I am running a 32 bit application on an IIS 7 server in classic mode. I need to have *.svc mapped to ISAPI.dll.

I have been working off of Microsoft's site to get as far as I have gotten.

I have been following my errors up to now but now I get a 500.19 error I do not understand.  In the error page under config source I get this

-1:
 0:

Here is the portion of the web.config file I have been working on:

<system.web>
<httpHandlers>
      <add verb="*" path="*.svc"
        type="SVCAspHandler, SVCAspHandlerAssembly" />
      <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" validate="false" />
    </httpHandlers>
        <authorization>
            <allow users="etariffdev\TMSService" />
        </authorization>
  </system.web>
  <!--
        The system.webServer section is required for running ASP.NET AJAX under Internet
        Information Services 7.0.  It is not necessary for previous version of IIS.
    -->
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
        <caching enabled="false" />
        <directoryBrowse enabled="true" />
      <add name="SVCAspHandler" path="*.svc" verb="*"
        Modules="IsapiModule"
        scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\inetsrv\isapi.dll" />
  </system.webServer>

Can anyone help me get this working?

I think I am missing a statement here:

<add verb="*" path="*.svc" type="SVCAspHandler, SVCAspHandlerAssembly" />

I've traced it down to this:


ModuleName           IsapiModule

Notification      128

HttpStatus       500

HttpReason      Internal Server Error

HttpSubStatus     0

ErrorCode     0

ConfigExceptionInfo

Notification          EXECUTE_REQUEST_HANDLER
 
I suppose this means a problem with the Isapi module. Any ideas on how to find out what the problem is?

Could this be correct or be the problem?

<handlers accessPolicy="Read, Execute, Script">
            <remove name="ISAPI-dll" />
            <add name="ISAPI-dll" path="*.dll" verb="*" type="" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="File" requireAccess="Execute" allowPathInfo="true" preCondition="bitness32" responseBufferLimit="4194304" />
            <add name="svc-ModuleMapping" path="*.svc" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" preCondition="classicMode,runtimeVersionv4.0,bitness32" />
            <add name="ASP.NET-ISAPI-4.0-Wildcard" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv4.0,bitness32" />
        </handlers>

Was not a mapping problem at all. It was permissions. I had to go into Management - IIS Management permissions and allow asp.net.
