How do I reference a previously deployed schema within a new BizTalk project?

I have a BizTalk 2009 environment with a running application (call it A1) that contains a schema (S1). S1 has a few promoted properties defined in PropertySchema.xsd. A1 is fairly simple, it has a Receive Port that polls a database for (debatched) S1 messages, and a Send Port that writes them to file.

I am now developing a new application (A2), and want it to contain an orchestration that has a d开发者_运维问答irect subscription to the MessageBox to get some S1 messages with a certain promoted property value.

What is the correct approach to make the S1 schema, and its promoted properties, available for use within A2?

Should I:

• Add S1.xsd to the Visual Studio project for A2? (And what about PropertySchema.xsd?)
• Add Reference from the A2 project to the A1 assembly?

Or is there another way I haven't thought of? Thanks.

I would suggest create a Shared Application, which can contain all the Shared artificats.
