    • Resources
  • 70-536 Exam Basics
    • Exam Objectives and Matrix
      • http://www.microsoft.com/learning/en/us/exams/70-536.mspx
    • Approximately 50-60 questions
    • Mostly multiple choice
    • Passing score 700/1000
    • Offered in 3 different programming languages
      • VB.NET 2005
      • C# 2005
      • C++ 2005
  • Exam tips
    • Read the question!!!!
      • What are you being asked for?
      • How many options do you have to choose
      • Each question is on its own, does not relate to previous questions
    • On code segments, play spot the difference
    • Check the parameters and logic. Don’t assume
    • Know when to use particular classes
    • Finally, if it is old tech vs new, new is probably the answer 
  • Whats in 70-536
    • .NET Classes
      • Specifically the System namespace
    • Things to know
      • New features of 2.0 vs 1.1
      • Command line tools
      • Tracing & debugging
      • Code security
  • Breakdown of the exam
    • Security 20%
    • Serialization 18%
    • System Types and Collections 15%
    • Configuration Management, Diagnostic, and Installation Features 14%
    • Service Processes, Threading and Application Domains 11%
    • Interoperability, Reflection and Mailing 11%
    • Globalization, Drawing, Text Manipulation 11%
  • Security
    • Code Access Security permission sets (Nothing all the way to Full Trust)
    • Caspol – command line tool for setting and viewing code access security
    • AccessControl class – for managing access control lists
    • Encrypting and Decrypting
    • Symmetric vs Asymmetric cryptography (3DES, RSA for example)
  • Security
    • Permission Classes
      • DataProtectionPermission
      • EnvironmentPermission
      • FileIOPermission
      • IsolatedStoragePermission
  • Security
    • Policy Classes
    • Identity and Principal types (Windows, Generic, Custom)
    • IIdentity Interface (Name property, IsAuthenticated boolean function)
    • IPrincipal Interface (Identity property, IsInRole method)
  • Serialization
    • Serialization
        • Apply Serializable Attribute to serialize all properties
        • Apply NonSerialized attribute to exclude properties
        • Implement ISerializable interface to customize serialization
    • Formatter
        • Expose Iformatter interface
        • Implement Serialize and Deserialize methods
    • BinaryFormatter (for compact storage)
    • SOAPFormatter (for XML format, works across firewalls)
    • Use XMLSerializer to serialize an object to a specific XML format
  • Serialization
    • Retrieve File, Directory and Drive information (FileInfo, DirectoryInfo, DriveInfo classes)
    • Streams
      • Stream (abstract class)
      • FileStream (access to files)
      • MemoryStream (access to memory buffers)
      • BufferStream (access to streams that do not support buffering, you may need it for custom streams)
  • Serialization
    • Readers and Writers
      • TextReader /TextWriter(abstract class)
      • StringReader/StringWriter (reads from a string)
      • StreamReader/StreamWriter (data in text format to a stream) BinaryReader/BinaryWriter (data in binary format to a stream)
    • Compression
    • DeflateStream, GZipStream (GzipStream uses standard algorithm and is the preferred compression class)
  • System Types & Collections
    • Nullable types
    • Generic types
    • Generic Collections
  • System Types & Collections
    • Specialised Collections
      • ListDictionary
      • HybridDictionary
      • HashTable
      • Stack
    • Interfaces
    • Creating Event Handlers
  • Service Threading & Domains
    • Creating a class that runs as a service
      • Create Windows Service Project
      • Create service that inherits ServiceBase class
      • Override OnStop and OnStart methods of class
    • Install a service
      • Create installer class in service project that inherits System.Configuration.Install.Installer
  • Service Threading & Domains
    • Launching a method in a thread
    • Pass Parameters to a thread
      • ThreadStart does not accept parameters
      • ParameterizedThreadStart accepts one parameter but is not type safe
    • Thread Pool – for running many small jobs in threads
    • Application Domains – isolate applications
  • Diagnostics
    • Writing and reading to and from event logs
    • Retrieving information about processes
    • Using Mscorcfg.msc (.NET Framework Configuration Tool) for managing assemblies in the GAC, adjusting Code Access Security
  • Debug
    • Trace Listeners
      • DefaultTraceListener (writes to output window, fails go to message boxes used in development only, not production)
      • TextWriterTraceListener (writes to a TextStream good for file output)
      • EventLogTraceListener (writes to windows event log)
    • TraceSwitch (0-Off;1-Error;2-Warning;3-Info;4-Verbose)
    • Debugging (Assert, Write, WriteLine, WriteIf, WriteLineIf)
    • Performance counters
    • Retrieving management information from WMI
  • Interop
    • Exposing .Net components to COM
      • Need a default constructor that takes no arguments
      • Uses System.RunTime.InteropServices
      • Generate strong name with Sn.exe
      • Add reference to strong name in .config file (AssemblyKeyFile)
        • Choose Register for COM Interop OR manually register and generate type library using RegAsm.exe
        • Expose class members through an interface
    • Calling COM from .Net
        • Register COM dll with regsvr32
        • Add reference to dll in project, Visual Studio generates a proxy
        • Invoke component by creating a runtime callable wrapper (i.e. instance of proxy class)
  • Interop
    • Calling COM from .Net using Type Library Importer (Tlbimp.exe) to create an interop assembly that can be called by .Net
      • tlbimp myTest.tlb /out:myTest.dll
    • Using Platform Invoke and DllImport decoraction to call Windows APIs
  • Reflection
    • Reflection and Reflection.emit for creating and reading Metadata (MSIL)

    • System.Drawing (Pens, Fonts, Brushes)
      • To access the graphics of a form you must override the OnPaint method of the form
    • Graphics Class
  • Text

    • Regex – to use regular expressions
    • Encoding and Decoding
      • ASCIIEncoding
