I got the following error when I was trying to host my WCF service in IIS 7.5 using WsHttpBinding

The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as ‘Allowed’ or ‘Required’.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as ‘Allowed’ or ‘Required’.

Solution:

One of the  solution is to turn-off ASPNet compatibility in service configuration file

<serviceHostingEnvironment aspNetCompatibilityEnabled="false"/>. It worked for me.

I got this error when I tried to host the WCF service in the IIS 7.5 using WSHttpBinding.

Exception
[System.ServiceModel.Security.SecurityNegotiationException] {"SOAP security negotiation with ‘http://localhost/Migraton/MigrationService.svc&#8217; for target ‘http://localhost/OrderService/OrderService.svc&#8217; failed. See inner exception for more details."}

Inner Exception
[System.ComponentModel.Win32Exception] {"The Security Support Provider Interface (SSPI) negotiation failed."}

Solution

The solution was to change the following userPrincipalName in the <userPrincipalName value="MACHINENAMEASPNET" /> to <servicePrincipalName value="host/localhost" /> . This did the trick and solved the issue.
