This example shows how to create a runspace that uses WS-Management-based remoting to run commands on the local host. This same code could be used to connect to a remote computer.
The structure seems obvious to system designers who have grown tired of single monolithic systems and want to break those systems up into components and services. What could be more natural than to break the system along the lines of data base managment?
Unfortunately this is a huge violation of the Single Responsibility Principle — or its big brother the Common Closure Principle.
These principles tell us to group together things that change together, and keep apart things that change for different reasons.
When you separate things that change for the same reasons, you have to make changes in many different places in the system.
So it’s a lot of work just to get anything working.
Moreover, when you group together things that change for different reasons, you expose the components of the system to collateral damage, thrashing, CM collisions, and a whole host of other problems.
So what’s the solution? First of all, I question whether the system needed to be partitioned into services.
Services are expensive and complicated, you should only create them if you absolutely need to. It’s always easier to live in a single process. Remember Martin Fowler’s first law of distributed objects: Don’t distribute your objects.
Many systems could be streamlined, and development made much faster, if the system designers paid more attention to the Single Responsibility Principle.
These tools can help make a developer's job a little bit easier can be useful for our projects. Here is a list of tools that make it easy to write applications in the .NET environment.
Here we are going to design a regular expression pattern to validate email address which will check to make sure an e-mail address is a valid address, and in proper format means containing an username, at sign (@), and valid hostname.
Clonezilla is a PXE network boot used to clone multiple computers at once - much like norton ghost. Clonezilla Live is a bootable CD/USB image that can replace the need for a network boot server and image host, allowing you to clone a single machine on a local computer without a network.

SgmlReader was a source reference assembly from Microsoft which allows parsing Html as Xml -- that is, it takes poor, and even invalid Html and converts it to XHtml and gives you an XmlReader or XmlDocument from it.
