Code Analyzer for C#

There is a newer version: 10.2.0.105762

Why is this an issue?
Exceptions types should provide the following constructors:

   public MyException() 
   public MyException(string) 
   public MyException(string, Exception) 

The absence of these constructors can complicate exception handling and limit the information that can be provided when an exception is thrown.
How to fix it
Code examples
Noncompliant code example
public class MyException : Exception // Noncompliant: several constructors are missing
{
    public MyException()
    {
    }
}

Compliant solution
public class MyException : Exception
{
    public MyException()
    {
    }

    public MyException(string message)
        : base(message)
    {
    }

    public MyException(string message, Exception innerException)
        : base(message, innerException)
    {
    }
}
