[mapserver-users] Re: Mapscript c# VS 2010 framework 4 and memory leaks

[James Perrins]

Hi Tamas,

Thanks for that - and for all your efforts maintaining these.
I'm a bit up against it needing the 32 bit version for VS 2010 for
some demos.  I grabbed the source, and complied it in VS 2010 (just
changing the makefile so that it recognised 10.x as a valid platform)

Things seemed to compile - but when I call something like
mapObj(MyMapFile) I get an error about

"Attempt by security transparent method
'OSGeo.MapServer.mapObj..ctor(System.String)' to call native code
through method 'OSGeo.MapServer.mapscriptPINVOKE.new_mapObj(System.String)'
failed.  Methods must be security critical or security safe-critical
to call native code."

Is this because there is more stringent security with Framework 4, or
has my compilation not been as successful as I hoped.
Do you know of a quick fix to get me over this until you get a chance
to build the new libraries (e.g. making it full trust or something)?

Many Thanks
James
