IronBarcode - System.Drawing.Common in .NET6

Starting with .NET 6, System.Drawing.Common will only work on Windows.

  • On non-Windows operating systems, unless you set a runtime configuration switch, a TypeInitializationException exception is thrown with PlatformNotSupportedException as the inner exception.
  • In .NET 6, the platform analyzer emits compile-time warnings when referencing code is compiled for non-Windows operating systems. In addition, the following run-time 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. See https://aka.ms/systemdrawingnonwindows for more information.

Temporary work-around: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
        }
     }
  }
