Could not load type 'Microsoft.Extensions.Logging.Internal.FormattedLogValues'

[JonasJasas]

Adding this code to hello world core mvc project:

public void ConfigureServices(IServiceCollection services)
{
    var options = new LogDNAOptions("xxxxxxxxxxxxxxxxxxxxxx", LogLevel.Debug).AddWebItems();
    services.AddLogging(loggingBuilder => loggingBuilder.AddLogDNA(options));

    services.AddRazorPages();
}

Getting an error:

Unhandled exception. System.AggregateException: An error occurred while writing to logger(s).

I have the same problem
TypeLoadException: Could not load type 'Microsoft.Extensions.Logging.Internal.FormattedLogValues' from assembly 'Microsoft.Extensions.Logging.Abstractions, Version=3.1.8.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

@JonasJasas it looks like this library was built for netcore 2.0. In 3.0 the type FormattedLogValues is made internal and can't be accessed. I was able to make it work by extending the library and I can see my logs into the logsDNA. I might be able to make a PR here for this library these days :)
