The type ‘RestService.weddingservice’, provided as the Service attribute value in the ServiceHost directive could not be found

Im trying to create my first WCF restful service.
In VS2010 I open weddingservice.svc and then hit F5. A browser opens to http://localhost:50043/weddingservice.svc
But there, this is the error I get:

Server Error in '/' Application.

The type 'RestService.weddingservice', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.

Below my code, I hope anyone is able to see what Im doing wrong. Am I not using the correct URI? What did I miss?

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

Set the

<serviceDebug includeExceptionDetailInFaults="false" />

to

<serviceDebug includeExceptionDetailInFaults="true" />

in order to get more details

and try to run the process again

Method 2

I reconfigured my project recently and ran into this error.

It was a setup error, my service DLLs weren’t being placed in the right directory when publishing the website.

Method 3

Please change your service element from:

<service name="weddingservice">

to :

<service name="RestService.weddingservice">

That should resolve your problem

Method 4

My Problem was resolved when i added the Bin folder and obj folder into the folder path manually. I am able to access it perfectly now.

Method 5

I had the same issue. Simply deleting the bin and obj folders and rebuilding fixed the issue.

Method 6

My project had the dlls being built to a folder under the bin directory to match the configuration name, so if the project name was DemoWCF and the configuration was Debug the dll would be here:

/bin/Debug/DemoWCF.dll

When I removed the Debug/ from the output path and built the dll to here:

/bin/DemoWCF.dll

everything launched as expected.

This was configured under the Build tab on the project properties in the Output path
