Code inspection: Multiple nullable attributes usage

tip

You can suppress this inspection to ignore specific issues, change its severity level to make the issues less or more noticeable, or disable it altogether.

NotNull and CanBeNull attributes can be used to indicate whether or not a parameter or a return value can be null. But consider the following code:

public void SetName([CanBeNull][NotNull]string name)
{
  myName = name;
}

Public Sub SetName(<CanBeNull> <NotNull> name As String)
    myName = name
End Sub

This annotation does not make much sense since the two assertions contradict each other.
