It doesn't repro on my side, after reloading the project, then everything work well

kirsan31 · 2024-10-10T10:10:39Z

@LeafShi1 this is not my repro app on the screen.

Designer fail to load only with:
<TargetFrameworks>net8.0-windows;net7.0-windows</TargetFrameworks>
<TargetFrameworks>net9.0-windows;net7.0-windows</TargetFrameworks>

And this issue related to the version of the package WinForms.DataVisualization, if update the version to 1.7.0, the Designer can be loaded normally.

This problem has occurred since version 1.9.2, @kirsan31 you can consider using 1.9.1 in your project

kirsan31 · 2024-10-11T07:43:18Z

@LeafShi1

And this issue related to the version of the package WinForms.DataVisualization
This problem has occurred since version 1.9.2

Nice catch - thank you! 🙏

I am a maintainer of WinForms.DataVisualization. Main change in 1.9.2 was adding net8.0-windows tfm to package, other changes are small fixes not related to designer. But just in case I checked 1.9.2 without net8.0-windows support - no problem.

We have:

If package support only net7.0-windows and net6.0-windows - all work fine on client with all configurations.
If package support net7.0-windows and net6.0-windows and net8.0-windows (or net7.0-windows and net8.0-windows):
2.1 If client uses single tfm net8.0-windows - all work fine. So net8.0-windows support in package works correctly.
2.2 If client uses multiple tfms but main (first) not .Net8 - all work fine.
2.3 The problem only if client uses multiple tfms and main (first) is .Net8.

So the bug appears only if package support multiple tfms including net8.0-windows and client uses multiple tfms with main (first) is net8.0-windows.
More of it I've created a small repro project as possible (updated it at 1 post) - simple new empty (no controls on the form) winforms project with <TargetFrameworks>net8.0-windows;net7.0-windows</TargetFrameworks> and

<ItemGroup>
   <PackageReference Include="WinForms.DataVisualization" Version="1.9.2" /> 
</ItemGroup>

And designer fail to load with the same error. So I think we have here some sort of very interesting bug 🤔
The error : Could not load type 'System.Runtime.CompilerServices.NullableContextAttribute' from assembly 'System.Runtime, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. and the fact that NullableContextAttribute was introduced at .Net8 suggests that with multiple tfms the designer is trying to get this type from the wrong dll...

P.s. I've tried to build package with updated Microsoft.WinForms.Designer.SDK 1.6.0 version - not helped.

@Tanya-Solyanik @merriemcgaw This issue also related to multitarget, should we investigate further?

Tanya-Solyanik · 2024-10-14T19:48:58Z

Yes, please. Search the designer repo issues to see if we have a duplicate please.

LeafShi1 · 2024-10-15T09:57:46Z

Yes, please. Search the designer repo issues to see if we have a duplicate please.

There are 2 multi target issues in designer repo, but they are not the same
Created a new bug in Designer repo https://github.com/microsoft/winforms-designer/issues/6125

To make sure I've got the right of it - what we're seeing is that if we're targeting net8.0-windows first of multiple tfms and reference the DataVis 1.9.2 component we have the problem. Otherwise, we're seeing generally the right behavior?

I can't be 100% sure, but most likely it sounds like this:

If we're targeting net8.0-windows first of multiple tfms and reference the user component that support multiple tfms and out of process designer - we have the problem. Otherwise, we're seeing generally the right behavior.

In this case designer tring to load wrong dependencys : NullableContextAttribute version 7, but it was introduced only in .Net8.

So the problem not in .net8, we just caught this bug on net8 because earlier versions didn't have the NullableContextAttribute and we crashed.

Great explanation @kirsan31 thanks!

merriemcgaw · 2024-11-12T19:55:28Z

I'm going to go ahead and close this since we've got an internal issue tracking it now. @kirsan31 we'll reach out or reply on this issue when we have an update. I'm creating an internal item to review multi-targeting in general to do a deep dive and make sure we support as much as we can.
