1. Microsoft Enterprise Library 5.0
Welcome to Bob Brumfield’s talk on
Microsoft Enterprise Library 5.0
@ NT konferenca 2011
Please wait while the Setup Wizard prepares
to guide you through the presentation

3. Context Reusable components are important
Address common enterprise development challenges consistently across applications
Application Blocks are a form factor for reusable components
Reusable, testable, extensible and modifiable source code
+ docs, hands-on labs
Enterprise Library is a set of general purpose application blocks
Not specific to any one application type or architectural style
Can be used as-is or as a starting point for your own libraries or frameworks
WHEN IT COMES TO CODE WRITING, LESS IS MORE!
YOU SIMPLY CANNOT AFFORD NOT TO REUSE!

4. Enterprise Library – Big Picture

5. EntLib Design Goals Consistency Extensibility Ease of use Integration
Blocks are written with and used in common patterns
Extensibility
Pluggable extension points
Ease of use
Config tool, tons of docs, simple interfaces, labs, webcasts
Integration
Work well together or separately

6. Simplification inside and out
Key themes
Ease of use
Learnability
Less intrusive
Better testability
Simplification inside and out

7. No new blocks
Healthy code

13. A-la carte approach
You only need to use features relevant to you!

14. .NET 4.0 / VS 2010 Binaries Source Config tool Signed
Target .NET 3.5 SP1
Work unchanged in .NET 4.0 projects
Source
VS 2008 sln/proj targeting 3.5 SP1
VS 2010 sln/proj targeting 4.0
Config tool
Fully integrated editor in VS 2008
Launcher from VS 2010 (like WCF config tool)

15. Adding logging to your app in ~3 mins!
Ease of use! Demo
Adding logging to your app in ~3 mins!

16. Getting Enterprise Library objects

17. Config Experience New config tool IntelliSense in XML editor
Programmatic config support
New configuration sources

18. Config Tool Stories Usability: Improve intuitiveness & learnability
Simplicity: Reduce the number of design time assemblies
Extensibility: Simplify the way config for custom handlers/providers/blocks can be plugged into the config tool

19. Config Tool Experience Demo

20. Twelve Architecture &
Usage of EntLib

21. Fluent Configuration Interface
Motivation:
Customer requested a better way to configure EntLib programmatically
Make our own test cases more readable
Ref: Martin Fowler, Eric Evans.

22. Programmatic Config Experience Demo

23. Hierarchical / Redirected config
Use a non-default config store
Split config into multiple physical files
Combine them at runtime
Allows master + override style of config
Runtime version of environmental overrides

24. Logging Block Performance
Originally, planned to implement async logging
Perf analysis of the lower level operations of the logging block (v4.1) showed:
The formatter took 54% of the total time
Of this, the most expensive operations are:
11.76   Getting the machine name
9.63    Computing Severity textual representation
5.70    Undetermined mscorwks.dll work
5.17    Computing DateTime textual representation
4.46    StringBuilder.Append
4.10    Getting the process name

25. Higher Performing Logging – Preliminary Results
Formatter responsible for ~50% of the execution time
Improvements
N=1M
45% local improvement
upto 20% global improvement
53% local improvement

26. New in Data Access Application Block

27. Processing Results
Data Access block traditionally made it easier to call sprocs
Processing the results still means dropping back into classic ADO.NET code
Issue: how could we make it easier to consume the results of a sproc?

28. Introducing Data Accessors
Basic idea:
Instead of operating on data readers and data records that you get from a query, get back an IEnumerable<T>
Now we can do LINQ to Objects magic
Accessors
provide a higher level abstraction that combines the command, input mapping, output mapping, and result set management into a single object.
Note: Accessors are easily injectable

32. DAAB Accessors != ORM

33. Async DAAB Database API addition
Follows classic Begin/End async pattern
NonQuery
Scalar
Reader
XmlReader (SQL Server only)
Not supported on all databases

34. Async Data Access var db =
EnterpriseLibraryContainer.Current.GetInstance<Database>();
if(db.SupportsAsync) {
db.BeginExecuteScalar("Get Top Ten Products",
CompletionMethod); }
public void CompletionMethod(IAsyncResult async) {
int count = (int)db.EndExecuteScalar(async);
...

35. Policy Injection Application Block Goals
Separate cross-cutting concerns from business logic
Use interception and injection to apply policies at runtime
Provide a declarative way of specifying which policies are applied where
Define policies using configuration or attributes
Leverage other application blocks to implement common cross-cutting concerns
Validation, Logging, Authorization, Exception Handling, Caching, Performance Counters
Provide flexibility in interception mechanisms
Aspect-Oriented Programming (AOP )
