Use the null-conditional operator instead of a ternary null check
Replace `x != null ? x.Y : null` with `x?.Y` — the null-conditional operator is shorter and expresses the same intent.

Bad example
Old codecsharp
| 1 | var v = node != null ? node.GetAttributeValue("x") : null; |
Explanation (EN)
The null-conditional operator expresses guarded access without repeating the receiver.

Notes (EN)
For a C# nullable receiver tested before one member access, check that the receiver is evaluated once and the resulting nullable type matches the surrounding assignment.
Exceptions / Tradeoffs (EN)
Do not apply this C# equivalence to JavaScript when null must remain distinct from undefined; check overloaded comparisons and side-effecting receivers.
