Due to the In-Memory OLTP enhancements in SQL 2014, there is metadata support added in the form of a new column: uses_native_compilation in the sys.all_sql_objects catalog view. When you use SMO to retrieve a database object (typically when you script it using the SSMS Generate Scripts wizard, for example,) it retrieves properties from such catalog views to populate the corresponding SMO properties such as IsSystemObject and IsNativelyCompiled.
Unfortunately the code in the CTP1 (after all, it is non-production ready status for a good reason ) has an issue because it does not consider that IsNativelyCompiled property is absent from the catalog views for older releases of SQL Server. You may see this today as an error when scripting objects from Management Studio 2014, or if you directly use SMO to script objects as well. Note that this issue is only when connected to SQL 2012 or SQL 2008; scripting objects for SQL 2014 instances will work just fine.
FYI the relevant portion of the call stack might look like this:
Microsoft.SqlServer.Management.Common.ExecutionFailureException: An exception occurred while executing a Transact-SQL statement or batch.
System.Data.SqlClient.SqlException: Invalid column name 'uses_native_compilation'.
