XmlValidationStep:  It is the equivelent to using SelectSingleNode and must resolve to a node set

XmlValidationStepEx:  It utilizes XPathNavigator.  XmlValidationStepEx should be used when evaluating against functions such as Count()

I am sad to say that as I write this, the information is already irrelavant, however I feel it should be written simply because it is a problem nonetheless.

The circumstances (long story, will post about it later) around the BizTalk 2009 project I’m working on is forcing us to, most than likely use SOAP adapter instead of WCF — In case you are not aware, the SOAP adapter has been tagged as deprecated in BizTalk 2009 and should not be used with new development.  Nevertheless, it is what it is, we have to make do with the problem at hand.

The SOAP adapter need a proxy generated from a WSDL.  In order for the entities to be made available to an Orchestration or Map during design time, the Web Reference must be added to a BizTalk project.  This is where the pain began….the WSDLs we are seeing are north of 800KB (i.e. REALLY big WSDL).  That by itself is not a problem, however when the generated entities are used in a BizTalk map, Visual Studio 2008 SP1 will spin for 10 – 20 minutes and try to consume every bit of RAM available before throwing a very frustruction System.OutOfMemoryException.  Don’t understand it, and absolutely can’t work around it.

To see for yourself:

1. Create a BizTalk project
2. Add Web Reference to a large (> 500kb) WSDL
3. Create a Map and transform anything into an entity created during step #2.
4. Hit build and enjoy the show

For the record, my development environment consists of Windows 2003 Enterprise x64 with 3.75GB of RAM.

I know what you are thinking, may be we should pare down the WSDL.  Well, let just say the 3rd party vendor can’t do that.  I will update if/when I find a workaround.

Update 09/14/2009:  One of my colleague figured this out.  The root of the problem is a bunch of circular reference in the schema — Entity A contain Entity B, B contain Entity C, C contain A.  This is a known deficiency in the .NET XMLSerializer.

Update 09/18/2009:  A bunch of test later, it looks like WSDL size is a problem at design time (i.e. can’t compile) and circular reference is a problem at run time (i.e. SOAP Adapter can’t serialize the message using XMLSerializer).

I kept getting this error in my Vista Enterprise install.  I tried a bunch of stuff including turning off the firewall, going to a different network, and at the end of it all, the error had nothing to do with “Timeout” — The product key I’ve entered was bad.  Arrgh!

This particular client appear to programmatically connect to the BizTalk server via Telnet as a way to keep the socket open.  In return, BizTalk would treat the connection as having a missing body (not to be confused with an empty body). To solve the problem, although it’s not ideal, is to put a try/catch around the GetOriginalDataStream() and return null if it encounters an error.   Unfortunately, the side affect of this is an active blank message instance in the BizTalk Administration Console.  But at least there are no more error event logs and suspended message instances.  

public IBaseMessage Execute(IPipelineContext pContext, IBaseMessage pInMsg)
{
    IBaseMessagePart msgBody = pInMsg.BodyPart;

if (msgBody != null)
{

string oldStr = string.Empty;

try
{
    using (StreamReader sr = new StreamReader(msgBody.GetOriginalDataStream()))
    {
         oldStr = sr.ReadToEnd();
    }
}
catch
{
    return null;
}

Error:
There is no build provider registered for the extension ‘.svc’. You can register one in the <compilation><buildProviders> section in machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value ‘Web’ or ‘All’.

Solution:

<compilation>
     <buildProviders>
          <add extension=".svc" type="System.ServiceModel.Activation.ServiceBuildProvider, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

Error:
This collection already contains an address with scheme http.  There can be at most one address per scheme in this collection.

Solution:

      <serviceHostingEnvironment>
      <baseAddressPrefixFilters>
           <add prefix="http://services.edoverip.com/" />

Error:
The WSHttpBinding with name WSHttpBinding failed validation because it contains a BindingElement with type System.ServiceModel.Channels.SymmetricSecurityBindingElement which is not supported in partial trust. Consider disabling the message security and reliable session options, using BasicHttpBinding, or hosting your application in a full-trust environment.

Solution:
This one is a bit tricky.  If you prefer to use wsHttpBinding, you will have to set the Security Mode to either None or Transport.  For example,  to set it to None, it looks something like this…

<bindings>
   <wsHttpBinding>
        <binding name="wsHttp">
            <security mode="None" />
        </binding>
   </wsHttpBinding>
</bindings>

<services>
     <service behaviorConfiguration="DistanceWS.ServiceBehavior" name="DistanceWS.Service">
          <endpoint binding="wsHttpBinding" bindingConfiguration="wsHttp" contract="DistanceWS.IService" />
          <host>
               <baseAddresses>
                    <add baseAddress="http://localhost:8731/Design_Time_Addresses/DistanceWS/Service/" />
               </baseAddresses>
          </host>
     </service>
</services>

That’s all I can think of for now. I will update this post if I come across anything else. Meanwhile, enjoy and good luck!

- Domain: $14.99/yr
- Private Domain Registration: $8.99/yr
- Email: $19.99/yr (which reduces your domain to just $1.99)

Total: $30.99/yr

The tricky part (while not really tricky at all) is configuring thr DNS of the Google App to point web hosting to the 3rd party while retaining email and everything else on Google.

To configure DNS for your Google App to work with a 3rd party web host:

1. Go to the admin dashboard for your domain
2. Click Domain Settings in the top navigation bar
3. Click the Domain Names tab under Domain Settings
4. Click Advanced DNS Settings and following the instructions on the next page
5. Once you’re logged in, click on your domain name
6. Click “Total DNS Control and MX Records” in the middle column of the top box
7. Once you’re in Total DNS Control, remove all the A Records and put in a single A record with @ as the host and IP pointing to your 3rd party web host.
8. In CNAMES, modify the www record from being pointed to ghs.google.com to @.

That’s it! The changes might take up to 48 hours to propagate but your job is done.
