network stream AvailElmntsForRead return bad value

[yipilipi]

I'm doing some test with network stream , i'm using networkstream with array of 500 double as element. 

I write 2 elements (2 array of 500 on the stream) . Then wait that element are written.

Then i check the reader for AvailElmntsForRead. The value of this property must be 2 but is actually 500.

I've checked the documentation but i don't find any explanation for this.
