What is Software Architecture and Why Architecture is important?



Software Architecture is defined to be the rules, heuristics and patterns governing:

·         Partitioning the problem and the system to be built into discrete pieces
·         Techniques used to create interfaces between these pieces
·         Techniques used to manage overall structure and flow
·         Techniques used to interface the system to its environment
·         Appropriate use of development and delivery approaches, techniques  tools

Why it is important?

The primary goal of software architecture is to define the non-functional requirements of a system and define the environment. The detailed design is followed by a definition of how to deliver the functional behavior within the architectural rules. Architecture is important because it:

·                  Controls complexity
·                  Enforces best practices
·                  Gives consistency and uniformity
·                  Increases predictability
·                  Enables re-use.

ContextSwitchDeadlock was detected

Image
I have been writing an application that loads large amounts of data into the a database. The process of loading the data into the database goes through several steps requiring a considerable amount of time to complete. The long processing time is not a matter of concern from the application stand point. However, frequently the application throws a "ContextSwitchDeadlock was detected" message that says the following: Message: The CLR has been unable to transition from COM context 0x20450a0 to COM context 0x20452f0 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives ...

Visual Studio setup and deployment projects

This article describes the basics of Visual Studio setup and deployment projects. Subsequent articles will cover advanced topics, including more on custom actions, .NET installer classes, and how to build an upgrade for the product. Introduction Setup and deployment projects have always been a part of the Visual Studio.NET environment. Setup projects can be used to build various deployment packages, most notably Windows Installer setups packaged as MSI files. I’ll start with a basic setup that installs a C# Windows forms program and adds a shortcut to it. First, select  Setup Project , grouped under  Setup and Deployment  in the  Other Project Types  section. Choosing this will give you an empty project for adding your deployment units. With the project selected in Solution Explorer, the  View->Editor  choice gives you a selection that includes  File System  – this is where you add your files and shortcuts. Application Folder ...
