Additional information

.NET Framework 4.x versions are in-place updates to earlier versions. That means the following:

  • You can only have one version of the .NET Framework 4.x installed on your machine.

  • You cannot install an earlier version of the .NET Framework on your machine if a later version is already installed.

  • 4.x versions of the .NET Framework can be used to run applications built for the .NET Framework 4.0 through that version. For example, .NET Framework 4.7 can be used to run applications built for the .NET Framework 4.0 through 4.7. The latest version (the .NET Framework 4.8) can be used to run applications built with all versions of the .NET Framework starting with 4.0.

For a list of all the versions of the .NET Framework available to download, see the .NET Downloads page.


If you cannot get the correct version of the .NET Framework installed, you can contact Microsoft for help.

In the previous tutorial (Fat Free Framework – 1. Installing Fat Free Framework…), we tested the installation of Fat Free Framework by creating a route that was calling an anonymous function when someone was accessing the application:

echo'hello from f3!';

But if we do this for every “page” that someone access the main index.php file would become pretty large soon.

So why not create classes that would deal with different routes?

For starters, let’s change the line above with this and see if it works?

Now, if we visit the same page again, we will see that everything works fine.

As you can see, we can pass our route a controller (class) and a method by using the classic notation class->method.

All we have to do now is to move the class in its own file… So how do we do this?

So let’s create an “App/Controllers” directory and in it create a file named Homepage.php and put the class definition in it:

Now we will use the autoload system variable AUTOLOAD (https://fatfreeframework.com/quick-reference#AUTOLOAD). This allows us to define file that the framework will attempt to autoload at runtime. That means that if we pass it our app directory, any class called inside our application will be looked inside this directory.

So returning to our index.php we will ask the autoload functionality to take into consideration our app directory, by using the set() method to our instance:

Now, if we visit our website again we will see that… nothing happened… which is… good…

Let’s see the index.php again:

$f3->route('GET /','Homepage->index');

Now let’s see our App/Controllers/Homepage.php

echo'hello from index';

See you next time.
