如何以编程方式注册Nlog扩展/布局渲染器（NLog.Web.AspNetCore）？

Question

There is a guide here that uses a configuration file to register NLog for ASP.Net Core. I have followed it, but I'd like to configure things programmatically. Mostly everything works, but I cannot get ASP.Net Core layout renderers to work. They do work if I register them myself like this:

LayoutRenderer.Register("aspnet-request-url", typeof(AspNetRequestUrlRenderer));

I see that in file configuration there is a section for that:

<!-- enable asp.net core layout renderers -->
<extensions>
   <add assembly="NLog.Web.AspNetCore"/>
</extensions>

But I cannot figure out how to do that programmatically for all renderers that are in that assembly.

Answer 1

You could do that as follows:

ConfigurationItemFactory.Default.RegisterItemsFromAssembly(assembly);

So for NLog.Web.AspNetCore:

var assembly = typeof(AspNetRequestUrlRenderer).Assembly;
ConfigurationItemFactory.Default.RegisterItemsFromAssembly(assembly);
