When you generate a class out of a schema with an element configured to allow mixed content (child attributes and elements as well as text), you should expect the corresponding generated field type to be a string array;
So – if you have a schema that looks like this
<?xml version=”1.0″ encoding=”utf-8″?>
<xs:schema targetNamespace=”http://tempuri.org/XMLSchema.xsd” elementFormDefault=”qualified” xmlns=”http://tempuri.org/XMLSchema.xsd” xmlns:mstns=”http://tempuri.org/XMLSchema.xsd”
xmlns:xs=”http://www.w3.org/2001/XMLSchema”>
<xs:element name=”SomeElement”>
<xs:complexType mixed=”true”>
<xs:sequence>
<xs:element name=”Child1″ type=”xs:string”/>
<xs:element name=”Child2″ type=”xs:string”/>
<xs:element name=”Child3″ type=”xs:string”/>
</xs:sequence>
<xs:attribute name=”SomeAttribute” type=”xs:string”/>
</xs:complexType>
</xs:element>
</xs:schema>
(not ’SomeElement’ being a complex type allowing mixed content)
The fields in the generated class would look like
public partial class SomeElement {
private string child1Field;
private string child2Field;
private string child3Field;
private string[] textField;
private string someAttributeField;
.
.
.
The reason is that an XML corresponding to the schema might look like this –
<SomeElement xmlns="http://tempuri.org/XMLSchema.xsd" SomeAttribute="someAttributeValue">
Some free text
<Child1>Child1 text</Child1>
Some more free text
<Child2>Child2 text</Child2>
yet some more free text
<Child3>Child3 text</Child3>
</SomeElement>
And so by using a string array to hold the text the deserialiser can keep string portion separately.
Initially, I thought, this allows the structure to represent the original xml accurately, but this is not exactly the case – you would still not know for certain where each string portion existed, especially if in the source XML you get a few elements that don’t have text between them, which , I suspect, is why when I serialise the instance back to xml I actually get –
<?xml version="1.0"?>
<SomeElement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" SomeAttribute="someAttributeValue" xmlns="http://tempuri.org/XMLSchema.xsd">
<Child1>Child1 text</Child1>
<Child2>Child2 text</Child2>
<Child3>Child3 text</Child3>
Some free text
Some more free text
yet some more free text
</SomeElement>
Now, I don’t particularly like this sort of xml, and shy away from mixed content; I don’t believe that xml snippets like my samples above are useful, specifically I don’t think that mixing elements and text is particularly nice.
However, consider an element with an attribute and some text – the following is quite reasonable I think, and yet requires mixed content –
<Phone type=”mobile”>some text here</Phone>

I just installed Microsoft Enterprise Service Bus Guidance framework (November 2007 version for BizTalk 2006 R2). Although lengthy installation process is well documented in the accompanying help file I ran into multiple issues and it took a couple of days to sort everything out.I’d like to mention here majorproblems/solutions in case somebody decides to go through the same.First, if you install on other than default location (C:/%PROGRAM_FILES% and C:/Projects)make sureto update all scripts and command files as well as bindings.Second, I had issue withUDDI service configuration. It wouldn’t install until I enabled NTLM authentication for IIS.It is done by executing IIS utility scriptper this MS article. But thiscommand workedonly when I dropped quotes around Negotiate,NTLM contrary to MS KB article. Also,make sure the default web site ID is “1”. Some of my computers had it set to different numbers so I had to change command line appropriately. In the end command that worked looks like this:
cscript adsutil.vbs get w3svc/<Default Web Site ID>/root/NTAuthenticationProviders Negotiate,NTLM
Anotherproblem is that assemblies in MSI packagesare signed with different key comparing to source projects. So even if you install all ESB componentsfrom source you will run into this issue because some of the projects reference assemblies from packaged installation. Solution is to go through all project references, remove them and add new to ones generated from source code. The same applies to sample applications. Don’t install them from MSI if you chose source code based ESB installation. Open project, update references, rebuild and deploy.

