Program crashes when using Managed DirectX with .Net Framework 4.0

Question

We are having a problem using DirectSound with the Managed DirectX dlls and the .Net Framework 4.0

The program works fine with .Net Framework 2.0 - but we have a requirement to upgrade to 4.0 to use some other components.

When the program invokes the Sound module, it crashes with the exception noted below.

Anybody seen this one and know how to fix it?

I know this is a late reply but for me to get this working I had to find two DirectX DLL Microsoft.DirectX and Microsoft.DirectX.DirectInput and add then as a reference to the project.

Then just use the DirectX namespace for calling methods.

This was eventually answered by a Microsoft employee from the DirectX team. The answer was: – Mike Aug 08 '13 at 20:11

 <!--  Uncomment this section when switching from Net2.0 to Net 4.0 
  It is intended to fix problems loading DirectX dlls  - per Microsoft-->

 <!-- 

  <startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0"/>

   </startup>

Officially the legacy DirectX Managed 1.1 assemblies do not support .NET 4.0. See this blog post for details.

You could look at using SlimDX or some other alternative...
