Topic: comparing dll files from varies autocad versions

[efernal]

Need to know about the files AcDbMgd.dll an AcMgd.dll
I defined a vb.net command in 2006 (ms 2008). It runs ok
in 2006, would run in 2007?

Also, I compile the same code with Autocad 2010 using 2010
AcDbMgd.dll and AcMgd.dll. It works in 2008, 2010 (already tested)
Would run in AutoCAD 2009 and 2011?

Could someone fill the blanks bellow, please?

Thanks in advance...

autodesk allways changes this files...

Each new AutoCAD release come with some new features, so the .NET libraries come with some new APIs.

AFAIK, most of the .NET programs compiled against 2007 librairies work fine with upper AutoCAD versions. By my side, I only noticed the Drawable abstract class implementation changed with 2010 (see here) and some methods which requiered Int64 type arguments prior to 2011 that requires IntPtr type arguments since 2011.

From what I understood, the '.NET philososphy' is to keep compatibility from older versions to newer ones (each new Framework add new features but dont modify the previous ones). It looks like Autodesk does not strictly respect this...

Maybe someone which speak a better English and have a better .NET knowledge than me can explain this a better way (or correct me).

Maybe in the right forum too...
