Hi,

I am looking at migrating a package i have on v8 and wondering if i can do some multi-targeting in the project so i have one code base ?

I have an example of this working for the linkedpages package. ( https://github.com/KevinJump/Our.Umbraco.LinkedPages/tree/dev/shared ) for a lot of not to "technical inside Umbraco stuff", you can get away with #ifdef blocks around using statements.

e.g the controller for that package has :

#if NETFRAMEWORK
using System.Web.Http;
using Umbraco.Core;
using Umbraco.Core.Models;
using Umbraco.Core.Models.Entities;
using Umbraco.Web.Mvc;
using Umbraco.Core.Services;
using Umbraco.Web.WebApi;
#else
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;

using Umbraco.Cms.Core;
using Umbraco.Cms.Core.Models;
using Umbraco.Cms.Core.Models.Entities;
using Umbraco.Cms.Core.Services;
using Umbraco.Cms.Web.BackOffice.Controllers;
using Umbraco.Cms.Web.Common.Attributes;
#endif

So i was going to try this approach on another project, but i have quite a few logging lines, through the code (it really helps to have logging in packages, for when people tell you they are having issues, but you do not have access to their site!).

So for example i will inject ILogger (from Umbraco.Core.Logging). into a service and call the logger.

logger.Debug<MyService>("Something logged {value}", value); 

in v9 you inject ILogger<MyService> (from using Microsoft.Extensions.Logging;) and the call is

logger.LogDebug("Something logged {value}", value); 

now if i have shared code across a project it would be great if i could have the same logger lines in the code for both versions (and #ifdef around each log line seems fugly)

real questions are :

• can i / should i go to the base serilog interface and use that logger which i am guessing is the same between v8 and v9 ?
• should i look at wrapping the logging so the same call can be made in each version -and the diffrences are in a method somewhere else ?

is there some super neat trick i am missing that would make this bit super simpler ☺
