In C it's called a variable-length struct or object. I don't
think D implements them, but this could probably work:
struct Foo {
size_t len;
ubyte[] data() @property {
auto thisptr = cast(ubyte*)();
return thisptr[Foo.sizeof..(Foo.sizeof+len)];
}
}

I tried that on my windows console and i got the error that the command 'dub' can't be found. If i try: 'dub.json build' it just opens the dub.json file in my default .json program. The only reason i want to use Tango is that i would like to read and send data from/to a serial COM port and i don't want to mess around with importing C libraries.

It's a long dead site, maintained now only in read-only mode because it still has some stuff worth keeping around. I remember trying to read through an in-depth manual to how to use Tango, and I felt it had an over-emphasis on templates without having/showing simple examples of how to use the libraries (or users not wanting to use templates). It eventually made me drop from trying to use any of the Tango library. Much like the Java documentation where I recall similar issues (but with java with some of the libraries I wanted to use, it was referencing abstract classes). Although it's been several years since I looked much into either of those very closely, and I can't recall exact examples to show what I mean.
