What is an Assembly

0 comments
Today we are talking about assembly , Here is some good definition of Assembly so you can understand it well.
Assembly is unit of deployment like EXE or a DLL.
An assembly consists of one or more files (dlls, exe’s, html files etc.), and represents a group of resources, type definitions, and implementations of those types. An assembly may also contain references to other assemblies. These
resources, types and references are described in a block of data called a manifest.The manifest is part of the assembly, thus making the assembly self-describing.
An assembly is completely self-describing.An assembly contains metadata information, which is used by the CLR for everything from type checking and security to actually invoking the components methods. As all information is in the
assembly itself, it is independent of registry. This is the basic advantage as compared to COM where the version was stored in registry.
Multiple versions can be deployed side by side in different folders. These different versions can execute at the same time without interfering with each other. Assemblies can be private or shared. For private assembly deployment, the
assembly is copied to the same directory as the client program that references it. No registration is needed, and no fancy installation program is required. When the component is removed, no registry cleanup is needed, and no uninstall
program is required. Just delete it from the hard drive.
In shared assembly deployment, an assembly is installed in the Global Assembly Cache (or GAC). The GAC contains shared assemblies that arglobally accessible to all .NET applications on the machine.

What is project management

0 comments
This topic is meant specially for .NET programmers who are looking for better position rather than simple programmer jobs. Project management is not everybody’s cup of tea. I have seen 10 year good decent technical guys do not get this position easily. But street smart programmers with average technical guys do really well. How much ever I try to cover this topic in this book.....it has so many variations that it’s really difficult to predict every scenario of project management interview. But definitely I will try to cover the basics by which you can at least get a feel of what is asked.

Project management is the discipline of planning, organizing and managing resources to bring about the successful completion of specific project goals and objectives.

A project is a finite endeavor (having specific start and completion dates) undertaken to create a unique product or service which brings about beneficial change or added value. This finite characteristic of projects stands in sharp contrast to processes, or operations, which are permanent or semi-permanent functional work to repetitively produce the same product or service. In practice, the management of these two systems is often found to be quite different, and as such requires the development of distinct technical skills and the adoption of separate management philosophy, which is the subject of this article.

The primary challenge of project management is to achieve all of the project goals and objectives while honoring the project constraints. Typical constraints are scope, time and budget. The secondary—and more ambitious—challenge is to optimize the allocation and integration of inputs necessary to meet pre-defined objectives. A project is a carefully defined set of activities that use resources (money, people, materials, energy, space, provisions, communication, motivation, etc.) to achieve the project goals and objectives.
Applying knowledge, skills, tools, techniques in project and deliver project deliverables is a short definition
