Dot Net Version Issue

[Anonymous]

hello guys,

i am trying some things with signatures and encryption... for this i want to create an object of the class

"System.Security.Cryptography.ECDsaCng"

so with a line

ECdsa = dotnetobject "System.Security.Cryptography.ECDsaCng"

i should recive the object...

but i always get " Runtime error: Cannot resolve type: System.Security.Cryptography.ECDsaCng"

so i think this could be because its not available in older versions than dot net 3.5...
i downloaded and installed 3.5 but still doesnt work. im working with xp 64, max 2009 64 bit. I have still installed older versions of dot net - so is there a way specifying some version to load or something??

thanks in advance,
stefan

Platforms

Windows 7, Windows Vista, Windows Server 2008 R2, Windows Server 2008

The .NET Framework and .NET Compact Framework do not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.

Possible cause?

thanks for your reply,

i tried on a vista ultimate x64 machine - its the same thing...

also on the detailed plattform support listed here: http://msdn.microsoft.com/en-us/library/bb882520.aspx

the xp64 is also listed as compatible.

the funny thing is - i coded the same test in c# on the same vista machine - and it works surprisingly - so the problem lies more in the maxscript-dotnet-connection than in the system...

other guesses?

Afraid not - I know nothing about .net - never touch it. I'll have to leave this one for someone who knows more about it.
