core 5.0 early while there is still time to fix remaining issues. We’re looking for reports of any remaining critical bugs that should be fixed before the final release.

Prerequisites

EF Core 5.0 will not run on .NET Standard 2.0 platforms, including .NET Framework.

How to get EF Core 5.0 Release Candidate 2

EF Core is distributed exclusively as a set of NuGet packages. For example, to add the SQL Server provider to your project, you can use the following command using the dotnet tool:

dotnet add package Microsoft.EntityFrameworkCore.SqlServer --version 5.0.0-rc.2.20475.6
