How to resolve the image not rendered issue in .NET 6.0 on Linux Environment

After the release of .NET 6, the Bold Reports^® Report Viewer component stopped rendering images on non-Windows platforms due to a breaking change that restricted the use of the System.Drawing.Common library to Windows only. This causes issues for developers using the component on Linux and other non-Windows platforms. This article explores an alternative solution that enables the Report Viewer to render images on Linux and other non-Windows platforms.

The breaking change in .NET 6 means any applications using the System.Drawing.Common library will not work on Linux, Mac, and other non-Windows platforms. This causes the Report Viewer component to stop rendering images on Linux and other non-Windows platforms.

However, there is a way to enable the Report Viewer to render images on Linux and other non-Windows platforms. Do this by setting the System.Drawing.EnableUnixSupport runtime configuration switch to true in the runtimeconfig.json file. To enable this flag, follow these steps:

1. Add the runtimeconfig.template.json file to your application.

2. Add the following configuration properties to the runtimeconfig.template.json file.

{

  "configProperties": {

    "System.Drawing.EnableUnixSupport": true

  }

}

By enabling the System.Drawing.EnableUnixSupport flag, and the Report Viewer will start rendering images on non-Windows platforms like Linux, Mac, and Kubernetes.
