I have a class to generate test data that I have documented with a docstring.
```csharp
/// &lt;summary&gt;
/// In this scenario the user is new to the group, but may have existed from before.
/// &lt;/summary&gt;
class NewUserData {
    public User user;
    // More data fields here ...
    public NewUserData(){ 
        // Creating test data here ...
    }
}

var data = new NewUserData();

/// <inheritdoc cref="NewUserData"/>
var data = new NewUserData();
```"

Found out one can achieve this with the inheritdoc tag and specify the class name as cref.
```csharp
/// &lt;inheritdoc cref=&quot;NewUserData&quot;/&gt;
var data = new NewUserData();
