Visual Studio 2010 Beta 1 - Test Drive

Finally we got VS 2010 Beta! I have just installed it and had a test drive of it. Look and feel is relay cool, seems more productive with lot of built-in functionality.

·         Aims to become a tool for everyone involved in Application Lifecycle Management (ALM) – from architects to developers, from project managers to testers. Not just for developers.


·         Unified Development and Database product editions.

Design & Architecture

·         Architecture Explorer – to discover and identify existing code assets and architecture in number of ways including graphs, stacked diagrams and dependency matrices.


·         Ability to create and share various types of diagrams like use case, activity and sequence diagrams.


·         Modeling tools that are tightly integrated with code and thus helps in keeping model and code in sync.


·         Architectural Validations - Ways to put constraints on code using models and doing validations at the time of check-ins and builds.


·         Architecture Layer Diagram – One of the most useful and simple tool getting introduced. It allows representing your application architecture in form of layers and showing dependencies between them. It also allows to map physical components like classes, namespaces etc. to map to these layers. After all mappings you can validate whether the code meets the expected mappings and constraints.


·         Microsoft joins OMG and UML gets introduced in Visual Studio 2010.


·         Support for UML 2.1.1 – 5 out of 13 diagrams – use case, component, activity, class and sequence diagrams.


·         Ability to keep all the UML diagrams in sync so that a change in one automatically reflects on others.


·         UML design tool is developed using DSL toolkit.


·         Will be interoperable with Visio 1.1 templates.


·         Supports Top to bottom design approach.


·         Supports Bottom to top design approach – reverse engineer. Filter based on namespaces, number of level deep.


·         Model Explorer – Similar to Solution Explorer, this allows you to explore all the models you have created which includes objects created as part of various UML diagrams – logical view.


·         Ability to create a Sequence Diagram from existing source, simply by right clicking in the VS code editor and selecting "Generate Sequence Diagram..."


·         Parallel Programming: To better utilize power of multi-processor and multi-core machines, .NET 4.0 will add support for parallel programming using PLINQ, Task Parallel Library and Coordination Data Structures. The debugger has been enhanced to identify concurrency issues. Two new features added are MultiStack and a Task List views. Introduction of concurrency analysis report for performance analysis of applications.

Quality/ Testing

·         Test Impact View - Identify and run only the tests impacted by a code.


·         Eliminating ‘no-repro’ bug  i.e. bugs that can’t be reproduced by providing tools for better collection of test data.


·         The Microsoft Test Runner Tool – a standalone tool that a tester uses to guide them through a series of steps to complete a test case. During the test run, this tool can take snapshot of test environment, application screenshots and even capture full video for assisting in reproducing bugs.

Source Code Management

·         Enhanced version control capabilities including gated check-in, branch visualization and build workflow.


·         Ability to perform constraints check on code during check-in based on Architecture Layer Diagram.

Project Management

·         Integration with Project Server for enterprise wide project management and new features for Agile project scheduling with Excel.

Crawler Kit

You can make your Boe-Bot Robot a Crawler by adding Boe-Bot Crawler kit, which can be additionaly purchased. The Crawler runs on standard Boe-Bot source code with only minor adjustments for ground speed. Sample PBASIC code is included in the documentation.

Gripper Kit
You can covert your Boe-Bot Robot in a lifter by Gripper Kit. Gripper Kit adds pick-up and carry capability to your Boe-Bot Robot. The Gripper features parallel plates that open, clamp onto and lift objects all with one cleverly utilized Parallax Standard Servo. Since the Gripper's servo plugs right into a servo port on the Board of Education, no additional battery pack is needed. The lightweight but sturdy aluminum, brass and plastic Gripper hardware weighs less than 7 ounces.

Sample Programme of Boe-Bot...

This program will prompt you for the number of pulses to send to the servos, and then the pulse width to transmit to each servo.  The program sends about 43 pulses per second, so 43 pulses would give you 1 second of run time, 86 would give you 2 seconds, and so on.  For speed control, 800 is about full speed counterclockwise, 700 is full speed clockwise, and 750 is stop.  If you want a wheel to go half speed counter clockwise, try about 775.  Half speed clockwise, would be about 725, and so on.

RFID (Radio Frequency Identification)

RFID has become very popular now a days, it being used as auto data collection (ADC) technology in many fiel
ds for example Passports, Libraries, School, Universities, Hospitals, Stores and Museums.

RFID is way of tracking objects using the radio waves typically called an RFID tag. Some tags can be read from several meters away and beyond the line of sight of the reader.

There are two major parts, One is an integrated circuit for storing and processing information, modulating and demodulating aradio-frequency (RF) signal, and other specialized functions.The second is an antenna for receiving and transmitting the signal.

On the other hand some say that using this technology for identification is a security threat, for example countries that put RFID in passports include Norway, Japan, most EU countries including Ireland and UK, Australia and the United States, Serbia, Republic of Korea.
