I am trying to use FluentEmail 2.8.0 in an Azure Function. However, I had the following exception.

RazorLight.RazorLightException: Can't load metadata reference from the entry assembly. Make sure PreserveCompilationContext is set to true in *.csproj file

I have added the following into csproj

<PropertyGroup>
    <FunctionsSkipCleanOutput>true</_FunctionsSkipCleanOutput>
</PropertyGroup>

<PropertyGroup>
    <PreserveCompilationReferences>true</PreserveCompilationReferences>
    <PreserveCompilationContext>true</PreserveCompilationContext>
</PropertyGroup>

But I still get the same error.

Anyone has come across this before?

Environment: .NET Core 3.1, Azure Functions v3

At least I am able to find a workaround.

  1. Do not use the razor renderer from fluent email factory

  2. Use the following

             var engine = new RazorLightEngineBuilder()
                     .UseEmbeddedResourcesProject(typeof(EmailService))
                     .UseMemoryCachingProvider()
                     .SetOperatingAssembly(Assembly.GetExecutingAssembly())
                     .Build();
         var result = engine.CompileRenderStringAsync(templateName, template, viewModel);

...

then use _fluentEmail.Create()...Body(result, true)

add the missing nuget package System.Threading.AccessControl also.
