A local variable is assigned a value, but the variable is never read. This suggests that the local variable is either useless and should be removed, or that the value was intended to be used somewhere.

Ensure that you check the control and data flow in the method carefully. If a value is really not needed, consider removing the variable. Be careful, though: if the right-hand side has a side-effect (like performing a method call), it is important to keep this to preserve the overall behavior.
