Does AnsiConsole support message templates?

[pedroduarte0]

Hi,

Does AnsiConsole support message templates, as described over https://learn.microsoft.com/en-us/aspnet/core/fundamentals/logging/?view=aspnetcore-7.0#lmt ?

Looking at the 'AnsiConsole.WriteLine(string format, params object[] args)' I thought it does, but I am getting an 'System.FormatException: 'Input string was not in a correct format.' exception so I guess it doesn't?

Below you can find a code example that tries to clarify my question. Please create a C# console application, add the two nuget packages "Microsoft.Extensions.Logging.Console" and "Spectre.Console" and try out this sample:

Thank you in advance

using Spectre.Console;
using Microsoft.Extensions.Logging;

namespace SpectreConsole_MessageTemplateTest
{
    /// <summary>
    /// Quick and dirty try out of possible AnsiConsole.WriteLine message templates support.
    /// </summary>
    internal class Program
    {
        private static ILogger<Program> _logger;

        static void Main(string[] args)
        {
            var loggerFactory = LoggerFactory.Create(builder =>
            {
                builder.AddFilter("Microsoft", LogLevel.Warning)
                       .AddFilter("System", LogLevel.Warning)
                       .AddFilter("SampleApp.Program", LogLevel.Debug)
                       .AddConsole();
            });
            
            _logger = loggerFactory.CreateLogger<Program>();
        
            WriteMessage("It is {todayTime}. Exacty 24 hours ago it was {yesterdayTime}.", DateTime.Now.ToString(), DateTime.Now.AddDays(-1).ToString());
        }

        static void WriteMessage(string message, params object[] args)
        {
            _logger.LogWarning(message, args);

            AnsiConsole.WriteLine(message, args);     // Gets an 'System.FormatException: 'Input string was not in a correct format.'
        }
    }
}

@pedroduarte0 No, AnsiConsole.WriteLine is analog to Console.WriteLine.
