  • 5. SQL Data Services
  • 6. SQL Data Services SqlConnectionStringBuilder connStringBuilder = new SqlConnectionStringBuilder(); connStringBuilder.DataSource = "myserver.data.dev.mscds.com"; connStringBuilder.InitialCatalog = "mydatabase"; connStringBuilder.Encrypt = true; connStringBuilder.UserID = "flitsservice“; connStringBuilder.Password = "****"; string createTableSql = @"CREATE TABLE [dbo].[tbl_Person] ( [FirstName] NVARCHAR(64) NOT NULL, [LastName] NVARCHAR(64) NOT NULL CONSTRAINT [personName_PK] PRIMARY KEY CLUSTERED ( [FirstName] ASC, [LastName] ASC ) )";
  • 7. SQL Data Services using (SqlConnection conn = new SqlConnection(connStringBuilder.ToString())) { conn.Open(); using (SqlCommand cmd = conn.CreateCommand()) { cmd.CommandText = createTableSql; cmd.CommandType = CommandType.Text; cmd.ExecuteNonQuery(); cmd.CommandText = "select * from tbl_Person where FirstName = 'Dennis'"; using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { Console.WriteLine("First Name: {0}", reader["FirstName"]); } reader.Close(); } }

  • 9. .NET RIA SERVICES
  • 10. Vision and goals • Simplify RIA development – n-tier is hard, and un-natural • Bring ASP.NET/RAD-style productivity to RIA development – Focus on end-to-end scenarios and solutions
  • 11. End-to-End Data • Beyond accessing and editing rows – App-specific custom operations – Data shaping (sorting, paging, filtering) – Rules (validation, authorization, conflict handing) – Batching and offline
  • 12. Multi tier application model Services Browser HTML Rich Internet Application Application Web Presentation Network Logic App Logic Services Data Access Layer Services Other Applications DB
  • 13. DEMO
  • 14. A Prescriptive Pattern DomainContext: Bindable Data DomainService: CRUD + App Logic class Catalog EntityList<Product> Products { get } void LoadProducts(IQueryable<Product>) void ToggleSale(Product) Data Model + Metadata + Shared Code class Product Data members + Validation void ToggleSale() class Catalog IQueryable<Product> GetProducts() void UpdateProduct(Product, Product) void ToggleSale(Product) Validation and authorization rules, Application workflows, … Data Model class Product Application Presentation Logic Network Services App Logic Data Access Layer DB
  • 15. A Pattern that Scales and Grows Databases ADO.NET, ORMs (LTS, EF, …) App Logic CLR Lists/Objects Repository (nHibernate, …) XML, JSON, Binary Unit Test Code Services REST/SOAP (Azure, …)
  • 16. What didn’t we cover? • Authentication – Both Windows & Forms based • Enhanced SEO capabilities – Not yet fully functional in current bits • Business application template • Linq2Sql & Azure capabilities • OOB & Offline synchronization
