Setup
--------------------------------------------------------------------------

First, you need to get an API key, which is available in the
[Resend Dashboard](https://resend.com/).

In the startup of your application, configure the DI container as follows:

```csharp
using Resend;

builder.Services.AddResend( o => 
{
    o.ApiToken = Environment.GetEnvironmentVariable( "RESEND_APITOKEN" )!;
} );
```

You can then use the injected `IResend` instance to send emails.

Usage
--------------------------------------------------------------------------

Send your first email:

```csharp
using Resend;

public class FeatureImplementation
{
    private readonly IResend _resend;

public FeatureImplementation( IResend resend )
    {
        _resend = resend;
    }

public async Task Execute()
    {
        var message = new EmailMessage();
        message.From = "onboarding@resend.dev";
        message.To.Add( "delivered@resend.dev" );
        message.Subject = "hello world";
        message.TextBody = "it works!";

await _resend.EmailSendAsync( message );
    }
}
```

Send email using HTML
--------------------------------------------------------------------------

Send an email custom HTML content:

```csharp
using Resend;

public class FeatureImplementation
{
    private readonly IResend _resend;

public FeatureImplementation( IResend resend )
    {
        _resend = resend;
    }

await _resend.EmailSendAsync( message );
    }
}
```
