Xamarin Forms: Logging with anything from Console to SQLite

And it’s also logging the invoked method name, and the file name containing the method!

My Forms.RecurrenceToolkit NuGet package pack is now extended with logging functionality.

You can use the pre-written Console and SQLite logger without writing much code, or you can implement your own logger in a few lines, and use it instantly simultaneous with other loggers.

Install banditoth.Forms.RecurrenceToolkit.Logging.* packages, and enjoy the painless logging, and focus on the great ideas instead of being a copy paste robot. 🙂


In your App.xaml.cs, initalize the logger like:

	// If you have installed the console logger:
	new ConsoleLogger(),
	// If you have installed SQLite Logger:
	new SQLiteLogger()

The logger is including the calling method’s name, and the .cs file name in the logs. You can access the logger from anywhere by calling these methods:

LoggingProvider.LogCritical("It's a critical message");
LoggingProvider.LogDebug("It's a debug message");
LoggingProvider.LogError("It's an error message");
LoggingProvider.LogException(new Exception(), "It's an exception");
LoggingProvider.LogInformation("It's an information message");
LoggingProvider.LogTrace("It's a trace message");
LoggingProvider.LogTrace(new StackTrace());
LoggingProvider.LogWarning("It's a warning message");

By default, the console and the SQLite logger logs exceptions in error level.

You can implement your own logger by deriving from BaseLogger class, like:

public class CustomLogger : BaseLogger
		public CustomLogger() : base(new LoggerOptions()
			IncludeCallerSourceFullFileName = true, // This will print C:/Users/Path/AssemblyFile.cs
			IncludeCallerSourceShortFileName = false, // This will print AssemblyFile.cs
			ExceptionLevel = Enumerations.LogLevel.Error, // The LogExceptions calls routed to log to the loglevel set.
			IncludeCallerMethodName = true // This can print the calling method's name

		public override void LogCritical(string criticalMessage, string callerMethod, string filePath)
			// Your own method

		// .. File continues

Xamarin and Aspect Orientated Programming

I have started implementing my very first AOP like library, which is now available for testing in NuGet.org as a pre-release version.

This package is a part of my Xamarin.Forms Toolkit, and it is a good time to say thank you for using all of the three packages more than 500 times.
When I had published them, I thought the only user will be me. 🙂

In the first release of the package (1.0.0-pre-01), you can decorate your methods with attributes, in order to listen for Entering the method, and Exiting the method.

This can be handy for example, when you need to log your method invocations (Firebase analytics, Basic logging) or when you need to measure the elapsed time of the method run.

    public void BoringMethod()

For example, the following code above will result the output below:

yaaay on enter!
2021. 05. 25. 16:56:01
yaaaay on exit

This can be achieved implementing IMethodDecorator class like this:

    public class ConsoleYaay : Attribute, IMethodDecorator
        public ConsoleYaay()


        public void OnEnter()
            Console.WriteLine("yaaay on enter!");

        public void OnExit()
            Console.WriteLine("yaaaay on exit");

Future improvements

This package can be improved in a lot of aspects, so stay tuned for more details. Or just simply make a pull request with your ideas 🙂

Xamarin Forms: MVVM Navigation, Converters, Multi-language all in one place

A toolkit for Xamarin.Forms, inspired by hours of hours re implementation of the same navigation logic, converters, and the other tools needed to build a mobile app idea.


I’ve published my first NuGet collection, which contains a lot of code, from MVVM Navigation through Bindable objects implementing INotifyPropertychanged, and XAML Converters, Multi-language tools.

Forms.RecurrenceToolkit has arrived

And can be downloaded from NuGet.org.

Feel free to contribute at GitHub.

Have a great app building!
