.NET 8.0 Web API - UsingTemplateFromFile cannot find email template file

[alonstar]

Hi everyone,

I am developing a .NET 8.0 Web API and trying to use UsingTemplateFromFile to parse an email template. However, the application throws an exception indicating that it cannot find the template file.

Here is my code setup:

builder.Services
        .AddRazorRenderer(Path.Combine(AppContext.BaseDirectory, "EmailTemplates"))
        .AddSmtpSender(new SmtpClient(smtp["Host"])
        {
            Port = int.Parse(smtp["Port"]),
            Credentials = new NetworkCredential(smtp["Username"], smtp["Password"]),
            EnableSsl = bool.Parse(smtp["EnableSsl"])
        });

This is not working.

var email = fluent
                .To("admin@gmail.com")
                .Subject("test")
                .UsingTemplateFromFile("WelcomeTemplate.cshtml", new Data());

This is working.

var email = fluent
                .To("admin@gmail.com")
                .Subject("test")
                .UsingTemplateFromFile("EmailTemplates/WelcomeTemplate.cshtml", new Data());

And the error is
System.IO.FileNotFoundException: Could not find file 'C:\Users\xxx\WebApi\WelcomeTemplate.cshtml'.

It looks like the default root is not working, did I do something wrong?
