Is it possible to use TeeChart v4 Pro in WinForms application (.NET Core 3 preview)

Hello.
I'm using
Visual Studio 2019 Pro (16.0.2) and
.NET Core 3 SDK Preview 4.
I've create application from a
Windows Forms App (.NET Core) template and added
Steema.TeeChart.NET nuget package to my project (4.2019.3.15).
After that I've created Steema.TeeChart.Chart variable (because there is no Steema.TeeChart.
TChart class in assembly I've referenced).
But it has less properties than Steema.TeeChart.
TChart that I was using before for .NET 4.0 (for example
Dock property is missing).
Moreover I cannot simply use
this.Controls.Add(this.tChart1):
Code: Select all
cannot convert from 'Steema.TeeChart.Chart' to 'System.Windows.Forms.Control'
So is it possible to use TeeChart in WinForms application (.NET Core 3 preview 4)? If not - when are you planning begin?
According to latest news from Microsoft upcoming .NET Framework 4.8 will have less features than .NET Core 3 (it will support .NET Standart 2.1) - so we are looking for retargeting our new Windows Forms projects to the most modern platform.
Thank you.

Hello,
We are preparing the existing TeeChart version for tests in the Net Core 3 Framework. We expect to be able to make a test version available soon. In the meantime, the current TeeChart NetStandard version can be used as a non-forms control - please find following an example of the use of TeeChart.NET Standard in an ASP.NET Core app:

Unfortunatelly ASP.NET Core app is not an option for us. Our software is fully desktop.
So we will wait for an updated version.

Any progress for now? Is there a new version to test?

Not at the moment, no. As far as we understand from this blog post
here, the roadmap for .NET Core/.NET looks like this:

We here at Steema Software are committed to complying with this timeline, and will have versions of TeeChart.NET ready for the Release Candidate of .NET Core 3.0 due in July 2019. We will be in touch with you personally as soon as we have a version of TeeChart.NET for .NET Core 3.0 which we feel is ready for client testing.

Hello,
Just as a footnote to Chris' official timeline. We are optimistic that we can have a version available for use, via Nuget, before mid June.
Regards,
Marc Meumann

We've created a test NuGet package for .NET Core 3.0 preview 5 Windows Forms which you can download from
here. You will be able to install this NuGet package into your version of Visual Studio by copying it to a local NuGet package source:

Do please let us know how your tests go.

I've performed a quick test - everything is going fine for now..
It's really hard to work without WinForms designer in .NET Core - expecting VS team to add it soon. After that I'll be able to peform full testing.
Thank you for your job.

You're very welcome. Just to let you know that we've added six new NuGet packages here:
https://www.nuget.org/profiles/steema
These are TeeChart for .NET Core 3.0 Pro/Business for .Net Core 3.0, .Net Core 3.0 Windows Forms and .Net Core 3.0 WPF.

Hello again.
Latest Visual Strudio 2019 still not have WinForms designer in .NET Core
, so I've performed a deeper test:
- Downloaded TeeChart.Winform (https://www.nuget.org/packages/Steema.T ... e.WinForm/)
- Installed .NET Core preview 6 (because .NET Core preview 7 only works with Visual Studio 2019 16.3 preview 1)
- Ported one of my current production WinForm app to .NET Core 3 (only application code, all dependency libraries (except for TeeChart) are still on .NET Framework 4.0) with lastest Visual Studio 2019 16.2
My existing
licenses.licx (Build Action: Embedded resource) was:
Code: Select all
Steema.TeeChart.TChart, TeeChart, Version=4.2018.12.17, Culture=neutral, PublicKeyToken=9c8126276c77bdb7
and I've changed it to:
Code: Select all
Steema.TeeChart.TChart, TeeChart.WinForm, Version=4.2019.6.4, Culture=neutral, PublicKeyToken=ab44c04939770ee2
But I get a compilation error:
LC0000: Could not load file or assembly 'System.Runtime, Version=4.2.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (HRESULT: 0x80131058)
If I remove
licenses.licx from my .NET Core app - all charts have evaluation watermarks.
What's wrong with my code?
P.S. Except for this - everything is working fine for now.

The licenses.licx is unnecessary for TeeChart.NET Core as this file is only relevant to the Windows Forms designer and the Web Forms designer - in TeeChart.NET Core you can delete it.
Are you using your TeeChart.licenses file? It is this file that will remove the watermark.

In near future, when WinForms designer will be added to Visual Studio 2019, whether it will be necessary to add this file?

Yes (Build Action: Embedded resource). It is
exactly the same file that I use in project targeting .NET Framework 4.0. Do I need to generate different one somehow?
P. S. Just created simple WinForms app (.NET Framework) and added TeeChart.licenses (Build Action: Embedded resource) - no watermark.
Created WinForms app (.NET Core), added all files from previous app (changed namespace of course), changed TeeChart.dll to TeeChart.WinForm.dll and added
the same TeeChart.licenses (Build Action: Embedded resource) - watermark is present.
Looks like I'm doing something wrong..

I don't know. If the WinForm .NETCore designer has identical functionality to the WinForm .NET designer then this file may be necessary. We will have to wait to see.

Try putting your license into the following page:
https://www.steema.com/linkIn/License_information_check
This is what I get with a dummy license:
- Screenshot from 2019-08-09 09-25-08.png (32.92 KiB) Viewed 34331 times
This license will not work with Steema.TeeChart.NETCore.WinForm 4.2019.6.4 (note the license is valid by two days) because the 'Assembly name' of 'teechart.winform' is not listed. If your license does not have 'teechart.winform' listed it won't work either. Obtaining a new TeeChart.licenses file with 'teechart.winform' listed is easy to do by requesting one from
sales@steema.com with your license details.

Hello,
Please note. We are resending the license file that we sent to you earlier as previous one wasn't correctly prepared for teechart.winform support. Now modded.
Sorry for the inconvenience.

Marc
