About Microsoft 70-485 dump

This exam is intended for developers with a minimum of two to five years of experience developing C# and XAML applications, including two or more years designing and developing Windows Store apps.
This exam measures your ability to accomplish the technical tasks listed below.
Develop Windows Store apps (15-20%)

  • Create background tasks
    Implement the Windows.applicationmodel.background classes; implement the IBackgroundTask interface
  • Consume background tasks
    Use timing and system triggers; keep communication channels open; request lock screen access; use the BackgroundTransfer class to finish downloads
  • Create and consume WinMD components
    Create a WinMD component in C#; consume a WinMD component; handle WinMD reference types; reference a WinMD component

Discover and interact with devices (15-20%)

  • Capture media with the camera and microphone
    Use CameraCaptureUI to take pictures or video, and configure camera settings; use MediaCapture to capture pictures, video and audio; configure camera settings; set media formats; handle media capture events; implement advanced photo capabilities, such as sequence mode, thumbnails and focus mode
  • Get data from sensors
    Determine the availability of a sensor (Windows.devices.sensors); add sensor requests to the app manifest; handle sensor events; get sensor properties; determine location via GPS; enable geofencing
  • Enumerate and discover device capabilities
    Discover the capabilities of a device (for example, GPS, accelerometer, near field communication and camera)
  • Implement device access
    USB; Bluetooth; Human Interface Device (HID); 3D printer support; Point of Service (PoS) devices

Program user interaction (15-20%)

  • Implement printing by using contracts and charms
    Implement the print contract; create a custom print template; construct a print preview; handle print pagination; implement in-app printing; expose printer settings within your app
  • Implement Play To by using contracts and charms
    Register your app for Play To; use PlayToManager to stream media assets; register your app as a PlayToReceiver; programmatically implement Play To functionality
  • Notify users by using Windows Push Notification Service (WNS)
    Authenticate with WNS; request, create and save a notification channel; call and poll the WNS; configure and implement push notifications by using Azure Mobile Services

Enhance the user interface (15-20%)

  • Design for and implement UI responsiveness
    Choose an asynchronous strategy for your app; implement the Task Parallel library for multi-processor utilisation; convert asynchronous operations to tasks
  • Create animations and transitions
    Apply animations from the animation library; create and customise animations and transitions, including XAML transitions; implement storyboards and transformations; utilise built-in animations for controls
  • Create custom controls
    Choose the appropriate base control to create a custom control template; style a control through control templates; design the control template to respond to changes in windowing modes
  • Design Windows Store apps for globalisation and localisation
    Implement .resw files to translate text; implement collation and grouping to support different reading directions; implement culture-specific formatting for dates and times

Manage data and security (15-20%)

  • Design and implement data caching
    Choose which types of items (user data, settings, app data) in an app should be persisted to the cache according to requirements; choose when items are cached; choose where items are cached (Microsoft Azure, Azure Mobile Services, remote storage); select the caching mechanism; store data by using LocalStorage and SessionStorage
  • Save and retrieve files from the file system
    Handle file streams; save and retrieve files by using StorageFile and StorageFolder classes; set file extensions and associations; save and retrieve files by using the file picker classes; compress files to save space; access libraries and KnownFolders, for example, pictures, documents, and videos; manage appearance of the file picker; improve searchability by using Windows Index; integrate OneDrive with apps; compare files; manage libraries; secure application data
  • Secure app data
    Encrypt data by using the Windows.Security.Cryptography namespace; enrol and request certificates; encrypt data by using certificates; revoke file permissions

Prepare for a solution deployment (15-20%)

  • Design and implement monetisation features in an app
    Set up a timed trial; set up a feature-based trial; set up in-app purchases; transition an app from trial to full; implement in-app purchases
  • Design for error handling
    Design the app so that errors and exceptions never reach the user; application class for global collection; handle device capability errors; handle asynchronous errors
  • Design and implement a test strategy
    Recommend a functional test plan; implement a coded UI test; recommend a reliability test plan (performance testing, stress testing, scalability testing, duration testing); implement unit testing in an app; simulate in-app purchases
  • Design a diagnostics and monitoring strategy
    Design profiling, tracing, performance counters, audit trails (events and information) and usage reporting; decide where to log events (local vs. centralised reporting)
  • Evaluate and configure for Windows store deployment
    Configure app options to submit to store, such as age restrictions, privacy statement, permissions, images and contact information; create application files, resource files and application bundles; verify application readiness by using the Windows Application Certification Kit (WACK)
