Most of the time we have provided with XML document to create BizTalk XSD schema in this case we can Generate XSD from given XML files.
here is the steps we need to follow.
1) First we need to execute the following script which comes with BTS 2009 and BTS 2006 this is located in the following Directory.
C:\Program Files (x86)\Microsoft BizTalk Server 2009\sdk\Utilities\Schema Generator ( for 64 bit machine).
C:\Program Files\Microsoft BizTalk Server 2009\sdk\Utilities\Schema Generator (32 bit machine).
with out executing this script if you try to Generate XSD schema you get the following error which is self explanatory.
Now fire up the VS.NET 2008 Right click the BizTalk project and select Add –>Add Generated Items as shown below.
Select the Generate Schemas from the list.
Now you need to select the Input Document type in my case i am going to use Well-Formed XML file.
