When i try to use a blue mask for a random color like this:

Color.FromArgb( myrand.next() & 0xff0000ff )

I get an error: 0xff0000ff can't be converted to int.

Apparently maximum value for int32 is 7fffffff, so how am I to set the
alpha part to ff ?

You can cast to int in an unchecked context:

unchecked((int)0xff0000ff)
