Code sample broken

I get:

Error 1 The tag 'CoreSmoothStreamingMediaElement' does not exist in XML namespace 'clr-namespace:Microsoft.SilverlightMediaFramework.Player;assembly=Microsoft.SilverlightMediaFramework.Player'. C:\Project\SilverLight\SmfSimplePlayer\MainPage.xaml 12 14 SmfSimplePlayer

Downloaded latest IIS Smooth SDK per instructions, does not compile.

I was having this same issue.  The problem lies in the fact that the version of Microsoft.Web.Media.SmoothStreaming that you reference in your project differs from the one that SMF was compiled against.  What I did was just recompile the source for Microsoft.SilverlightMediaFramework.Player against the version that I was attempting to use.  Updated my project with the new dll and it worked fine.

The current build of SMF is targeting the SmoothStreamingMediaElement Beta 2 build.  Download links can be found on the front page.

I have just download and try to get the following build errors

for the SMF project

Error 1 Operator '==' cannot be applied to operands of type 'Microsoft.Web.Media.SmoothStreaming.SmoothStreamingMediaElementState' and 'System.Windows.Media.MediaElementState' C:\Users\joe\Documents\Visual Studio 2008\Microsoft.SilverlightMediaFramework\Microsoft.SilverlightMediaFramework.Player\CoreSmoothStreamingMediaElement.cs 323 9 Microsoft.SilverlightMediaFramework.Player

What is wrong?

Eventually complied using the dll's from the source code and not the ones from the download page.

Yes, this is what I had to do as well.  Please ignore all the comments above on how you need to download the right binaries, they are incorrect.  You have to build everything yourself or it will not work.
