wcf 由于内部错误，服务器无法处理请求

Question

I have created some wcfs. One of them when i have tried to run it produced the picture below

When i have created the config and cs files and tried to run it with the code mentioned in the picture above after i have edited the web.config file of the web form from where it would be called the following comes up:

At this point, i read in similar posts about microsoft service trace viewer and svclog files. But since i am pretty new at this no helpful info could come out from the files. Any help would be really appreciated

I think that posting here all the text would be a bit too big, though i can upload the photo in a cloud. I have changed a bit the name of the web service as its functions the error though remains the same.

<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_Icheck_product" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:51182/check_product.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_Icheck_product"
                contract="Icheck_product" name="BasicHttpBinding_Icheck_product" />
        </client>
    </system.serviceModel>
</configuration>

The above is the output.config and the one below is the web.config after i added data from the above:

Answer 1

I had the same error in a service I created. What I did was change this line in the web.config file: serviceDebug includeExceptionDetailInFaults="false" to "true" It gives a lot better detail explanation, in my case it was a typo in my connection string
