c# - LoadLibrary call from MVC application running in IIS -

I have a problem executing this line of code in my MVC application:

 
 Code> IntPtr HModule = Load Library (Bondprovy settings. AssessmentFilePath);   
 The problem is that  hModule  is always  0 .  
 If I run the same code with the same value for  BondProbeSettings.AssemblyFilePath , but instead of MVC app  hModule  instead of a console application, non-zero  
 Should I consider any security issue?  
 The signature for the load Libre is:  
  [DllImport ("kernel32.dll", chartset = CharSet.Auto)] Static extern IntPtr LoadLibrary (string lpFileName);    
 
 
 Change the announcement to:  
  [DllImport ("Kernel32.dll", Charset = Charset Auto), SetLastError = true)] Static Extern IntPtr LoadLibrary (string lpFileName);   
 And your code:  
  IntPtr hModule = LoadLibrary (BondProbeSettings.AssemblyFilePath); Throw new system (hModule == IntPtr.Zero). ComponentModel.Win32Exception ();   
 Now you will know why it does not work.
