Cross.Messaging

A set of libraries for sending messages across multiple channels.

Current focus:

  • Email (Cross.Messaging.Email.*)
  • SMS (Cross.Messaging.Sms.*)
  • Telegram (Cross.Messaging.Telegram.*)
  • Viber (Cross.Messaging.Viber.*)
  • WatsApp (Cross.Messaging.WatsApp.*)

Supported targets: .NET Standard 2.1, .NET 6, .NET 7, .NET 8, .NET 9, .NET 10

Install NuGet package

Install the Cross.Messaging NuGet package into your .NET project:

Install-Package Cross.Messaging

or

dotnet add package Cross.Messaging

Quick start

Register the email sender in DI

services.AddEmailSender(configuration);

AddEmailSender:

  • binds the MessagingEmail configuration section to MessagingEmailOptions
  • registers IEmailSenderService → EmailSenderService (scoped)

Email sender API

IEmailSenderService currently exposes:

  • SendAsync(toName, toEmail, subject, body, cancellationToken)
  • SendAsync(toName, toEmail, subject, textBody, htmlBody, attachments, cancellationToken)
  • SendAsyncWithContentIds(toName, toEmail, subject, textBody, htmlBody, attachments, contentIdMap, cancellationToken)

If you use attachment overloads, pass IReadOnlyCollection<IFormFile>? (Microsoft.AspNetCore.Http).

Example:

await emailSender.SendAsync(
    toName: "User",
    toEmail: "user@example.com",
    subject: "Hello",
    textBody: "Plain text body",
    htmlBody: "<p>HTML body</p>",
    attachments: null,
    cancellationToken: cancellationToken);

Sample email configuration

{
  "MessagingEmail": {
    "SmtpHost": "smtp.example.com",
    "SmtpPort": 587,
    "UseSsl": true,
    "SecureSocket": "StartTls",
    "SmtpLogin": "login",
    "SmtpPassword": "password",
    "FromUserName": "App Messaging",
    "FromUserAddress": "no-reply@example.com",
    "RecipientOverride": ""
  }
}

Unit tests

Tests use the Given_When_Then naming style:

  • Given — context and preconditions.
  • When — the action under test.
  • Then — the expected outcome.

Example: Given_ValidSmtpOptions_When_SendAsync_Then_UsesConfiguredHost.

Tests live in Cross.Messaging.Tests/ (for example Email/, Sms/).

Code coverage

Run tests with code coverage (opencover):

dotnet test Cross.Messaging.Tests/Cross.Messaging.Tests.csproj \
