Trying to get WebSharingAppDemo to load and work RRS feed

  • Question

  • Hi,

    I am relatively new to programming and have rather been thrown in the deep end. I have come across several things.

    Firstly, when I load the WebSharingAppDemo in either Visual C# or Visual WebDeveloper (both are 2008 Express editions), things seem to load okay except for the WebSyncContract project. I receive a message pop-up saying that the projec type is not supported. I can't seem to find out why this would be.

    Secondly, as I really have no idea about C#, is there a version of this app available in Visual Basic? I've converted as much as I am able, but not knowing the original language, some things look as though they should work, but obviously don't.

    Thirdly, (sorry, this is getting to be a lot to ask), when I look at the WebSyncContract.csproj, there seems to be an error






    WCFMetadata Include="Service References\" />




    I've looked everywhere I can think of, but can't seem to find a solution to this error. The error reads "The element "ItemGroup" in namespace http://schemas.microsoft.com/developer/msbuild/2003 has an invalid Child element in 'WCFMetaData' in namespace".

    Any assistance would be greatly appreciated.

  • looks like you dont have the WCF project template installed.

  • I agree with JuneT, you seem to be missing the WCF project template.

    The WebSharingAppDemo sample is only available in C#. We do not have the implementation in Visual Basic.

    The error you mention in the csproj is due to the missing WCF project template.

  • Thanks for the information. Now for the next REALLY stupid question...

    Where do I get the WCF Project Templates?


    Thanks again!

  • Okay, so I have finally got the WebSharingAppDemo-SqlProviderEndToEnd to compile and mostly work.

    The problem now is that when I try to open the program, I get a Named Pipes Provider error 40 error message (Can't open a connection to the server).

    I tried to do a named instance of my SQLEXPRESS (2008) server, but when re-compiling, it complains about the "\" in the server name (CAROL-PC\SQLEXPRESS).  I tried (as suggested somewhere) that I use CAROL-PC/SQLEXPRESS, but then the program can't find the server.

    At a loss.....again!!!!

  • would you mind posting the connection string and the error you get when using CAROL-PC\SQLEXPRESS?
    Thursday, July 29, 2010 2:30 PM
  • I've discovered the answer the problem with CAROL-PC\SQLEXPRESS. The compiler did not like the "\", so I have changed the string to @"CAROL-PC\SQLEXPRESS". The app builds and publishes just fine now.

    HOWEVER, when I run it and try to synchronise peer1 and peer2, I am now getting "Remote server returned an unexpected response (405): Method not allowed".

    I've checked the IIS server, and it seems to allow everything it's meant to.

    Floundering again.....

  • I am having a similar problem with deploying my WCF WebSyncContract service to IIS. It appears to be either a problem in my web.config or IIS settings. I have tried many many different things with no luck, any help would be greatly appreciated. I can provide trace logs if it would be helpful.


    Using Fiddler, I have found that "Remote server returned an unexpected response (405): Method not allowed" is referring to the POST method.

    <fieldset><legend>Most likely causes:</legend>
    • The request sent to the Web server used an HTTP verb that is not allowed by the module configured to handle the request.
    • A request was sent to the server that contained an invalid HTTP verb.
    • The request is for static content and contains an HTTP verb other than GET or HEAD.
    • A request was sent to a virtual directory using the HTTP verb POST and the default document is a static file that does not support HTTP verbs other than GET or HEAD.
    <fieldset><legend>Things you can try:</legend>
    • Verify the list of verbs enabled for the module handler this request was sent to, and ensure that this verb should be allowed for the Web site.
    • Check the IIS log file to see which verb is not allowed for the request.
    • Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests, click here.

  • can you check if you have WCF/IIS configured correctly?

     Refer to http://msdn.microsoft.com/en-us/library/aa751792.aspx section "Ensure That IIS and WCF Are Correctly Installed and Registered"
