Code inspection: Local function is never used

This inspection reports a local function that is declared but never called and never assigned to a delegate. It mirrors the compiler warning for an unused local function.

Example

void M()
{
    void Helper()
    {
        Console.WriteLine("unused");
    }
}
            

void M()
{
}
            

Quick-fix

The quick-fix removes the unused local function.
