Question

I just generated a 32-bit dll from a library and am trying to use it with my windows based form application in C# (debug – x86). I added the dll file as a reference and now when I run the code I get the following error

System.IO.FileNotFoundException was unhandled
  Message=Could not load file or assembly 'org.apache.qpid.messaging.dll' or one of its dependencies. The specified module could not be found.
  Source=QpidRx_CSharp
  FileName=org.apache.qpid.messaging.dll
  FusionLog=""
  StackTrace:
       at QpidRx_CSharp.Program.Main()
       at System.AppDomain._nExecuteAssembly(RuntimeAssembly assembly, String[] args)
       at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args)

       at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
       at System.Threading.ThreadHelper.ThreadStart()
  InnerException: 

Any suggetsions on how I might resolve this issue ?

Answer 1

Have a look at the dll with the (free and excellent) ‘DependencyWalker’ to see what’s missing (since the error seems to indicate that’s the exact problem here: you are not fulfilling all needed dependencies).
