SQL Server 2012 Deploy Database to SQL Azure...

Question

I have spent many days trying to copy a simple test database from my PC to SQL Azure but with little success.  Then I installed SQL Server 2012 and see a new task:
Deploy Database to SQL Azure...  It looks like an automated extraction to DAC and then creating the Azure database all in one step.
I was elated, but got hit with the following three types of errors.
One or more unsupported elements were found in the schema used as part of a data package.
Error SQL71564: The element Extended Property: [dbo].[Accounts].[Address].[MS_Description] is not supported when used as part of a data package (bacpac).
Error SQL71564: Table Table: [dbo].[Activities] does not have a clustered index.  Clustered indexes are required for inserting data in this version of SQL Server.
Error SQL71564: Element User: [NT AUTHORITY\NETWORK SERVICE] has an unsupported property AuthenticationType set and is not supported when used as part of a data package.
 (Microsoft.SqlServer.Dac)
May I know what I can do on the on-premise database to rid of the first and third error?
Thanks.

Hello,
1) Remove the Extended Property from the (?) column Address in table Accounts.
BTW, for small databases it's sometimes easiere to generate a script for the database (and modify it slightly) instead of using the Wizard

What is Extended Property?   What is this .MS_Description?   I can't see it in the table designer or the Column Properties.  (I don't know whether this was corruption caused by Data Sync I used earlier.)  How do I remove it.
Of all the methods of copying SQL Server to Azure SQL, this one gives the least mistakes.  If I can solve this Extended Properties thing hopefully I can migrate the database over.
