NLog.Targets.AppCenter

NLog Target for Microsoft Visual Studio App Center with Azure

⚠️ Microsoft AppCenter will be retired - https://learn.microsoft.com/appcenter/retirement

How to setup NLog in MAUI

1) Install the NLog packages

• Install-Package NLog.Targets.AppCenter

• Install-Package NLog.Extensions.Logging

  or in your csproj:

  <PackageReference Include="NLog.Targets.AppCenter" Version="5.*" ></PackageReference>
  <PackageReference Include="NLog.Extensions.Logging" Version="5.*" ></PackageReference>

2) Add NLog to the MauiApp

Update MauiProgram.cs to include NLog as Logging Provider:

   var builder = MauiApp.CreateBuilder();
   // Add NLog for Logging
   builder.Logging.ClearProviders();
   builder.Logging.AddNLog();

If getting compiler errors with unknown methods, then update using-section:

   using Microsoft.Extensions.Logging;
   using NLog;
   using NLog.Extensions.Logging;

3) Load NLog configuration for logging

Add the NLog.config-file into the Application-project as assembly-resource (Build Action = embedded resource), and load like this:

   NLog.LogManager.Setup().RegisterAppCenter()
       .LoadConfigurationFromAssemblyResource(typeof(App).Assembly);

Alternative setup NLog configuration using fluent-API:

   var logger = NLog.LogManager.Setup().RegisterAppCenter()
                    .LoadConfiguration(c => c.ForLogger().FilterMinLevel(NLog.LogLevel.Debug).WriteToAppCenter())
                    .GetCurrentClassLogger();
