Unable to get ImageMagick .Net working with Asp.Net 4.0 - image-processing

Question

I have downloaded the ImageMagick.Net source code from Codeplex and compiled using Visual Studio 2010. It builds but when I use the generated ImageMagickNET.dll into my Asp.Net 4.0 application I get the following error.
External component has thrown an exception.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Runtime.InteropServices.SEHException: External component has thrown an exception.

Has anyone got ImagMagick.Net working by compiling from the source code?

I know this is a bit of an old question, but this looks similar to an issue with unmatched ImageMagick versions that I was seeing.
If you are using the ImageMagickNET from their sources, you need to make sure you have ImageMagick 6.5.3-10 installed. This probably means building that release from sources, as I don't think the binaries are available anywhere (at least for Windows).
If you updated the ImageMagickNET project with sources from a new ImageMagick release, then you can use it with your newer installed version of ImageMagick. However, I experience several crashes when trying this approach with ImageMagick 6.6.6-10 on Windows. It may be that too much has changed in the underlying library for the ImageMagickNET wrapper to work correctly with this more recent version.
