Difference between variable using and statement using?

Im just wondering if there is any difference to using a

using

using

using

using statement by doing this:

using var foo = new Bar();
foo.DoStuff();

using var foo = new Bar();
foo.DoStuff();

using var foo = new Bar();
foo.DoStuff();

using var foo = new Bar();
foo.DoStuff();

as opposed to doing

using (var foo = new Bar())
{
    foo.DoStuff();
}

using (var foo = new Bar())
{
    foo.DoStuff();
}

using (var foo = new Bar())
{
    foo.DoStuff();
}

using (var foo = new Bar())
{
    foo.DoStuff();
}

Only difference is that using (var foo = new Bar())using (var foo = new Bar()) creates a new scope, at the end of which foofoo is disposed. Using using var foo = new Bar();using var foo = new Bar(); will dispose foofoo at the end of the method.

so there isnt really any performance or memory difference?

Also the simple using statement still disposes at the end of the current scope

That might be the end of the method, or it might not
