Hi,
Thanks again for helping. This is what I did:
I just took your dll. Then dropped it to the web app's bin folder.
Then if I try to open existing pages which has no code of ImageMagickNET dll gives the exception I mentioned earlier.

Same error appears if I add a refenerce to the dll in bin folder.

Since it breaks adding the dll the bin folder, I can't test the code at all.
Is there anything I missed? Or anyother file needed to be installed or some permission needed to be given?

I searched Google and found that we get similar exception when we try to use a Native dll (written in C++ say) in C# asp.net app

Is this a native dll or it is a .NET dll. Since it is a wrapper, it must use ImageMagick dll written in C++ behind the scene. Not?

How do I use this dll in asp.net app?

Thanks a lot for working on this
Have a great day.
