  • Silverlight 4 JIT performance

    In the keynote Scott mentioned that SL4 has incorporated some (or all?) of the WPF JIT implementation, which translate to 30% faster startup time and also faster runtime in general due to better code optimization by the JIT engine.  This is great news, but I couldn't find any additional information about it (other than a quick mention by ...
  • Re: Pixel Shader Exception

    Yes there is another problem. Your pixel shader source is incorrect.  You need to add your .ps file into the project as a *resource*, and then refer to it as: "/myproj;component/myshader.ps"
  • Re: Pixel Shader Exception

    Replace all double 0 with 0.0, and all double 1 with 1.0. The API throws exception when the wrong type is passed in.
  • Re: Security Problems while showing OpenFileDialog

    Two things you want to make sure: (1) make sure your callback is indeed initiated from a button click.  Based on what you said this should already be the case. (2) make sure you don't set a breakpoint anywhere between the button click and the OpenFileDialog show().  If you hit a breakpoint in the debugger, it automatically ...
  • Re: Silverlight requirements

    Check this out to see what you need to download: http://www.silverlight.net/getstarted/silverlight-4-beta/If you are developing SL3 or SL4, you must use Visual Studio 2010 beta 2 or Visual Web Developer Express 2010 beta 2 (free).  If you are developing SL3 only, then VS 2008 or VWD Express 2008 (free) are fine. The rest of the requirements ...
  • Re: Apart from Isolated Storage for storing data ?

    In SL3, the easiest technique would indeed be to ask for more memory in the IsolatedStorage to store your MP3's.  This is better than having to ask the user for the MP3's using OpenFileDialog every time. In SL4, you do have the option of local file access if the files are stored the "My" directories.  But this only ...
  • Re: Is the printing just printing a bitmap?

    [quote user="mtiede@swtechnologies.com"] So has anyone seen how the printing works?  Does it just make a humongous bitmap of the screen and send that to the printer?  Or does it really just send the instructions to print elements to reduce output stream size? [/quote]  It was mentioned that SL4 printing is ...
  • Re: Re: SL4 - the end of WPF?

    I want to add that Scott Guthrie mentioned the incorporation of the full (?) WPF JIT engine into Silverlight 4, increasing the raw number crunching performance and improving SL app startup time.  I noticed the performance difference in the past, and I am quite excited about this.
  • Re: Any idea on when is it coming out?

    Silverlight 3 beta was announced in March (MIX '09), and released in July 10, for a total beta of less than 4 months.  I hope SL4 would keep up with the Mojo.  Of course, this was a blessing rather than something to be taken for granted, so I wouldn't be extremely disappointed if the final SL4 is released in April or May (but ...
  • Re: Any idea on when is it coming out?

    Definitely first half of 2010.  My guess is March (MIX '10).
