.net 3.0

“Marketing messed it up. Again.”

.net 3.0 – ny funksjonalitet på .net 2.0

Q: What is the .NET Framework 3.0 (formerly WinFX)?

A: The .NET Framework 3.0 is Microsoft's managed code programming model. It is a superset of the .NET Framework 2.0, combining .NET Framework 2.0 components with new technologies

Q: How does the .NET Framework 3.0 relate to the .NET Framework 2.0?

A: The .NET Framework 3.0 is an additive release to the .NET Framework 2.0. There are no changes to the version of the .NET Framework 2.0 components included in the .NET Framework 3.0.

Q: Do I need to do any application compatibility testing for my .NET Framework 2.0 applications?

A: You don’t need to do any additional testing for your .NET Framework 2.0 applications when you install the .NET Framework 3.0.

Kampanje for å endre navnet tilbake

To:  Microsoft Dear Jason Zander and whom ever it may concern,

WinFX was renamed to .NET 3.0. This decision was made without any community feedback, which is uncharacteristic of Microsoft’s recent openness to community input.

Not only is “.NET 3.0” a misnomer, it throws a wrench in the .NET Framework, likely jamming future versions. It is also a severe inconvenience to developers, especially newcomers.

We ask that this short-sighted decision be turned around before the first release of the framework for its own sake as well as the sake of developers.

I state eight reasons to revert to the old name of WinFX. The terminology used here assumes that you’ve read Jason’s blog entry here: http://blogs.msdn.com/jasonz/archive/2006/06/13/630066.aspxKilde: http://www.petitiononline.com/mod_perl/signed.cgi?winfx 952 signert pr. 10.04.07

Copy slides

Use this type of template for your standard copy slides.

Use the design templates to apply any combination of colour and icon to a copy slide.

As shown here, the colour and icons at the top of the copy slide should match the colour and icons of the most recent section header slide.

The colour of the headings should match the colour at the top of the copy slide (and the most recent section header slide).

Note all sub-headings are sentence case, e.g. “The cat on the mat”.
