C＃项目没有实现WCF的更新

Question

I have a WCF webservice and another c# project. I added the WCF webservice to my project to do some processes. But I changed a function's return type in webservice, then tried to update the webservice from the project, it still sees the old return type.

I deleted the webservice reference from my project and re-added back into the project, it still sees the old return type. Where does it cache these information?

Answer 1

If you are running through IIS, sometimes this can hold onto the dll.

Here is everything i can think of that I'd try

1. Backup
2. Delete bin/obj folders in both projects
3. Restart IIS
4. Rebuild WCF project
5. Client project - Right click on the reference -> "Update References" and rebuild client project (possibly do the delete and re-add as you have done).
6. On a couple of occasions (in older versions), I've even had to close and re-open VS.

That can be a really frustrating issue on the odd occasion you hit it. HTH.

Answer 2

检查Web服务URL的Web.Config条目。

Answer 3

When you remove the service and add it again those downloaded classes to your system should be deleted however if for some reason you recon they are there then do the following check: Now go to the service reference folder and expand it. All the necessary classes and definition for constructing the proxy reside in the following folder: ...\\Service References...

You can check whether this folder gets emptied. When you re-add them you can check the reference file yourself to see whether new definitions are available.
