Code Inspection: Merge conditional ?: expression into conditional access

Starting from C# 6.0, you can use the null-conditional operator (?.) to test for null before performing member access.

If you use the conditional ?: (ternary) operator for nullability check when accessing symbol's members, JetBrains Rider suggests replacing it with a more elegant ?. operator.

Here is an example of a quick-fix suggested by this inspection:

            
string GetAttr(XElement node, string attrName)
{
  var attrNode = node.Attribute(attrName);
  return attrNode == null ? null : attrNode.Value;
}

        

            
string GetAttr(XElement node, string attrName)
{
  var attrNode = node.Attribute(attrName);
  return attrNode?.Value;
}
