Exemplos
O exemplo de código a seguir descreve um escopo denominado filtered_customer e acrescenta três tabelas ao escopo: Customer, CustomerContact e NewTable. Como as duas primeiras tabelas já existem no banco de dados do servidor, o método GetDescriptionForTable é usado para recuperar o esquema do banco de dados do servidor. São incluídas todas as colunas da tabela Customer, mas apenas duas colunas da tabela CustomerContact são incluídas. A tabela NewTable é definida pelo uso dos objetos DbSyncTableDescription e DbSyncColumnDescription e a tabela é criada no banco de dados do servidor (e nos outros bancos de dados sincronizados com ele). Para exibir esse código no contexto de um exemplo completo, consulte Como configurar e executar a sincronização de bancos de dados (SQL Server).

// Definition for Customer.

// Definition for CustomerContact, including the list of columns to include.
Collection<string> columnsToInclude = new Collection<string>();
columnsToInclude.Add("CustomerId");
columnsToInclude.Add("PhoneType");
