Couple of years ago from now when I started working with BizTalk 2009. I was very excited and wanted to dig in more and more .
So I started with creating a BizTalk project in Visual Studio 2008, going through the Tutorials and following the instructions.
I successfully completed the tutorials(It is a big Achievement for a starter... :) ). Now it was time to try something on my own.
But that day I got error "Creating project ‘BizTalk project name’… project creation failed." --- Now this was a big issue for me!!!!
After some looking here and there(Google) I found the reason. The culprit was updates which had successfully done the other night.
Below is the link which acted as Saviour then :)
