.Net Core custom log-message format-CodePudding

Is it possible to override or customize the built in logger in .net core to have a special formatted message?

For example, when doing some logging:

class A
{
    private readonly ILogger<A> _logger;
    public A(ILogger<A> logger)
    {
        _logger = logger;
    }

    public DoStuff()
    {
        _logger.LogInformation("Start of function");
    }
}

The problem is, I would like to have the message end up like this:

7/4/2022 Start of function 123456789

In other words maybe some prefixes, suffixes, all in uppercase or something else. And I want ALL the logging messages to be in the same way without me building them all the time (and of course I don't want to do it using a function either like _logger.LogInformation(func("Start of function"))).

You can use logger factory

ILoggerFactory loggerFactory =
            LoggerFactory.Create(builder =>
                builder.AddSimpleConsole(options =>
                {
                    options.IncludeScopes = true;
                    options.SingleLine = true;
                    options.TimestampFormat = "hh:mm:ss ";
                    options.CustomPrefix = " ~~~~~ ");
                }));
