Better way of setting input scope on text box in WP7
I'm not really sure what you want from this, if all you want is to make it more readable, then a few well placed new-lines will make a world of difference. If you want to reduce the amount of code, I don't think there is much room for that other than switching constructors for InputScopeName.

txtBox.InputScope = new InputScope
{
    Names =
    {
        new InputScopeName(InputScopeNameValue.Text)
    }
};


Note: Text does not appear to be a valid member of InputScopeNameValue, but ill keep it for the sake of consistency with the question.
