Future of Linux support for reporting

What's the long-term plan for supporting Linux and Telerik Reporting? The dotnet design team is looking to remove support for System.Drawing.Common on Linux platforms. They're recommending compiler warnings in .Net 6, and full PlatformNotSupportedExceptions in .Net7

All,

Indeed, the fact that .NET 7 completely shuts down System.Drawing on non-Windows platforms puts us in a very hard situation. We have already started the research and it seems we will need to make a big architectural change in the product in order to integrate and use another drawing library. Most probably, we will go with SkiaSharp. As a time frame, I cannot promise we will be done along with the official .NET 7 release. Realistically we will target the R2 2023 release scheduled for May 2023. I will update you here when I have more details to share.

Meantime, any ideas are more than welcome. Thank you for your engagement.

Regards,
Milen

i am running the reporting code in a Linux container also.

We pass Telerik images for our reports and lack of System.Drawing.Common is going to break this in .Net 6 and going to be dead broke in .Net 7

For those unaware.. you can add this into your runtimeconfig.template.json to get Systme.Drawing.Commin working on .Net 6

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

This workaround will go away in .Net 7

We absolutely must have the ability to print images using Telerik Linux containers.

I can imagine this is a nightmare for the Progress Architects.

However, from a business standpoint this has to be in the product for us to continue using it.

As this is your dependency, I am not concerned with how you implement it.

We run all our applications in custom Linux containers on AWS just to support your reporting libraries.

This will be vital to be able to go to .NET 7.

Chiming in here,

Please see for reference -> https://docs.microsoft.com/en-us/dotnet/core/compatibility/core-libraries/6.0/system-drawing-common-windows-only

Currently, we use Telerik reporting extensively on Linux. We recently upgraded several nuget packages that caused System.Drawing.Common to be updated to file version 6.x.x. According to the article above, in order to continue to use System.Drawing.Common under .NET 6 on Linux, we needed to add a runtime switch. This did indeed fix the exception.

However, this switch is gone in .NET 7.0. Microsoft's recommendation is to use:

It's likely that Maui.Graphics is the strategic choice, given its ability as a complete cross platform library. My vote would be for Maui as a replacement, but I'll take anything as long as we can continue to use Telerik reporting on .NET 7.0.

Cheers,
Sam.

Hello Tursunkhuja,

Telerik Reporting is constantly making improvements on the rendering behavior under Linux, however, migrating to the SkiaSharp library is not in our roadmap for 2022.

Hi All,

We also have similar problem. Our project based on .net6 and we are planning to use reporting in Linux environment.

When you are planning to improve Telerik Reporting rendering behavior on Linux machines? or when you expecting to use SkiaSharp library.

 

Thank you,

Gregory

Hello Levi,

Thank you for the valuable feedback!

I just want to mention that it is possible to run Telerik Reporting on Linux even today but the library libgdiplus is required. This library is a Mono implementation of GDI+ API for non-Windows operating systems - Using Telerik Reporting in Applications on Linux Platform.

Thanks for the update. This is one I'm keenly interested in.

For reference, my use-case is with Azure Functions. Being able to host in Linux would enable us to adjust our hosting tier to much higher performance for the same cost (currently on Windows hosted). Although when I think about again, being able to fully drop the GDI dependency would also let us move to the dynamic serverless tier (which blocks most GDI access).

I understand that it's a large change and you can't give a commitment or timeline, but this feature would be huge for us - the further ability to run Telerik reports easily in more environments.

Hello Levi,

Thank you for raising awareness of those potential issues.

Our long-term plan is to try and refactor our drawing logic to utilize the SkiaSharp library.

Even if MS does not drop the support for System.Drawing.Common, the currently used library, libgdiplus, has multiple issues with text measuring, clipping, working with units other than pixels, etc. and we are researching for a solution to improve the Telerik Reporting rendering behavior on Linux machines. The SkiaSharp library may be the answer to those problems.

Please let us know if you have any other questions.

Regards,
Dimitar
