I made a test function with WCF and developed it by updating the reference in the client

1. Service- test(string a) , Client- test(string a)

The service then modified the parameter for this function and debugged it, but it worked fine
2. service – test(string a, int b, int c) , Client- test(string a) (Still no reference update)

So I did one more test, and the service made overloading with different parameters
3. service – test(string a, int b, int c) , Client- test(string a) (Still no reference update)
service – test(string a, string b string c),

of couse In case 3, it didn’t work.

Finally, I wonder why number 2 worked

I want to know how it works when there is one function and when there are two functions(Overloading).
