It's a Func with one generic parameter, which defines the return type It has no parameters If you want to add them... add them

Put some generic parameters before the one you already did yeah Last one is the return type

thank you all. I didn't know you have to put the parameter name between the 2 brackets

btw is there any way to also pass a value to the parameter like that?

I think you will need to type it (int foo = 0) => { ... } And at that point might as well use a var

var func = string (int foo = 0) => $"Number is {foo}";

var func = string (int foo = 0) => $"Number is {foo}";

I think it's a fairly new addition to the language, though

You can specify return types for anonymous lambdas?
