'!' requires its left operand to have a type parameter, class or interface type, but this operand has the type '<type>'

Dictionary member access, which uses an exclamation point (!) instead of a period (.), is valid only on a class or an interface.

Error ID: BC30103

To correct this error

• Replace the expression on the left of the exclamation point with one that evaluates to a defined class or interface type.
