JsonConsoleLogger and SimpleConsoleLogger do not support BeginScope

I wrote the following code and was expecting, that the logger will write the scope keys (in my example key, JobId and fileName inside the logging. When I checked the logging on the UI the keys are not written.

using (this._logger.BeginScope(new Dictionary<string, object> { ["key"] = "1234567890123", ["jobId"] = 54 }))
{
    this._logger.LogTrace("Test Log - Scope Map - Trace");
    this._logger.LogDebug("Test Log - Scope Map - Debug");
    this._logger.LogInformation("Test Log - Scope Map - Information");
    this._logger.LogWarning("Test Log - Scope Map - Warning");
    this._logger.LogError("Test Log - Scope Map - Error");
    this._logger.LogError(new Exception("My Error Exception"), "Test Log - Scope Map - Error with Exception");
    this._logger.LogCritical("Test Log - Scope Map - Critical");
    this._logger.LogCritical(new Exception("My Critical Exception"), "Test Log - Scope Map - Critical with Exception");

    using (this._logger.BeginScope(new Dictionary<string, object> { ["fileName"] = "Test.txt" }))
    {
        this._logger.LogTrace("Test Log - Scope File - Trace");
        this._logger.LogDebug("Test Log - Scope File - Debug");
        this._logger.LogInformation("Test Log - Scope File - Information");
        this._logger.LogWarning("Test Log - Scope File - Warning");
        this._logger.LogError("Test Log - Scope File - Error");
        this._logger.LogError(new Exception("My Error Exception"), "Test Log - Scope File - Error with Exception");
        this._logger.LogCritical("Test Log - Scope File - Critical");
        this._logger.LogCritical(new Exception("My Critical Exception"), "Test Log - Scope File - Critical with Exception");
    }
}

Maybe it could be an option to include a third logger in the framework, where an output format string can be set via dependency injection. Inside this format string, the scope properties could be used when they are set.

Example: “{scope:jobId} {scope:key} {message}”

Alternatively the logger could write the scope to the JsonPayload.

(In fact, writing the scopes to a separate line in the output, in the same way that we do for exceptions, might make it sufficiently non-chatty… same amount of information, but clearer. Will give that a go.)

Right, this will be in the next release - I’m going to see which other issues I can pick off before we do a release though.