This year the usual TechDays event focused exclusivelly on Dev contents, and reduced to two days. I was help at IST’s campus on Tagus, a smaller but also cosier space. I did three sessions, all of them on the ARChitecture track:
ARC206 Patterns & Anti-Patterns. I did this session together with Tiago Pascoal, and we mostly talked about Architectural Anti-Patterns (and not Patterns/Design Patterns), in a Developer-oriented session. The original TechEd EMEA 2008 session we based it off was one of the best I’ve seen yet, at and I think we managed to surpass the original delivery and contents with examples and real-life experiences. We had very good feedback on this session.
ARC208 O que h%u00e1 de novo no BizTalk 2009. I do one of these every two years :-). It’s a difficult session to do, because the next release of BizTalk Server has mostly small incremental features, and because there are lots of them. I did two demos, of the developer experience and the new Sql Adapter, to break the sequence of slides, and also mentioned the ESB Guidance 2.0, the relationship with Dublin, and the ISV Royalties program.
ARC209 Windows Azure – Introdu%u00e7%u00e3o aos .Net Services. This session was similar to my presentation last year on this same topic (when it was still called “BizTalk Services”), but with more deep technical content and demos. The main host of the session was Pedro F%u00e9lix, I mostly did the connection to real-life use cases, some clarifications, and the final segment on hosted Workflow, the third component (with the Access Control and Service Bus) of .Net Services. This session had a very high rating.
All the presentations are available here for download in PDF format at my Skydrive.

I noticed a new tooltip yesterday in the BizTalk Admin Console when a message had failed in the Receive Pipeline because of unexpected characters in the message (and because no encoding had been set in the Xml declaration). Interesting to see that the message body text view recognises that […]

What a week it has been folks – I left Sydney in 30C degrees with sun, sand and beaches…..I
thought “How cold can it be?” (you never really get that appreciation till you hit
the ground)>
Cold….very cold!!! Now I’ve been skiing many times, but this was just something
else.
It caused Beijing to be blanketed in snow and very beautiful – What a fantastic place!!!
Definitely a come back place – just nothing like what I expected.
The people so friendly, helpful and always with purpose in their eyes. The food is
some of the freshest I’ve eaten and such healthy diets (steamed cabbage, mushrooms
etc etc) – nothing like the ‘Western Chinese Resturants’ back home 🙂
On to the reason why I was there – Training
I had approx 50 students coming to hear my Chinese English (which I must say is much
better than me listening to them speaking Mandarin) and we covered in-depth BizTalk
2009 agenda
We covered some great material looking into Governance and ESB 2.0 due to hit around
the same time as BTS2009 (June-ish I believe, earlier I’m told)
We actually communicated quite well – I played many games and brought over a bunch
of Aussie gifts for them (which consequently we found out were made in China!)
The usual areas of BizTalk were little used previous by students – SSO, Rule
and BAM. For so little effort there’s so much mileage in these guys.
Training Results
For the training the average mark I received was 8.5/10 across nearly 50 students,
which for my first time in China I was very happy with. The most important thing for
me though is not the marks, but what the students walk away having learnt!
Not all work Play Time
As luck would have it I had an extra day to play on my trip this time – so in negative
degree temps I went to the Center of Beijing and put on my tourist hat and went to
the Forbidden City (& surrounds).
Lastly I learnt many things from my students this week with
1. KFC is a ‘top class’ resturant in Beijing
2. Starbucks is a ‘romantic’ place (where couples go for dates)
If we were on Mythbusters right now……. compared to Sydney – these are Busted!

I received an unusual phone call from a co-worker today: he wanted to find out the product key of BizTalk Server 2006 installed on a server (I didn’t go as far as asking why – lost disk probably).
After a few minutes this is where I got to: open regedit and browse to:
HKLM\SOFTWARE\Microsoft\BizTalk Server\3.0\Registration\DigitalProductID
Now download something […]

The BizTalk Adapter Pack Migration Tool is a utility that helps developers migrate BizTalk projects using the BizTalk 2006 SQL or the BizTalk Adapter v2.0 for mySAP Business Suite to their corresponding WCF-based versions from BizTalk Adapter Pack v2!
With the help of this utility you will be able to compile and deploy your application within minutes. Some of the highlights for the Migration Tool are:
Works on the source project files
Generates equivalent schema definitions for the operations used in the existing project
Generates new maps to convert messages from older formats to the new format
Modifies any existing maps to work with the new schemas
A new project is created upon completion, which uses the SQL and/or SAP adapters from the BizTalk Adapter Pack v2
The tool works for most common scenarios of maps and orchestrations, however it is only meant to be a starting step towards migration to BAP and we are open to receiving feedback to add scenarios,.
