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

[James Perrins]

Thanks for that - I was looking for a setting like that but failed to find it.

However I'm not sure its the complete solution (as I've tried it and
still seem to have the same error) - the link you give states that you
need to still add:
[assembly: SecurityRules(SecurityRuleSet.Level1)] to your assembly to
revert to CLR2 transparency.

Unfortunately this
http://msdn.microsoft.com/en-us/library/dd409253(v=VS.100).aspx states
that even with the switch set - it doesn’t effect transparency rules -
which appears to be the breaking change :-(.  I'm assuming code
changes need to me made to mapscript_csharp rather than any of my code
consuming it.

If I was going to have a go at adding this into the mapscript_csharp
wrapper could you give me a pointer to where to look for the source -
I seem to have compiled it OK - but am having trouble seeing where the
source is amongst everything else.

Thanks again
James
