Software

This is the software that will need to be installed onto your machine.

• Visual Studio 2026. Version 18.0.0 or above. It will work with the free community version.

• .NET 10 SDK. Version 10.0.0 or above.

The application

Open up RoundTheCode.SendEmail.slnx. The solution has three projects:

Application

This is a Razor class library that contains common classes and the Razor view email templates located in Views/Email.

Web

This is an ASP.NET Core Web API.

When it starts, it will load https://localhost:7247/send-email, which will render the order confirmation email template.

You can also open https://localhost:7247/send-email/new-order, which will render the new order email template.

The email content is generated from the views located in Views/Email from the Application project. It's generated as an HTML string using EmailHelper.GetEmailContentAsync, which is also located in the Application project.

Worker

This is a background worker service. 

When it starts, it will run the EmailWorker hosted service. This runs every 60 seconds and will render both the order confirmation and new order email templates to the log.

Like the Web project, the email content is generated from the views located in Views/Email from the Application project, and is generated as an HTML string using EmailHelper.GetEmailContentAsync.
