Why does my library built with Application Compiler crash due to undefined function 'pathdef'?

I am building a .Net class library dll which wraps some Matlab functions in .m files. The build completes and the .dll is produced. I can reference the DLL in a .Net project, but when the project runs, I see these errors in the debugger:

 %
  'Example1.exe' (CLR v4.0.30319: Example1.exe):
  Loaded 'C:\Windows\Microsoft.Net\assembly\GAC_MSIL\MWArray\v4.0_2.17.1.0__e1d84a0da19db86f\MWArray.dll'.
  Undefined function or variable 'pathdef'.
  Error in startup (line 1)
  Exception thrown: 'System.ApplicationException' in MWArray.dll
  Exception thrown: 'System.Exception' in MWArray.dll

and the class doesn't load. My scripts do not call pathdef. What is wrong?

Hi Morris,

Try executing the following commands from MATLAB command prompt,

restoredefaultpath % This will remove any custom paths
rehash toolboxcache
savepath
