provided in this post, you need to have Visual Studio 2022 installed in your system. If you don’t already have a copy, you can download Visual Studio 2022

here. Likewise note that you will need to register for a SendGrid account to use the service. The totally free strategy enables you to send out 100 e-mails per day.Create an ASP.NET Core 7 Web API project in Visual Studio 2022 First off,

let’s develop an ASP.NET Core 7 minimal Web API task in Visual Studio 2022. Follow these steps: Release the Visual Studio 2022 IDE. Click “Develop brand-new project.

“In the “Produce brand-new job “window, select”ASP.NET Core

Web API “from the list of design templates displayed. Click Next. In the “Configure your new project “window, define the name and area

for the brand-new job.

Optionally examine the”

Place solution and task in the same directory site”check box, depending upon your choices. Click Next.

In the “Additional

Info”window shown next, uncheck the check box that states “Usage controllers …”as we’ll

be using minimal APIs in this example. Leave the” Authentication Type”as “None”( default).

Ensure that the check boxes” Enable Open API Support,””Set up for HTTPS, “and” Enable Docker “are uncontrolled as we won’t be using those features here. Click Create. We’ll utilize this ASP.NET Core 7 Web API

task to deal with SendGrid in the sections below.Why usage SendGrid?SendGrid’s e-mail API makes it simple for developers to incorporate email performance into their applications. You can use the SendGrid API to send emails, track e-mail delivery, and monitor email efficiency.

. Install the SendGrid NuGet bundle So far so good. Now

include the SendGrid NuGet package to your project in

Visual Studio. To do this, pick the job

in the Option Explorer window and right-click and select”Manage NuGet Plans. “In the NuGet Package Manager window, search for the SendGrid package and install it. Alternatively, you can set up the bundle by means of the NuGet Bundle Manager console by entering the line shown below.PM > Install-Package SendGrid Specify SendGrid metadata in the setup file Produce a section called EmailSettings in your application’s configuration file and go into the following

code therein.”EmailSettings “: Make certain to replace”Specify your SendGrid API Secret “with your SendGrid API secret for the SendGrid account you’re using.To bind a circumstances of type EmailSettings to the setup worths, get in the following code in the Program.cs
file. builder.Services.Configure (options=> builder.Configuration.GetSection (“EmailSettings”). Bind( alternatives)); Utilizing SendGrid in ASP.NET Core In this section, we’ll take a look at how we can send out email utilizing SendGrid in ASP.NET

Core.Create the EmailService Class Now, develop a class named EmailService that will be responsible for sending emails using SendGrid. To do this, produce a new.cs submit called EmailService.cs and enter the following code.public class EmailService: IEmailService private readonly IConfiguration _ configuration; personal readonly IOptions _ alternatives; public EmailService(IConfiguration setup, IOptions choices)p>

_ setup=setup; _ choices=alternatives; public async Job SendEmailAsync(string e-mail, string topic, string htmlMessage)string? fromEmail =_ options.Value.SenderEmail; string? fromName=_ options.Value.SenderName; string? apiKey=_ options.Value.ApiKey

; var sendGridClient=brand-new SendGridClient (apiKey); var from=new EmailAddress (fromEmail, fromName); var to= new EmailAddress (email); var plainTextContent =Regex.Replace(htmlMessage,”< [^ >] * >”,”” ); var msg=MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlMessage); var reaction=await sendGridClient.SendEmailAsync(msg); Keep in mind how the Options pattern has been used here to obtain the email metadata from the application setup file.Create the EmailController class Develop a brand-new API controller in your job called EmailController. In your controller, inject a circumstances of type EmailService and call the SendEmailAsync approach: [Path (“api/ [controller])] [ApiController]. public class EmailController: ControllerBase. personal readonly IEmailService _ emailService; private readonly ILogger _ logger; public EmailController(IEmailService emailService, ILogger logger)_ emailService=emailService; _ logger = logger; [. HttpGet] public async Task Get() await _ emailService.SendEmailAsync(” [email protected]”,”Some subject”, “Define the html material here”); return Ok();. Now include a Singleton service of type IEmailService by consisting of the following code in

the Program.cs file.builder.Services.AddSingleton( ); That’s it! When you run your application and execute the HttpGet action of your EmailController,
