Hi Michael,

Currently, we only support the standard .NET framework. We do not have a confirmed schedule on when we will port ChartDirector to the .NET Core framework.

When you say "standard" you mean  .net framework and NOT .net standard?

Because that's what you should be targetting for future versions, .NET standard which will work with framework and core.

Regards,

Keith

Hi Keith,

From my understanding, the .NET standard is a very limited subset of the .NET framework and .NET Core. In particular, it does not support any user interface. That's why for real applications, we need .NET Core or .NET Framework or Universal Windows Platform, which are built on-top of the .NET standard.

The .NET standard is useful for "libraries" that do not have user interface or use any features specific to .NET Framework, .NET Core or other implementation. An example is a library for sorting numbers or for numerical integration.

Unluckily, ChartDirector does have "controls" and user interface support, such as clickable hot spots, programmable track cursors, drag to zoom/scroll, viewport control, etc.. This makes it impossible to target the .NET standard alone.

.net standard has no UI, but it does have drawing.  For your web offering it would be nice to have a .net standard version that is cross platform.

Hi Keith,

We have investigated .NET standard in the past. At that time, we found that there is no graphics capabilities.

I just looked at the latest .NET Standard 2.0, but I cannot find any graphics capability.

I found a System.Drawing namespace, which supports a very small subset of the "data structures" for drawing. For example, it has a class for Color, and one for Point (which is just two numbers for the x and y coordinates), and one for Rectangle (which is just 4 points). It cannot actually draw any of them. Drawing requires an object that can draw things, such as the "System.Drawing.Graphics" object, and also something to draw onto, such as a "System.Drawing.Bitmap" object. But these things do not seem to be available even in the latest version of the .NET Standard.

Hi Peter,

Any changes to this with .NET Core 3.0? .NET Core 3.0 is going to include support for WinForm and WPF and there are suggestions that the graphics namespace would also contain new items.

Hi Erkki,

The .NET Core 3.0 still have not been official release by Microsoft. (There is only a "Preview" available.) So we have not yet tested ChartDirector with .NET Core 3.0 yet.

When .NET Core 3.0 is official released, we will try to compile ChartDirector with the target set to .NET Core 3.0. I suspect there will still be some unsupported .NET API. We will then see if we can redesign the code to not using those unsupported API.

Regards
Peter Kwan

Hi Peter,

Any updated on this? .NET Core 3.0 has been officially released.
We are looking into possible ways to upgrade our system to .NET Core and the graph component is a big part of it.

Regards

Robert

We are really interested in this as well, given that "Framework" is a dead end, we will be porting to .NET core during 2020.

Keith

Hi Robert/Keith,

Yes, we are right now porting ChartDirector to .NET Core. The desktop part that supports Windows Forms and WPF are almost complete. It is completely compatible with the .NET Framework, which means your code do not need to change when porting to .NET Core. All our sample code continues to run normally.

For the web part, because ASP.NET Core itself is not compatible with ASP.NET or ASP.NET MVC, so it takes more effort to port. In addition to porting ChartDirector (which we have already completed), we also need to port all of our sample code.

Are you using ChartDirector for desktop or web applications? If you are using it for desktop application, we may be able to get a ChartDirector for .NET Core to you in the next week, knowing that you just need to replace the old DLL with the new DLL and keep using your existing code and existing ChartDirector documentation.

If you are using ChartDirector for web applications, it might take longer (may in Dec 2019) as we will need to port hundreds of our sample code and update our documentation.

Regards
Peter Kwan

I'm using ChartDirector in a WebApi to generate bitmap images to return to the browser.  I think I would just need the "Desktop" dll.  I would love to get my hands on a pre-release version as the rest of my api is .net core.

Hi Peter,

That's great news! Thanks for the update.
We are using ChardDirector for web apps at the moment.
Looking forward to the .Net Core update.

Regards

Robert

Hi Peter,

Do you have an update on support for .Net Core?

Kind regards,
Terry

Hi Terry,

The following contains the release candidate of for "ChartDirector for .NET Core" DLLs. It contains two DLLs. If you just need to create chart images, you just need "ChartDirector.Net.Core.dll". If you need to use the ChartDirector desktop controls (the Windows Forms or WPF controls), then you also need "ChartDirector.Net.Core.Controls.dll".

As far as I know, the API for generating chart images and the controls are compatible with the current ChartDirector for .NET Framework. That means existing code do not need to change.

https://www.advsofteng.com/support/netchartdir.core.640rc1.zip

The "ChartDirector.Net.Core.dll" requires "System.Drawing.Common 4.5" or above. The .NET Core 3 includes "System.Drawing.Common". However, depending on your project type, Visual Studio may not automatically include it in the project. From our testing, Visual Studio will include it in Windows Forms projects, but not WPF. If it is a WPF project, you would have to manually add the line "<UseWindowsForms>true</UseWindowsForms>" to the project file, or to use nuget to get the "System.Drawing.Common" package into the project.

In the real release, we will likely release the DLLs as a nuget package, so Visual Studio can automatically include the "System.Drawing.Common" in the project.

Regards
Peter Kwan

Thank you Peter...

It is now working great in my .Net Core application with no code changes.
