FX COP Could not resolve type reference: System.Windows.Input.ICommand

Question

Having troubles with FXCOP on our buildagent ONLY and only through the command line tool ONLY.

I am using the Caliburn.Mirco framework and added a custom trigger so i can use the delete button. this class implements the ICommand interface

the error is : "The following error was encountered while reading module 'MyProject.UI': Could not resolve type reference: [System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]System.Windows.Input.ICommand"

Answer 1

Have you tried passing /gac as an option? There is also /directory to tell FxCop to load any required assemblies from that folder(s).

There are many more options available.
