There was no need to give the function a name, such as: basicParabola (x) = x2 In this sense, lambda functions are unnamed and anonymous. Lambda functions in Java This discussion on the etymology of lambda functions is interesting, but the real question is...
This can be a lambda expression: C# Copy storedProcedureBuilder.HasParameter(a => a.Name); Or a string, which is particularly useful when mapping shadow properties: C# Copy storedProcedureBuilder.HasParameter("Name"); Parameters are, by default, configured for "input". "Output" or "...
