This article details the settings you can use to configure Windows Presentation Framework (WPF) in .NET.
Note
.NET 6 standardizes on the prefix DOTNET_ instead of COMPlus_ for environment variables that configure .NET run-time behavior. However, the COMPlus_ prefix will continue to work. If you're using a previous version of the .NET runtime, you should still use the COMPlus_ prefix for environment variables.
Hardware acceleration in RDP
- Configures whether hardware acceleration is used for WPF apps that are accessed through Remote Desktop Protocol (RDP). Hardware acceleration refers to the use of a computer's graphics processing unit (GPU) to speed up the rendering of graphics and visual effects in an application. This can result in improved performance and more seamless, responsive graphics.
- If you omit this setting, graphics are rendered by software instead. This is equivalent to setting the value to
false.
| Setting type | Setting name | Values | Version introduced |
|---|---|---|---|
| runtimeconfig.json | Switch.System.Windows.Media.EnableHardwareAccelerationInRdp |
true - enabledfalse - disabled |
.NET 8 |
| Environment variable | N/A |
This configuration setting doesn't have a specific MSBuild property. However, you can add a RuntimeHostConfigurationOption MSBuild item instead. Use the runtimeconfig.json setting name as the value of the Include attribute. For an example, see MSBuild properties.
