We’re still waiting for Microsoft to release the visual studio windows forms designer for .net core. It is currently only in preview stage and supports only the basic use cases. 

We are waiting for Microsoft to complete that because we believe that being able to design windows forms is critical for desktop applications

Hi Noam, do you see a chance to compile Firefly.Box.dll in .net 7. I am asking this because we are thinking about converting our application to .net 7 and we need your support in this matter.

Hi Maciej,

The migrated code and the ENV and Friefly source code are highly compatible with .NET core > 98% according to analysis tools.

Because Microsoft Visual Studio has not yet completed its work on a Visual Form Designer for .NET core - we did not complete the adjustment to .NET Core, since we don't believe anyone will buy a migration to .NET without a Visual Form Designer.

Since you have all the source code, you can perform the move to .NET Core yourself - one of our customers did that a few months ago and although it required some work, they seem to be happy about it - Maybe they can respond to this forum post.

As for the Visual Designer, the best advice I have at this point is to use two project files, for the same C# files.

One with .NET Framework - to use with the visual designer, and one with .NET Core to compile and use .NET Core 7.

Since we haven't done a .NET Core migration ourselves I don't have a lot more information to give you - other than that one of our customers has done it and as far as I know succeeded.

I recommend that you either postpone until we've done it or try to do it with the source code you have - contracting us to help is also an option, but it'll be with a significant cost

Hi Noam,

We’ve migrated to the .NET 8 platform, but the Form Designer doesn’t fully work with Firefly controls. 
For example, data binding features and the table wizard aren’t available. We can work around this, but only by writing code directly.

Do you have an migrated version of the Firefly libraries that fully supports the Form Designer?

Hi Maciej,

Microsoft's .NET Core visual designer isn't compatible with the way it worked in .NET Framework - which required significant R&D and code changes - we've implemented that as part of our .NET Core offering - reach out to David on our team to enquire about the commercial terms of getting that latest version of the source code.
