.net 4.0 Adoption Speed

Question

What is the adoption speed of .net 4.0?

When will it be in Windows Update?

I heard that it is less than 3.5, does that mean if I install .NET 4.0, it will reduce the space used by the framework?

If I create an application in 3.5 and run on a computer with 4.0, will my application get some of the optimizations that 4.0 uses?

Answer 1

• You will find that most people probably will not install it until they use something that they need.

• This is an optional Windows update, as far as I know. Optional updates are generally ignored by many people.

• The installation is small, but it will not make your .NET installation smaller. It will increase.

• Not. It will run on the .NET 3.5 platform. To use the functions of .net4, etc., you must convert it to .net4.

Answer 2

In terms of size, the Net Framework 4.0 client profile is what your users will need to install to run 4.0 applications and download it at 41 MB ( http://www.microsoft.com/downloads/details.aspx?familyid=E5AD0459 -CBCC-4B4F-97B6-FB17111CF544 & displaylang = en ), so it’s not quite “small” yet. This is much better than the 3.5 client profile, which varied in size depending on what you just installed, but maybe 100 MB +

Answer 3

If people install the web installer over the Internet, http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=5765d7a8-7722-4888-a970-ac39b33fd8ab , which is 868 KB, may be the best experience. This is a small installer that quickly starts and runs. Then during installation, it downloads only what you need for the machine on which it works. For example, on x86 downloadd is about 28 MB.

In addition, the stand-alone instructions include links for stand-alone x86 and ia64 installers. Although, if you cannot guarantee that you will only support x86 computers, for example, you should use the standalone installer to install on the Internet or x64. You cannot install x86 only on x64 computers.
