DBCoreTest app referenced in docs is missing

[bdschaap]

The DBCoreTest app referenced in the docs isn't available in this github repo. The code for DBTest exists but that uses System.Data.SqlClient rather than Microsoft.Data.SqlClient. Please make the code for DBCoreTest available. Also, please make a build artifact so it's available similar to the DBTest one found here.

Thanks!

DBCoreTest is DBTest with the following modifications:

1. The -type command-line switch is absent and the ODBC and OLE DB connection types are not implemented.
2. System.Data.SqlClient is replaced by Microsoft.Data.SqlClient for the .NET connection.
3. A -wait switch was added to have some way of testing the "Trace an already running app" scenario in the docs.

We are not ready to release a compiled app at this point. But we can get the source code up in a project.
