WCF and out parameters

Question

It seems there is restriction in having the number of out parameters in WCF. My service reference only downloads one out parameter.

Example: if the service has the following method:

void methodA(out string param1, out string param2)

then the service reference will only create

methodA(out string param1).

Anyone knows how to solve this?

Answer 1

I don't believe there's a limit to the number of out-parameters.

However, for a method that returns void, the first out-parameter actually becomes the return value of the method in the service reference due to a limitation in WSDL. So I would expect the signature of the method to become string methodA(out string param2).
