Could not load file or assembly or one of its dependencies. The system cannot find the file specified.

Assembly Load and loading the “sub-modules” dependencies.

Description:

My application dynamically loads assemblies at runtime from specific subfolders. These assemblies are compiled with dependencies to other assemblies.


Exception:

Could not load file or assembly 'DiagnosticTask, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.


Resolve:

• When dependencies assemblies are created in definied folder: ex. \plugins use:
  <probing> Element - Specifies application base subdirectories for the common language runtime to search when loading assemblies.

• Find the dll file and copy it over to the bin directory.
  
•  Add Reference on your root web projec. Make it bin deployable by setting Copy Local to true
