  Hello,

  What to do about this error?
  
  I know I can install “libgdiplus” on the host machine, but is this really necessary, is there anything else to do about it?

  Hello again,

  It’s probably related to the System.Drawing .NET 7 depreciation:

  Hello Nikolas,
  
  Yes, you are correct, the Syste,.Drawing.Common support has been ended for non-windows OS by MS.
  
  The detailed information can be found here:
  
  https://learn.microsoft.com/en-us/dotnet/core/compatibility/core-libraries/6.0/system-drawing-common-windows-only#reason-for-change

  So you may use the suggested workaround https://learn.microsoft.com/en-us/dotnet/core/compatibility/core-libraries/6.0/system-drawing-common-windows-only#recommended-action or install libgdi library:

  # install libgdiplus
  RUN apt-get update && apt-get install -y libgdiplus

  
  
  Hope it helps!

  Hello,

  The workaround you linked only applies to .NET 6, but we are using 7. So I will need using libgdi library, but I would also like not to install it later on.

  Hello Nikolas,
  
  Along with installing the libgdiplus library, we also need to add the file runtimeconfig.template.json to the root of the project with the following content:

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

  
  
  Please refer to the attached sample for reference:

  Hello Manish,

  That’s what we have been doing for .NET 6, but we are now running .NET 7. Please see attached image of .NET 7 MS documentation, and link if needed.

  Hello Nikolas,

  The sample shared previously is created using NET 7.0 and executed on Linux Docker and it works fine.

  It uses the JSON file along with installing the libgdiplus library. Also, the team is trying to find an alternative for the System.Drawing.Common library but we are not sure how much time it would take to complete this research and implementation.
