New Post: Exception System.Web.HttpContextWrapper is not marked as serializable

I am using Magick.NET-AnyCPU.dll 7.0.0.11 in an asp.net application using IIS 7.0. Any method call on MagickNET, such as "MagickNET.UseOpenCL = false;" generates an exception, which has as its innermost InnerException the following:

System.Runtime.Serialization.SerializationException: Type 'System.Web.HttpContextWrapper' in Assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable

The full stack trace is below.

I'd appreciate any thoughts why this exception is generated.
