Recently, I moved into new BizTalk assigment and I was very happy but my happiness shattered completely as the Architecture was completely screwed up (I apologies, being 4+ yrs of exp, I don't hold qualification to comment anything on architecture but personall speaking it was screwed up :( ).
It was something like integrating 16 messages and without using any percentage of brain, people have created 16 orchestrations and that to in 16 different BizTalk projects. uff.. this made me remember my first year of career when I used to do POCs and its giving me the feeling they as well doing POCs and then moving their POCs to UAT server and finally to test server.
But truly speaking, they have a valid reason i.e. "Time constraint" so they haven't wasted single second for investigation and finally it ended-up in 12-14 hrs daily in office, effort shoot up by 200+%.
And this is not enough, to add further happiness I got the wonderful surprise on the next day itself, that the other guy is moving out and I have to carry forward the remaining development and production deployment. Soon I realized deployment will going to be real pain in a$$.
I left with 2 options: first resigning from the company, secondly to do something that will largely help me, I am not much worried for anything else.
So, I thought of doing deployment programatically i.e. using WMI.
Following are the task, I am going to achieve by deployment application:
1. Creating Host (3 Host)
2. Creating Host Instance (3 Host Instance)
3. Adding Send Handler (for 4 Adapters)
4. Adding Receive Handler (for 3 Adapters)
5. Creating BizTalk Application (4 New applications)
6. Adding Reference to applications (few numbers)
7. Installing BizTalk Assemblies (16+)
8. Loading Binding files (16+)
9. Few more minor activities.
Frankly speaking, If I have to do these many task I would rather prefer to quit my job and look for the new one.
The day I have finished my the coding for deployment, I cried tears of joy :)
WMI Application extensively uses:
System.Management namespace
So keeping this Bullshit aside let go straight to the code :
public partial class HostingTask
{

private const string MSBTS_HostSetting = "MSBTS_HostSetting";
