Failed while creating a [orchestration type] service

This is more of a note to self, every time I see this one (it’s quite rare), I’m kinda wondering where I’ve seen it before.
I was running some tests, after having made a few changes to an orchestration, and to my surprise I found this error (source: XLANGs) in the eventLog:

You have to agree, it looks pretty nasty.
Simple to fix though : you just have to rebuild and re-GAC. But make sure you do it properly, even if you have to un-GAC the old assembly.

No vpc network adapter enumerated or no host network adapter with provided MAC address found

The other day I had to transfer my entire machine (a Dell Inspiron E5500) to another identical machine, because I had a problem with the sound card of the first one.
I backed it up and restored this backup on the new machine and everything looked fine: I had all my settings, all my files and all my drivers.
Since I was working on a Windows Mobile application, the first thing I checked was if it would compile and execute correctly on the new machine.
So I opened my solution, clicked on debug and surprise, I get this error : “No vpc network adapter enumerated or no host network adapter with provided MAC address found”.
I looked everywhere to see what has been altered, until I finally gave up and looked up on Google for a solution.
What I found is that if you do not have the Virtual Machine Network Services installed, then you’ll get this error.

Furthermore, this driver is not downloadable anymore from the Microsoft web site because it comes with VPC 2007.
I already had VPC 2007 installed on my computer, so I went and checked if I had this driver.
Surprise again when I saw that I did!

Ok, we all know where this led me.
Uninstall VPC, reinstall VPC, reboot, re-reboot and many other vain attempts later, I still had the same error.
Basically all this had nothing to do with this driver.
What solved it was to delete the saved state of my emulator (.dess files located in C:\Users\you\AppData\Roaming\Microsoft\Device Emulator ) .
Apparently the emulators get bound to a network adapter on the PC, and a change in my hardware led to this error.

Lost one hour, but now I know.

Weird Error in orchestration

Sometimes, even though the orchestration does not show any error , when you build your project, you get a lot of them and when double-clicking the error it shows you something perfectly normal.

You can close VS ten times but it doesn’t help…

This thing drove me crazy for a while until I knew what to do.

What do you do then?

Well, you know the orchestration is formed of 2 parts, right?

One is XML of type <om:MetaModel  xmlns:om=”http://schemas.microsoft.com/BizTalk/2003/DesignerData”/> and the other is in X# (or Xlang if you want).

If you look at the Xlang part, you’ll see that your error is showing there instead of the relevant piece of code.  However, in the XML, the code appears and not the error.

The conclusion is that it’s the XML part that builds the Xlang part and not the opposite.

Great! Now what?

Edit the orchestration, get rid of the second one (basically everything below the #endif // __DESIGNER_DATA line), when rebuilding the project, it will behave as normal – showing no errors (provided that you really don’t have any error there).

Now if after building you open your orchestration with the XMLEditor (right click -> open with -> XMLEditor), you’ll see that the Xlang part has not been generated…

The thing is that the X# won’t be generated unless you change something in the orchestration.

Just open any shape like an expression shape and add a random space anywhere and that will do the trick.

Edit again and you’ll see the X#.

#if __DESIGNER_DATA#error Do not define __DESIGNER_DATA.<?xml version=“1.0“ encoding=“utf-8“ standalone=“yes“?>

<om:MetaModel MajorVersion=“1“ MinorVersion=“3“ Core=“2b131234-7959-458d-834f-2dc0769ce683“ ScheduleModel=“66366196-361d-448d-976f-cab5e87496d2“ xmlns:om=“http://schemas.microsoft.com/BizTalk/2003/DesignerData“>

…</om:MetaModel>

#endif // __DESIGNER_DATA          <– Everything below this line should be removed
