Skills measured
This exam measures your ability to accomplish the technical tasks listed below. The percentages indicate the relative weight of each major topic area in the exam. The higher the percentage, the more questions you are likely to see on that content area in the exam.

From 30 April 2014, the questions on this exam include content covering Visual Studio 2013 and updates to Microsoft Azure.

Please note that the questions may test on, but will not be limited to, the topics described in the bulleted text.

Accessing data (20-25%)

Implement transactions
Manage transactions by using the API from System.Transactions namespace; implement distributed transactions; specify transaction isolation level

Implement data storage in Azure
Access data storage in Azure; choose data storage mechanism in Azure (blobs, tables, queues, SQL Database); distribute data by using the Content delivery network (CDN); handle exceptions by using retries (SQL Database); manage Azure Caching

Create and implement a WCF Data Services service
Address resources; implement filtering; create a query expression; access payload formats (including JSON); use data service interceptors and service operators

Manipulate XML data structures
Read filter, create, modify XML data structures; Manipulate XML data by using XMLReader, XMLWriter, XMLDocument, XPath, LINQ to XML; transform XML by using XSLT transformations

Preparation resources
Transaction isolation levels
WCF Data Services
XML documents and data

Querying and manipulating data by using Entity Framework (20-25%)
Query and manipulate data by using the Entity Framework

Query, update and delete data by using DbContext; build a query that uses deferred execution; implement lazy loading and eager loading; create and run compiled queries; query data by using Entity SQL; perform asynchronous operations using Entity Framework; map a stored procedure

Query and manipulate data by using Data Provider for Entity Framework
Query and manipulate data by using Connection, DataReader and Command from the System.Data.EntityClient namespace; perform synchronous and asynchronous operations; manage transactions (API); programmatically configure a Data Provider

Query data by using LINQ to Entities
Query data by using LINQ operators (for example, project, skip, aggregate, filter and join); log queries and database commands; implement query boundaries (IQueryable vs. IEnumerable); implement async query

Query and manipulate data by using ADO.NET
Query and manipulate data by using Connection, DataReader, Command, DataAdapter, DataSet; perform synchronous and asynchronous operations; manage transactions (API)

Create an Entity Framework data model
Structure the data model using table per type, table per class, table per hierarchy; choose and implement an approach to manage a data model (code first vs. model first vs. database first); implement POCO objects; describe a data model by using conceptual schema definitions, storage schema definition, mapping language (CSDL, SSDL, MSL) and Custom Code First Conventions

Preparation resources
Entity Framework
Loading related entities

IQueryable Interface

Designing and implementing WCF Services (15-20%)

Create a WCF service

Create contracts (service, data, message, callback and fault); implement message inspectors; implement asynchronous operations in the service

Configure WCF services by using configuration settings
Configure service behaviours; configure service endpoints; configure bindings including WebSocket bindings; specify a service contract; expose service metadata (XSDs, WSDL and metadata exchange endpoint); configure message compression and encoding

Configure WCF services by using the API
Configure service behaviours; configure service endpoints; configure binding; specify a service contract; expose service metadata (XSDs, WSDL and metadata exchange); WCF routing and discovery features

Secure a WCF service
Implement message level security, implement transport level security; implement certificates; design and implement multiple authentication modes

Consume WCF services
Generate proxies by using SvcUtil; generate proxies by creating a service reference; create and implement channel factories

Version a WCF service
Version different types of contracts (message, service, data); configure address, binding and routing service versioning

Create and configure a WCF service on Azure
Create and configure bindings for WCF services (Azure SDK—extensions to WCF); relay bindings to Azure using service bus endpoints; integrate with the Azure service bus relay

Implement messaging patterns
Implement one way, request/reply, streaming and duplex communication; implement Azure Service Bus and Azure Queues

Host and manage services
Manage services concurrency (single, multiple, reentrant); create service hosts; choose a hosting mechanism; choose an instancing mode (per call, per session, singleton); activate and manage a service by using AppFabric; implement transactional services; host services in an Azure worker role

Preparation resources
Windows Communication Foundation Services and WCF Data Services in Visual Studio

Forward-Compatible data contracts

Creating and consuming Web API-based services (15-20%)

Design a Web API
Define HTTP resources with HTTP actions; plan appropriate URI space and map URI space using routing; choose appropriate HTTP method (get, put, post, delete) to meet requirements; choose appropriate format (Web API formats) for responses to meet requirements; plan when to make HTTP actions asynchronous; design and implement routes

Implement a Web API
Accept data in JSON format (in JavaScript, in an AJAX callback); use content negotiation to deliver different data formats to clients; define actions and parameters to handle data binding; use HttpMessageHandler to process client requests and server responses; implement dependency injection, along with the dependency resolver, to create more flexible applications; implement action filters and exception filters to manage controller execution; implement asynchronous and synchronous actions; implement streaming actions; implement SignalR; test Web API web services

Secure a Web API
Implement HTTPBasic authentication over SSL; implement Windows Auth; prevent cross-site request forgery (XSRF); design, implement and extend authorisation and authentication filters to control access to the application; implement Cross Origin Request Sharing (CORS); implement SSO by using OAuth 2.0; configure multiple authentication modes on a single endpoint

Host and manage Web API
Host Web API in an ASP.NET app; self-host a Web API in your own process (a Windows service) including Open Web Interface for .NET (OWIN); host services in an Azure worker role; restrict message size; configure the host server for streaming

Consume Web API web services
