How to setup ElmahCore for a Console Application?

Question

I want to log errors for a console application using Elmah.I've found ElmahCore and elmah.io.core but I don't know how to setup any of them on a console app.I'm using .net core.

ELMAH (the open source project) doesn't work with .NET Core. ElmahCore has a lot of dependencies to ASP.NET Core, but if you really wanted to, you could do something like this:

class Program
{
    static void Main(string[] args)
    {
        var log = new MemoryErrorLog();
        log.Log(new Error(new Exception()));
        var errors = new List<ErrorLogEntry>();
        var result = log.GetErrors(0, 10, errors);
        Console.WriteLine(result);
        Console.WriteLine(errors);
        Console.ReadLine();
    }
}

You can replace MemoryErrorLog with a target logger of your choice.

The package named elmah.io.core is a deprecated package from elmah.io. elmah.io is (among other things) a commercial cloud version of ELMAH, where you store all of your errors in the cloud (list of differences between ELMAH and elmah.io). elmah.io works with .NET core through either the Elmah.Io.Client NuGet package or using one of the integrations for popular logging frameworks like Serilog and NLog.

I wouldn't recommend you to use ElmahCore for logging in a console application. It is created for ASP.NET Core. There are much better options for logging from a console application, like the mentioned logging frameworks.
