Cuál CTP de .Net 3.0 debo de usar?

Para los que comienzamos con .Net Framwork 3.0, y como se sabe recientemente se han liberado diferentes releases de esta versión, la última es el CTP de Julio pero antes de instalarlo en su equipo PC, se debe de tomar en consideración que es lo que se soporta en cada nuevo release liberado.

La versión de CTP Julio tiene nuevas caracateristicas para Windows Workflow Foundation y Space Cards, pero se disminuye la parte del soporte de Windows Presentation Foundation. Por lo tanto surge la pregunta: Qué versión debo de instalar?

En el blog de Tom Archer, se indican algunos tips importantes al momento de seleccionar la versión de .Net Framework 3.0 que se acomode a las necesidades del desarrollador:

• If you want to run (not develop .NET 3.0 applications), you only need the .NET 3.0 Runtime Components for the desired build milestone. (The other downloads are for developing native and .NET 3.0 applications)
• If you want to develop native-only (non.NET) applications, you only need the Windows SDK for the desired build milestone.
• "Orcas" Tools for .NET 3.0 Development is only needed if you are writing Windows Presentation Foundation applications and are using a released (non beta) copy of Visual Studio 2005 (including the Express Editions)
• Windows Workflow Foundation (WF) Extensions to Visual Studio is only needed if you are writing Windows Workflow Foundation applications and are using a released (non beta) copy of Visual Studio 2005 (including the Express Editions)

Note: Since these are all "prerelease bits", it is highly recommended that you install these products/technologies on a non-production, test machine and remove any previous versions before installing.

Build Notes

Here are some key notes for each currently published build milestone for Windows Vista and the .NET 3.0 Framework development tools.

July 2006 CTP

• Windows Vista July CTP (5472.5) is only available for MSDN subscribers and beta members
• The July CTP includes builds of the .NET Framework 3.0 Runtime Components and Windows SDK for use with Windows Vista July CTP (5472.5), Windows XP or Windows 2003 Server
• There is no July CTP build of the “Orcas” Development Tools for the .NET Framework 3.0
• The July CTP builds of .NET Framework 3.0 Runtime Components and Windows SDK are not supported for .NET 3.0 development on Windows Vista Beta 2 or Windows Vista June CTP

June 2006 CTP

• Windows Vista June CTP (5456) is only available to beta members
• There are public downloads for June CTP builds of .NET Framework 3.0 Runtime Components, Windows SDK and “Orcas” Development Tools for the .NET Framework 3.0 for use with Windows Vista June CTP (5456), Windows XP or Windows 2003 Server
• The June CTP builds of .NET Framework 3.0 Runtime Components, Windows SDK and “Orcas” Development Tools for the .NET Framework 3.0 are not supported for .NET Framework 3.0 development on Windows Vista Beta 2

Beta 2

• Windows Vista Beta 2 (Build 5384) is the most current public build of the Vista operating system that is available to anyone.
• There are matching bits for the .NET Framework 3.0 Runtime Components, Windows SDK, “Orcas” Development Tools for the .NET Framework 3.0 and the Visual Studio 2005 Extensions for Windows Workflow Foundation bits that are also publicly available.
• If this is the most current version of Windows Vista that you can access (the June CTP requires beta membership and the July CTP requires beta membership or an MSDN subscription), then you should only use the matching Beta 2 bits for the aforementioned runtime components and development tools.

Asi tomen muy en cuanta que es lo que quieren implementar, e mi caso yo estoy enfocado a WWF por lo cual opte por el CTP de Julio, pero para lo que les guste WPF les recomiendo instalar el CTP de Junio.
