Build failed when the DesignTools assemblies are loaded by Visual Studio.

[benZhai01]

I'm sorry that I can't find a correct place to report the issues of xaml design time. if any suggestions, please let me know☺.

Environment:

Microsoft Visual Studio Enterprise 2019 Preview
Version 16.4.0 Preview 5.0

Issuse:

After opening the MainWindow.xaml in DemoApplication project(building the entire solution successfully before, so I think the DesignTools is loaded by VS), then I modify some code in CustomControlLibrary.WpfCore.DesignTools project and want to re-build it, but failed.

Is there any way to improve this? because it's really a nightmare during developing the XAML design time.

VS loads assembly and it gets locked on disk so we get build errors. Workaround is to close VS instance and open it again then build should work.

Yeah, that's a workaround, but it's weird and really inconvenient to me, can we have another better option? it's impossible?
Seems the old architecture won't have the problem, the new one should not at least be worse than the old one, right?

Any updates?

I spent almost half of the time to restart VS when developing desgin time assemblies. Can anyone address it?

We will investigate this and update you, currently I am reopening this issue. Thanks

Can I release the occupation of the corresponding designtool.dll when the view is closed?
