Logging to elmah.io from Uno

Integrating Uno with elmah.io is done by installing the Elmah.Io.Uno NuGet package:

Install-Package Elmah.Io.Uno -IncludePrerelease

dotnet add package Elmah.Io.Uno --prerelease

<PackageReference Include="Elmah.Io.Uno" Version="4.0.19-pre" />

paket add Elmah.Io.Uno

While configured in the shared project, the NuGet package will need to be installed in all platform projects.

Elmah.Io.Uno comes with a logger for Microsoft.Extensions.Logging. To configure the logger, open the App.xaml.cs file and locate the InitializeLogging method. Here you will see the logging configuration for your application. Include logging to elmah.io by calling the AddElmahIo method:

var factory = LoggerFactory.Create(builder =>
{
    // ...
    builder.AddElmahIo("API_KEY", new Guid("LOG_ID"));
    // ...
});

Replace API_KEY with your API key (Where is my API key?) and LOG_ID (Where is my log ID?) with the log Id of the log you want to log to.

elmah.io will now automatically log all warning, error, and fatal messages to elmah.io. Uno log messages internally, but you can also do manual logging like this:

this.Log().LogWarning("Oh no");

Logging with Uno's log helper will require you to add the following usings:

using Microsoft.Extensions.Logging;
using Uno.Extensions;
