问题
I've installed .net 4.0 as well as XNA 4.0 . A while ago I used Microsoft.DirectX to play some music and now when I try to redo the work, I can't find the reference. Did the new changes on the platform modify or moved something in the references?
回答1:
Visual Studio 2010:
right click on project
Menu select "Add reference..."
select tab "Browse"
select directory "C:\windows\assembly\ GAC\Microsoft.DirectX.AudioVideoPlayback
The DLL to reference is in that folder.
You will need to download and install the DirectX Software Development Kit first, if you haven't done so already.
