• Visual Studio 2008 (Pre-release) WPF and DirectX and what's possible

  I'm curious if anyone has a link detailing exactly what you can and cannot do in WPF vs DirectX. For example: If WPF is a thin wrapper over DirectX and I don't find what I'm looking for, will I be able to access the DirectX COM interface and get access to what I need and: I assume shaders aren't supported in WPF, so again, will I be able to hook up the plumbing for shaders, or will WPF have the same fate as the fixed-function pipeline (Where the shading algorithms are fixed making it difficult to create unique looking 3D.) Is 3D in WPF going to be restricted to diffuse/specular lighting Regards. MS has st ...Show All

• Visual Studio Error 1304 when installing .NET Framework 1.1

  Hi All The installation of .Net framework fails with the error 1304. "Error writing to file: Microsoft.Vsa.dll. Verify that you have access to that directory".
