Error: Add new BTAHL7 Projects, Object Reference not set to an instance of an Object
Sometimes, when you try to add BTAHL7 Common Project to your solution you may encounter with the error “Object Reference not set to an instance of an Object”.
I am not sure how to resolve this error, but there is a simple alternative to this Error.
This error will fail to add the necessary common schemas (for eg: datatypes_25.xsd, segments_25.xsd, tablevalues_25.xsd) to your solution.
All of these schemas would generally be available in the following path. <drive>:\Program Files\Microsoft BizTalk 2010 Accelerator for HL7\Templates\Schemas\V2.X\
So, you can Create a new Empty BizTalk Project, Copy these common schemas to your project folder and Add them to the Project using Add Existing Item.
Please post if you have a solution to resolve this.
