Getting error loading file or assembly using latest FluentEmail 2.5.1

[leniel]

Hello,

I have the following packages installed:

  <package id="FluentEmail.Core" version="2.5.1" targetFramework="net472" />
  <package id="FluentEmail.Razor" version="2.5.1" targetFramework="net472" />
  <package id="FluentEmail.Smtp" version="2.5.2" targetFramework="net472" />

RazorLight is version alpha-3:

<package id="RazorLight" version="2.0.0-alpha3" targetFramework="net472" />

When trying to send an e-mail with a template like this one:

public async Task SendEmail()
{
    var template = "Dear @Model.Name, You are totally @Model.Compliment.";

    email.To(configuration["emailTo"])
        .Subject("Test e-mail")
        //.Body("Test");
        .UsingTemplate(template, new { Name = "Leniel Maccaferri", Compliment = "Awesome" });

    await email.SendAsync();
}

it fails with:

Well... I just took a look at the project's bin folder and System.Runtime is not there even though It has Copy Local = true...

What could be the problem?

This should be fixed by Razorlight's 2.0.0-beta1. I've pushed version FluentEmail.Razor 2.5.2 to include it. Can you please try that and let me know if it solves the problem?

Hi Ben,

Just installed the new NuGet package... this time the installation went well. However, when running the code I get an exception {"Object reference not set to an instance of an object."} related to RazorLight.

FYI: I'm trying this using a .NET Framework 4.7.2 Console Application.

@leniel I have the same issue. This bug was also noted on the RazorLight tracker; it was Closed pending a fix in the next release.

Is there any temporary solution?
