Since you specifically requested , you must configure your project correctly. If you leave the setting on "Any CPU", it might crash if the system tries to load 32-bit dependencies alongside your 64-bit SlimDX.

The is a 64-bit software library that acts as a managed wrapper for Microsoft DirectX . It allows developers to build high-performance graphics and multimedia applications using .NET languages like C# and VB.NET, and provides the necessary files for end-users to run those applications. 1. Key Components and Features

SlimDX was an open-source wrapper that allowed .NET developers (C#, VB.NET) to call native DirectX APIs (Direct3D, DirectInput, DirectSound, XAudio2, etc.) without writing complex COM interop code.

Specifically designed for 64-bit (x64) Windows systems, typically ensuring better performance and memory handling for modern DirectX applications.
