:heavy_check_mark: Configuring EF Core logging from appsettings.json

**Options** for logging

```csharp

public enum LoggingDestination

{

    /// 

    /// Log to Output window

    /// 

    DebugWindow,

    /// 

    /// Log to file

    /// 

    LogFile,

    /// 

    /// No logging

    /// 

    None

}

```

**Usage**: reads [appsettings.json](https://github.com/karenpayneoregon/ef-core5-logging/blob/master/LogToFile/appsettings.json)

```csharp

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)

{

    if (!optionsBuilder.IsConfigured)

    {

        switch (Helper.LoggingDistination())

        {

            case LoggingDestination.DebugWindow:

                LogQueryInfoToDebugOutputWindow(optionsBuilder);

                break;

            case LoggingDestination.LogFile:

                LogQueryInfoToFile(optionsBuilder);

                break;

            case LoggingDestination.None:

                NoLogging(optionsBuilder);

                break;

            default: throw new ArgumentOutOfRangeException();

        }

    }

}
