Properties with only setters are confusing and counterintuitive. Instead, a property getter should be added if possible, or the property should be replaced with a setter method.

Noncompliant Code Example

class Program
{
    public int Foo  //Non-Compliant
    {
        set
        {
            // ... some code ...
        }
    }
}

Compliant Solution

class Program
{
    private int foo;

    public void SetFoo(int value)
    {
        // ... some code ...
        foo = value;
    }
}

or

class Program
{
  public int Foo { get; set; } // Compliant
}
