And repeated this error message many times

Could you provide a more detailed way to reproduce the issue, e.g. an example notebook?

Based on the way the error message begins, it looks like there might be a path that needs to be quoted, that was broken in two by the space in Program Files.

if not use '#!pwsh dotnet build xxx.dll'command in 'net interactive notebooks' but use dotnet build xxx.dll in vscode pwsh terminal,the problem is still appear， when at least second time after update source code, change some place in the source code. at pwsh terminal and use command 'dotnet ... xxx.dll' then appear this problem,

I try to reproduce the error process as follows: 1，create or open some *.ipynb file in vscode use '.net interactive notbooks' plugin 2, #r "local_xxx.dll" // this dll is local machine not from nuget source,ok. 3, use some test sentence like is "xx.some_property" and press key : ctrl+enter ,then show correct results! 4, find the xxx.dll source code ,change some place ,for example , change property name from xx.some_property update to xx.some_property111, and save and excute command 'dotnet build ... xxx.dll' in vscode terminal , and this time will recived many time wram message say meanings'.... File locked by ". NET Host (14556)" ...'

It sounds like the dotnet-interactive process is holding onto the .dll and preventing the build from overwriting it. In VS Code, if you restart the kernel, it should allow you to rebuild the project. You can do this by opening the command palette and running the command .NET Interactive: Restart the current notebook's kernel. You'll need to rerun the notebook cells afterward.

[nczsl]

yes, but not very easy to use.

Is restarting the Kernel between every update the way to go when developing extensions? In that case, are there any ways to restart the kernel programatically from a cell?

[jonsequitur]

There's no way to programmatically restart the kernel.
