The document discusses the basics of software architecture for .NET developers. It defines software architecture as the structure and design of an application, including its components and how they are connected. A good architecture provides advantages like compatibility, extensibility, reliability and maintainability. The software architect must take implicit requirements into account, such as scaling and future needs, even if stakeholders are not aware of them. Architects should understand object oriented principles, design patterns, emerging technologies and focus on reusability.

- 2. Software Architecture is:Structure and design of the application/systemComponents, and how they are implementedConnectors – the relationship between the componentsReducing complexity through abstractionBreaking an application into distinct features that overlap in functionality as little as possibleFunctions can be optimized independentlyFailure of one function does not cause the others to fail

- 5. Implicit RequirementsAn Analogy: Implicit requirements are those that engineers automatically include as a matter of professional duty. Most of these are requirements the engineer knows more about than their sponsor. For instance, the original Tacoma Narrows Bridge showed that winds are a problem for suspension bridges. The average politician is not expected to know about this, however. Civil engineers would never allow themselves to be in a position to say, after a new bridge has collapsed, “We knew wind would be a problem, but you didn’t ask us to deal with it in your requirements.”Source: MSDN Architecture Article: Are We Engineers? or Crafts People? http://msdn.microsoft.com/en-us/library/bb508955.aspx
- 6. Implicit RequirementsIt is the “duty” of the software architect to determine potential problems or risks with a design and mitigate or eliminate these risksThe stakeholders of the project, don’t necessarily understand these risks nor do they necessarily understand their importance to the long term success of the project
- 7. Implicit Understanding Of RiskThis will lead to a better analysis and resolution of risk, including:ScalingCompatibilityFuture Maintenance and EnhancementsUsability IssuesStakeholder Buy-In and SupportProper Business Processes In Placeetc…
- 8. For .NET DevelopersSolid Understanding of Object Oriented Programming Objects, Instances, Inheritance, Abstraction, Encapsulation (Interfaces), Polymorphism, Decoupling, etc.NET Design PatternsVery useful patterns to understand include (Strategy, Façade, Adapter, and Singleton)Keep up to date on the latest technologySOA, WF, WPF, WCF, LINQ, etc
- 9. For .NET DevelopersIncrease Your Productivity and EffectivenessDevelop application components that are re-useableLook to re-use existing components Always consider modularity and decouplingLook at third party components (Infragistics, Telerik, etc)Consider ORM mapping tools such as LLBL Gen Pro
- 10. For .NET DevelopersUnderstand the Value of GenericsGenerics make type parameters possibleDefers the type of a method or object until it is instantiated (ex: List(Of T) Ex:) New List object is typed to be of type animalUnderstand the Value of ReflectionSystem.Reflection namespaceLoad objects at run time, get a list of methods and properties of objects at run time (even private ones) and call themMany practical uses, including the ability to create a “Pluggable Architecture”
- 11. For .NET DevelopersMicrosoft Patterns & PracticesEnterprise LibraryProvides common application blocks to be used within your application for Data Access, Cryptography, Caching, Exception Handling, Logging, Security, and more.Software Factories Architectural factories for building your application, including, Smart Client, Web Service, and Mobile ClientRed-Gate .NET Reflector is a Cool Tool!Allows you to view, navigate, and search through the class hierarchies of .NET assembliesLook at the code behind the objects in .NET Framework classes to see how they work

Editor's Notes
- #3: ComponentsWhich components?How are they implemented?Reducing complexity through abstractionBreaking an application into distinct features that overlap in functionality as little as possibleFunctions can be optimized independentlyFailure of one function does not cause the others to fail
- #9: Keep up to date on the latest technology – Not always necessary to have intimate knowledge of new technology, but useful to have an understand of the technology to get an idea of where it may assist or be useful within a software system
- #11: This is a very quick introduction about reflection and generics.. Many resources on the web available.
