Why is the size of .NET Framework 4.0 installer smaller than 3.0/3.5?

As I can see, beta2 of .Net Framework 4.0 installation program is only 55MB, and it was 200+MB for .Net 3.5, What's happening?

A: 

This follow on from the work done to optimise the framework for the Silverlight plug-in.

.net is now 10 years old, new techniques and just some good old fashioned spring cleaning of the code is before performed on version 4, to (hopefully) give us a sharper, more refined and more capable framework with the new version.

Thanks, I think so. But I wonder what exactly have they done that achieved this effect. Do they remove some Assemblies? Do they cut any Types? Do they used a new compression format?

Did they finally remove a few of the things that have been depreciated for years?

Depreciated? ;-)

Citation required - do you have references? I don't believe /anything/ has been removed.

.NET 3.5 size is that big because it contains the x64 version of the framework in the same package. The 2.0, 3.0 packages were separated for x86 vs x64. I guess 4.0 will adopt a separated approach too. This link explains it: link

For info on the online vs offline installs for .Net 3.5, check out this blog post:http://www.hanselman.com/blog/SmallestDotNetOnTheSizeOfTheNETFramework.aspx

There was IA64 too, not only x86 and x64 version.
