WCF web service error: The service cannot be activated because it does not support ASP.NET compatibility

I am trying to create a restful wcf web service. When I try to connect to the service through the client I get the following error:

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'.

Others have had problems, but they fixed it through changes to their web.config. I have implemented their fix, but still the problem exists. here is my web.config:

<behavior name="WebBehavior" >
<webHttp />
<behavior name="MyServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
<behavior name="">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
<service behaviorConfiguration="MyServiceBehavior" name="myfirstwcf">
<endpoint address="ws" binding="basicHttpBinding"
contract="Imyfirstwcf" />
<endpoint address="ws2" binding="wsHttpBinding"
contract="Imyfirstwcf" />
<endpoint address="" behaviorConfiguration="WebBehavior"
contract="Imyfirstwcf" />
<endpoint address="mex" binding="mexHttpBinding"
contract="IMetadataExchange" />
<serviceHostingEnvironment aspNetCompatibilityEnabled= "true"
multipleSiteBindingsEnabled="true" />

On your main service you could mark your service as:

        RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
