Difference between variable using and statement using?

Im just wondering if there is any difference to using a using statement by doing this:
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();
}

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

No 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
