Microsoft .NET Framework 4.0 RC and Visual Studio 2010 RC Available Now
Feedback on VS2010 RC has been great, and we hope you agree. Feel free to provide feedback about your installation and development experience. Performance was a major focus for the RC from Beta 2 feedback and the changes are phenomenal.
Another tremendous effort went into making .NET 4.0 deployment more manageable for our developers. The full installation for .NET 4.0 RC – for both x86 and x64 combined – is only 48 MB compared to .NET 3.5 SP1 at 231 MB.
If you are having problems installing .NET 4.0 or Visual Studio 2010, please visit our support forums.
You may find solutions to common problems right away, or the community – including Microsoft employees – will be glad to assist you. If you are having installation problems, please download and run the log collection utility. This creates a vslogs.cab file in your %TEMP% directory that you can upload and paste the link in any correspondence. If you need file hosting space, consider using Windows Live SkyDrive.
