c# - Use multiple contracts but single proxy -


i've created few contracts:

[servicecontract] public interface iinterface1 {     [operationcontract]     void method1(); }

and

[servicecontract] public interface iinterface2 {     [operationcontract]     void method2(); }

created class implementation.cs inherits them both , implements interfaces. created few endpoints every contract, different operations worked on different protocols:

   <service name="implementation">     <endpoint binding="netnamedpipebinding" contract="iinterface1" />     <endpoint binding="nettcpbinding" contract="iinterface2" />

i want clients, discover service, use 1 proxy instead of two. possible them export single proxy somehow, expose both contracts?

as tim had said abc of endpoint -- address, binding , contract.

you can have 1 proxy per class, concept, design , implementation of wcf. otherwise, client programmers (users) confused, , might scratch heads.

technically can have multiple contracts single proxy, however, have build scratch @ client side, , not use wcf.

when using wcf @ client side, either generating proxy classes through svcutil.exe or handcrafting, use system.servicemodel.clientbase base class of proxy class. since clientbase takes 1 contract, have 1 proxy class per contract.

for 1 contract, may publish multiple endpoints.

in config above, have declared 2 endpoints 2 contracts in different bindings. client see 2 contracts generate 2 proxy classes.

if have following config

<service name="implementation">     <endpoint binding="netnamedpipebinding" contract="iinterface1" />     <endpoint binding="nettcpbinding" contract="iinterface2" />     <endpoint binding="simplehttpbinding" contract="iinterface1" />     <endpoint binding="simplehttpbinding" contract="iinterface2" /> </service>

the client still generate 2 proxy classes, not 4, not 1. since clients care contracts, not implementation.

proxy classes have no knowledge of bindings. binding use determined in client codes or client config.

contracts, implementation, endpoints, binding, address , client proxy separated concerns of different parties, don't mix them.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
