Red-bit and Green-bit Assemblies

Re-bit and Green-bit assemblies

Visual Studio 2008 and 2010 targets/supports various .NET Framework versions installed and that could have been achieved by installing one .NET Framework version on the top of another version. For example, .NET 3.0 installed on .NET 2.0, and then .NET 3.5 on .NET 3.0 and .NET 4.0 on .NET 3.5.

The .NET 3.5 Framework version holds green bit assemblies which are additional assemblies and can be installed at the top of other existing .NET Framework assemblies.

Green bit assemblies when installed, these don't affect existing assemblies. For example, .NET 3.0 when installed on .NET 2.0, it does not affect .NET 2.0 assemblies.

In the similar manner .NET 3.5 assemblies does not affect the framework version either 2.0 or 3.0 on the top of which you will be installing it.

Whereas Red bit assemblies are the assemblies which ship either as part of the platform or part of a development tool. For example, Windows Vista ships WPF, WCF etc, and Visual Studio 2005 ships .NET 2.0. Besides assemblies delivered as service packs, hot fixes or updates are also considered as Red bit assemblies.As Orcas targets/supports various .NET Framework versions installed and that could have been achieved by installing one .NET Framework version on the top of another version.
