⚠️ Not all targets and layout renders are implemented for .NET Standard. See the Platform support table

There is a special package for ASP.NET Core / MVC Core. This is needed because HttpContext.Current isn't available in ASP.NET Core and we can't detect if ASP.NET or ASP.NET Core is used. The package depends on NLog.Extensions.Logging

The following parts are supported in ASP.NET Core:

• ${aspnet-Item} - ASP.NET HttpContext item variable.
• ${aspnet-Request} - ASP.NET Request variable. (except ServerVariable)
• ${aspnet-Session} - ASP.NET Session variable.
• ${aspnet-SessionId} - ASP.NET Session ID variable.
• ${aspnet-User-AuthType} - ASP.NET User auth.
• ${aspnet-User-Identity} - ASP.NET User variable.
• ${iis-site-name} - IIS site name.

	</modules>
