Compiler Error CS0748

Inconsistent lambda parameter usage; parameter types must be all explicit or all implicit.

If a lambda expression has multiple input parameters, some parameters cannot use implicit typing while others use explicit typing.

To correct this error, either omit all parameter type declarations or explicitly specify the type of all parameters.


The following code generates CS0748, because, in the lambda expression, only alpha is given an explicit type:

class CS0748  
    System.Func<int, int, int> d = (int alpha, beta) => beta / alpha;
