Hi,
For each new version i'm preparing the Hebrew version for developers in israel.
The reason is that dnn is not supporting right to left languages.
So for every version i add this attribute to the container.vb code:

Public ReadOnly Property textDirection() As String...

And for each container i add in the table tag:
dir="<%=textDirection%>"

When i add that property and compiled the code i noticed that change did not affect the portal.
I noticed that for the library folder there is another BIN directory.
I copied the assembly DOTNETNUKE.dll from library/bin to the "web site" bin directory - then it worked.

Why changes in "library" code does not affect the code immediately?
What the purpose of being more than one BIN directory?
Did i act correctly by copying this assembly?

Thanks.
