Ran into a few issues, starting out with added @page in the razor pages. Doing so result in null exceptions
Unhandled Exception: System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.) ---> System.NullReferenceException: Object reference not set to an instance of an object.

but looking at entropy example i found that @page should not be used.
Also, when moving things to a templates folder instead of views, the partial and layouts needs to be in 'templates/shared' folder instead of the root views folder. I have not found a way to config this.
But everything works now and running will give the template rendered 3 times, first for the default, second for a template in a shared library and last using a seperate rendering abstracting also in a seperate class library.
public static void Main()
{
var serviceScopeFactory = InitializeServices();
{
var emailContent = RenderViewAsync(serviceScopeFactory, "Templates/EmailTemplate.cshtml").Result;
Console.WriteLine(emailContent);
}
{
var emailContent = RenderViewAsync(serviceScopeFactory, "Templates/WelcomeMail.cshtml").Result;
Console.WriteLine(emailContent);
}
{
var a = new EmailTemplateService();
Console.WriteLine(a.RenderViewAsync().Result);
}
}
output:
