I am able to build the program but when I run the program from the command line I get an error message. The error message is "The type or namespace name 'Microsoft' could not be found (are you missing a using directive or an assembly reference?)". I am using the command line to run the program because I am trying to compare two assemblies that are in different directories. I am not sure how to fix this error message.

The code I am using is below:19I am new to C# and I am trying to write a program that will compare two assemblies and return true if the assemblies are the same and false if they are different. I am trying to use Microsoft.Coyote.Rewriting.AssemblyDiffingPass class to compare the assemblies. I am able to build the program but when I run the program from the command line I get an error message. The error message is "The type or namespace name 'Microsoft' could not be found (are you missing a using directive or an assembly reference?)". I am using the command line to run the program because I am trying to compare two assemblies that are in different directories. I am not sure how to fix this error message. I am using Visual Studio 2019. The code I am using is below:20using Microsoft.Coyote.Rewriting;21using System;22using System.Collections.Generic;23using System.Linq;24using System.Text;25using System.Threading.Tasks;
