[Insight-users] AccessViolationException in ManagedITK

[Dan Mueller]

Hi Volodymyr,

I am having trouble reproducing the issue you reported.

I downloaded and installed Visual Studio C# 2010 Express (with .NET
4.0). Your program ran as expected without exception using the
pre-compiled ManagedITK assemblies built against ITK 3.20 x86
available at the Google Code page... (Though I did have to add an
app.config file with useLegacyV2RuntimeActivationPolicy=true to even
get the program to run).

What version of ManagedITK assemblies are you using? Pre-compiled
assemblies or did you compile them yourself? Perhaps it is a x64
issue...?

Cheers, Dan
