How To Continuously Deploy Your .NET Core Azure WebJobs

WebJobs is a feature of Azure App Service that enables you to run a program or script in the same instance as a web app, API app, or mobile app. Since this runs as part of the same instance as the Web App, there is no additional cost to use WebJobs. WebJobs is not supported on a Linux App Service.

The Azure WebJobs SDK simplifies the task of writing WebJobs. Version 3.x of WebJobs SDK supports both .NET Core and .NET Framework. At the time of writing, there are no code templates to create an Azure WebJob .NET Core application in Visual Studio. However, setting up is not that hard and well explained in the Getting started with Azure WebJobs SDK article.

Set Up Azure WebJob

All you need to do is create a .NET Core Console application (from the Visual Studio templates), add the Microsoft.Azure.WebJobs and Microsoft.Azure.WebJobs.Extensions NuGet packages. Update the Program.cs file in the .NET Console Application to use the HostBuilder as shown. If you want to log to the console, also add the Microsoft.Extensions.Logging.Console NuGet package.

To run the host in development mode  call the UseEnvironment  method on the builder and set it to development . It increases the queue polling interval, sets log level to verbose, etc., and makes development more efficient.

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_._

Once you provide the project name and location. Select Web Application(Model-View-Controller) and uncheck HTTPS Configuration. Above steps will create a brand new ASP.NET Core MVC project.

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.

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.

MVC User Registration & Login with ASP.NET Core Identity

User registration and authentication are mandatory in any application when you have little concern about privacy. Hence all most all application development starts with an authentication module. In this article, we will discuss the quickest way to use **ASP.NET Core Identity for User Login and Registration **in a new or existing MVC application.

Sub-topics discussed :

• How to add ASP.NET Core Identity to MVC application.
• Customize ASP.NET Core Identity.
• Identity.UI Design Customization.
• Next step.

Background

ASP.NET Core Identity is an API, which provides both user interface(UI) and functions for user authentication, registration, authorization, etc. Modules/ APIs like this will really be helpful and fasten the development process. It comes with ASP.NET Core Framework and used in many applications before. Which makes the API more dependable and trustworthy.

ASP.NET Core MVC with user authentication can easily be accomplished using Identity.UI. While creating the MVC project, you just need to select Authentication as Individual User Accounts.

The rest will be handled by ASP.NET Core Identity UI. It already contains razor view pages and backend codes for an authentication system. But that’s not what we want in most of the cases. we want to customize ASP.NET Core Identity as per our requirement. That’s what we do here.

Create an ASP.NET Core MVC Project

First of all, I will create a brand new ASP.NET Core MVC application without any authentication selected. We could add ASP.NET Core Identity later into the project.

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N). From new project window, select ASP.NET Core Web Application.

Once you provide the project name and location. A new window will be opened as follows, Select _Web Application(Model-View-Controller), _uncheck _HTTPS Configuration _and DO NOT select any authentication method. Above steps will create a brand new ASP.NET Core MVC project.

Using Azure AD groups authorization in ASP.NET Core for an Azure Blob Storage

This post show how Azure AD groups could be used to implement authorization for an Azure Blob storage and used in an ASP.NET Core Razor page application to authorize the identities. The groups are assigned the roles in the Azure Storage. Azure AD users are added to the Azure AD groups and inherit the group roles. The group ID is added to the claims of the tokens which can be used for authorization in the client application.

Implement a full text search using Azure Cognitive Search in ASP.NET Core

This article shows how to implement a full text search in ASP.NET Core using Azure Cognitive Search. The search results are returned using paging and the search index can be created, deleted from an ASP.NET Core Razor Page UI.

Code: https://github.com/damienbod/AspNetCoreAzureSearch

Creating the Search in the Azure Portal

In the Azure Portal, search for Azure Cognitive Search and create a new search service. Create the search using the portal wizard and choose the correct pricing model as required. The free version supports three indexes but does not support managed identities. This is good for exploring, evaluating the service.

If using the free version, you will need to use API keys to access the search service. This can be found in the **Keys **blade of the created cognitive search.

Of course the Azure Cognitive Search could also be created using Azure CLI, Arm templates or Powershell. The service can also be created direct from code.

Create an Azure Cognitive Search index

In the ASP.NET Core Razor page application, the Azure.Search.Documents nuget package is used to create and search the Azure Cognitive search service. Add this to your project.

The index and the document field definitions can be created in different ways. We will use attributes and add these to the document search class properties to define the fields of the documents.

Azure Active Directory's gateway is on .NET Core 3.1!

Azure Active Directory’s gateway service is a reverse proxy that fronts hundreds of services that make up Azure Active Directory (Azure AD). If you’ve used services such as office.com, outlook.com, azure.com or xbox.live.com, then you’ve used Azure AD’s gateway. The gateway provides features such as TLS termination, automatic failovers/retries, geo-proximity routing, throttling, and tarpitting to services in Azure AD. The gateway is present in more than 53 Azure datacenters worldwide and serves ~115 Billion requests each day. Up until recently, Azure AD’s gateway was running on .NET Framework 4.6.2. As of September 2020, it’s running on .NET Core 3.1.

Motivation for porting to .NET Core

The gateway’s scale of execution results in significant consumption of compute resources, which in turn costs money. Finding ways to reduce the cost of executing the service has been a key goal for the team behind it. The buzz around .NET Core’s focus on performance caught our attention, especially since TechEmpower listed ASP.NET Core as one of the fastest web frameworks on the planet. We ran our own benchmarks on gateway prototypes on .NET Core and the results made the decision very easy: we must port our service to .NET Core.
