Hi,
Whenever you go to online help by clicking "F1" for a specific Silverlight API in the Visual Studio 2008, you will end up seeing a Silverlight3 Beta content. This can be clearly identified by the following two aspects.
1. Under the search topic, you will see the following lines
[Note: This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]
2. Check the "URL:" combo, it contains the URL path ending with **VS96.aspx.
For eg., when you click F1 for "Projection" property, it will go to the online help page with the topic "UIElement..::.Projection Property". Under this topic you will notice that "[Note: This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]" is displayed. Also in the URL path, http://msdn.microsoft.com/en-us/library/system.windows.uielement.projection(VS.96).aspx is mentioned.
These are the clear indications that you are seeing the old content.
Workaround:
There is a workaround available to see the correct content. Just expand the "F1 Options:" combo box, you will see two topics with the same name or with some suffix attached to it. For eg., in this "Projection" help case you will see "Projection Property" and "Project Property (2)". On clicking "Projection Property (2)" you will get the latest content. This can be verified by above mentioned check.
1. You will not see the "Note" message as mentioned above.
2. Check the URL path, it will end with VS95.aspx.
Warning:
Please don't generalise the above mentioned workaround for all the Silverlight related topics. Sometimes you will get to see more than 10 topics in the F1 options combo box and it is difficult to find the latest topic(you have to check manually). And for some topics, you might get the latest topic itself as it might not have changes since Beta release. Please ensure this at your own discretion.
This problem is applicable for Online help (F1) only.
cheers,
Saran.
