Code Analyzer for C#

There is a newer version: 10.2.0.105762

Why is this an issue?
This rule applies whenever an if statement is followed by one or more else if statements; the final else if
should be followed by an else statement.
The requirement for a final else statement is defensive programming.
The else statement should either take appropriate action or contain a suitable comment as to why no action is taken. This is
consistent with the requirement to have a final default clause in a switch statement.
Noncompliant code example
if (x == 0)
{
    DoSomething();
}
else if (x == 1)
{
    DoSomethingElse();
}

Compliant solution
if (x == 0)
{
    DoSomething();
}
else if (x == 1)
{
    DoSomethingElse();
}
else
{
    throw new InvalidOperationException();
}

Exceptions
