This document discusses .NET RIA Services and SQL Data Services. It begins with an introduction to Class-A, a Microsoft development training company, and the presenter Dennis van der Stelt. The agenda is then outlined, covering SQL Data Services, .NET RIA Services, and a demo. SQL Data Services are explained in more detail and code examples are provided. .NET RIA Services are then discussed, covering the vision and goals of simplifying RIA development and bringing ASP.NET productivity to the client. The multi-tier application model and an example demo are presented before closing with questions.

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

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, …

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

17. Roadmap
• SQL Data Services
– Unknown, only that it supports TDS
• .NET RIA Services
– May CTP available, new one in July
– PDC09 bits will run on Astoria
– First part of 2010 : RTW

18. Summary
• .NET RIA Services offer
– Better n-tier support
– Rapid Application Development
– A pattern that scales and grows
– Services for additional features
And remember, this will run on SDS
