    Greets,

        While I've not run across it, there may be a way to make one of your
    class library DLLs automatically referenced by the Visual Studio .NET IDE.
    Certain project types add references to other .NET DLLs (such as the
    System.Web.dll), so perhaps you could create a custom project type that adds
    your control library. (Note that if you create, say, a console application,
    you have to add that reference yourself.)

        This is definitely not recommended (i.e. don't do it for production
    code!), but one MC++ project I worked on used the System namespace to
    declare a "ConsoleEx" class with static members that were meant to augment
    the .NET Framework Console functions. It would definitely be frowned upon
    for a production release, especially if there were ever a class with that
    name to be added to the framework, but it worked for me nonetheless. (I
    only used it for internal testing as a way to 'cheat' without needing a
    'using' statement specifically for that class.)

        As far as multi-threading is concerned, you only have an issue if you
    have static data members which are accessed by your static member functions.
    In that case, you would have to lock access to them between threads. If,
    however, you take all your parameters to your static member functions and
    create any interim objects and data internally (without any static members
    or variables [i.e. everything on the stack or heap and not shared between
    threads]) then you should have no problems running in a multi-threaded
    environment without any special synchronization considerations.

    Regards,

    Joe

      ... However, a function can pass back arbitrarily many values, via a variety of mechanisms, including the return value, passing variables by reference, and passing reference types by value, all of which can be used simultaneously. ...

This may be related to the previous issue, since the CalcolaPercentuale() function uses the static members; perhaps you meant to use the parameters "a" and "b" instead of the static members. ...
