Hi...
Thanks a lot......
I still have few queries...
1. I made a sample method - public int add(int i, int j) {return (i+j);}
When I call this method in aspx.cs file, I get two methods - add(int i,int j) and addasync(int i,int j)
what is the difference between these two methods and which one to use.
2. I have deleted the Interface (IService.cs) file from my portal and made all methods in class file (Service.cs).
Is this acceptable ?
3. End Point -
In wcf service portal, my webconfig file is -
-------
My Query is-
Localhost now runs perfectly..
But, once I publish the website and host in server (other machine - 1.1.1.1), then endpoint issue arises.
I want a solution such that -
1. endpoint address must be a specific URL
2. No need to change it on repeated basis. Once fixed in webconfig file, it must work everywhere.
I tried the following -
-------
but none worked...
Please guide

Hi,    If  server name is same but service name is different then we can use as common part as a base address but here one is localhost and one is specific server There is a way when we are handling with multiple endpoint for localhost or specific server. Please refer this link this will be helpful.   https://debugmode.net/2014/06/10/dealing-multiple-endpoints-of-a-wcf-service/   let me know if you face issues

Hi.. For 3rd point -
While I run the application on my localhost, the endpoint address is -
http://localhost:21345/MyWCFService.svc
-------
When I deploy this in other server , I need to change the endpoint address.
New server on which my application is deployed is - 12.11.14.15
-----
Can we have a common endpoint so we do need to change is on repeated basis ??

Hi,

1-Normally we are using add(int i, int j) {return (i+j);} method

For Async method please refer this link this will provide whole idea when we are using this

2-

Yes In place of Interface file you can use CS file also.

3-

Need to host WCF service also in server.and give that path as end point address.

like example where XX.XXX.XXX.X is server IP address where service is hosted.

binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_Service1" contract="ServiceReference1.Service1"

name="BasicHttpBinding_Service1" />

Let me know if you face issues.
