wcf service and web page in single project

 

In practical, these two should be separated. From my experience, most of the business logics are coded as a WCF services. So that it will be consumed by any web applications including ASP.Net. Also, WCF provides more deployment options than the normal ASP.Net web application. So if you implement the WCF as a separate project, you can take this advantage also. If you implement WCF in single project, you missed out these features.

 

how can i maitain a wcf service and web page thats include wcf service in a single project 

 

As  i told before this is not advisable. If you are doing some home work project means you can go with it. There are few ways are there:

1) You can include the "Class Library" project and add an .svc file then implement it. 

2) Otherwise, you can include the SVC file in the project itself. 

 

In both cases, VS will create the interface file for you, where you have declare the contracts and implement it in SVC file. 

 

Hope this helps!
