Okay someone be a pal and remind me ... 


We're upgrading from Autocad 2011 32 bit Win XP

to Autocad 2011 64 bit Windows 7. 


What do I need to do with my .NET plugins which were done in Visual Studio 2008...

Or post the link to the web-site I need to read... 


Appreciate the help.

If you compiled them with "Any CPU" as the target platform, you probably won't have to do anything, unless you are PInvoking ARX functions which will have a different signature in 64 bit.


If you compiled them to x86 platform, you will need to recompile them (I suggest to Any CPU).


There are some cases where a referenced assembly may only work with 32 bit (like the Jet ODBC engine, I think).  This is probably the only thing that can prove to be a real problem, because in some cases there is no 64 bit version available.

The other one is if you're working with tables. Can't recall exactly what it was but there is something where handling of object ID's within tables is different between 32- and 64-bit.
