.netframework  

I think .net framework is provide a recommended plateform or environment to that software which you going to instal on your computer.. so many software ask for instaling .net frameworkk before instaling any software..

The short answer is that it allows you to run applications that are written .NET Framework based. Every single day programs are growing in popularity of languages like C# and VB.NET. Without going into too much detail, if a program is created in these languages, it requires the .NET Framework to be installed on the Windows-Based computer that runs them. If there is none, then Windows won't be able to 'read' half of all your programs you're using.
It wouldn't hurt you to install it before installing certain softwares, but usually, you wil get prompt for it while installing a certain program, or when you try to start the program.

Microsoft's windows 32 is produced using .net framework .
there two of this type .
.net framwork or java.
microsoft have to choose between them and as compared to java .net framework is more flexible and language independent.so the changes that you make to a code can be flexible i.e can be used for some other software to be created.
thats all i know......

.Net Framework is a Run Time Environment. When a software made by .Net Framwork, it needs a library from the .Net Framwork to Run. .Net Framework translate Microsoft Intermediate Language ( Which is .net application ) by making Just In Time Compiler ( a component of .Net Framwork ) call a specisif function the application request. The Idea of .Net Framework is like java, so you can hope it's application will run at any platform as long as the platform have .Net Framwork installed on it.

Well, i kinda hazy about the ditail, but i think it is like that. I should learn more in college :(

Really a interesting topic that I wanted to know about this.After formatting the system, if we try to install some software we are being asked to install this software.Though I don't know about this, I will install and then proceed with the other software. From the responses of other members to this discussion, I am now able to understand the necessity of the .net frame work.Also for some installations, MDAC and Internet information services are required. I am unaware of these things also.Anyway thanks for starting this discussion as it helped me to know something about .net framework.

Every software was developed under any one of the technology platforms like windows, java, other supporting languages. While developing these softwares they use few library functions comes with programming. But while coming to real use our system may not have those library files to execute those developed softwares.

For example softwares developed using .net or c# need few library files (functions) in our system. .net framework is a package of library file to get read our system to execute various windows based application softwares.
