I want to know how do you want me to do it I see some ways: I can copy my code in other directory and change references to Compact Framework. As a result I'll have two copies of my code. It's the worst alternative, isn't it I can use only Compact Framework even on PC (if it's possible); Something else What is t

      • I caught some people quoting managed performance loss at only 2% (over unmanaged). I am just curious how accurate that assessment is. Last time I was looking into it, DX programmers were quoting 90% of managed performance as a BEST case scenario. (usually much lower) If the margin has grown so low, is there any large scale games developed using C#

I read the XNA FAQ, and it sounds to me like they've already deprecated Managed DirectX... does that mean that XNA has/will entirely replace DirectX If I want to write a program using DirectX in .NET, would this then mean that my program will need to

      • The matter is like this. If someone is developing the application, say, new programming language, based on MDX\XNA using .Net Framework CodeDom classes, there is no problem with MDX, due to all MDX libraries has included in .Net Framework. In the XNA case to build an application user must prior install the full XNA GSE, because distributing of its DLLs with an application is not permitted (as lice

If the origin is at the bottom right of the screen, I want the nose of my spaceship pointing towards the right, the top pointing up, and the right wing pointing towards you. My understanding of XNA is that its coordinate system is right handed. Thus, the origin is at the bottom right of your scree
