Hi Tobias,

After some time, I had the chance to look at this thing again:

My question is, when I have more than a few parameters to state, how can 
I achieve that?

Now it is

Return ["name": txtName.Text, "password": txtPassword.Text]

but when I have 200 or more things to pass? Or is the collection thing 
too slowly for such a number of items?
