Sorry, I was/am kind of busy lately, I unfortunately didn't look at this thread for a while !

I also experienced the error you mentioned under VS 2010, i uploaded a fix for VS 2010 on the acknexwrapper.matthias-auer.net homepage !

I also hope to upload a beta version of the new wrapper (only for 7.8x atm) in the next days (hopefully not weeks) - if i find enough time !

The new wrapper won't use unsafe code anymore, the usage of strings will be improved and won't use a var object, only normal doubles and ints, and the engine objects like ENTITY will have class methods which are the corresponding functions in lite-c like ent_create (although I'm not quite sure whether this will prove to be handy in practice - as it's not always intuitive where to find a function that one searches)..

get the C# wrapper:
for A7.85.4 and A8.30.4, Version 2.3.9
