This schema has the same type name as its namespace

After installing BizTalk 2013, just to check I started to create a project with name as Test. Then added a schema named Test with Root tag named as Test and two elements. Signed the project and tried to build it and following error appeared.

To find out the problem,  I went through the properties of the schema and found that Namespace and Type name is same. Well I don’t  the exact reason but it seems having same namespace and type name causes ambiguity in resolution. 

Why it happened:  

Namespace (Project Name) and Type Name (Schema name) were same

What to do : 

Rename the schema and Type Name Or delete the schema and create new schema with name different than that of Project Name.
