System.Drawing.Common Alternatives (.NET 7 & Non-Windows)

On non-Windows operating systems, a TypeInitializationException is thrown with a PlatformNotSupportedException as the inner exception. The platform analyzer emits compile-time warnings for non-Windows platforms. The following runtime exception is thrown unless you set a configuration option:

System.TypeInitializationException : The type initializer for 'Gdip' threw an exception.

    ---- System.PlatformNotSupportedException : System.Drawing.Common is not supported on non-Windows platforms.

Temporary work-around in .NET 6:

Enable support for non-Windows platforms by setting the System.Drawing.EnableUnixSupport runtime configuration switch to true in the runtimeconfig.json file:

{
    "runtimeOptions": {
        "configProperties": {
            "System.Drawing.EnableUnixSupport": true
        }
    }
}

Additionally, add the following line at the beginning of your code to enable the configuration programmatically:

// Enable System.Drawing.Common support on non-Windows platforms in .NET 6
System.AppContext.SetSwitch("System.Drawing.EnableUnixSupport", true);

// Enable System.Drawing.Common support on non-Windows platforms in .NET 6
System.AppContext.SetSwitch("System.Drawing.EnableUnixSupport", true);

' Enable System.Drawing.Common support on non-Windows platforms in .NET 6
System.AppContext.SetSwitch("System.Drawing.EnableUnixSupport", True)
