此错误的任何解决方案：连接到命名管道时超时。？

Question

我无法再次打开旧表格。我收到此错误：

Timed out while connecting to named pipe

我搜索并遵循了一些步骤，但没有解决方案

• 禁用我的防火墙
• 在“Windows Forms Designer”选项中将警告级别更改为无
• 将目标 .Net 从 net8 更改为 net7
• 删除了.vs、obj、bin
• 创建新表单也会导致同样的问题

还有其他解决办法吗？我使用 VS 2022 社区

Answer 1

我将目标框架更改为

net471

，然后保存，重新加载，然后将其更改回

net8-windows

，然后保存，关闭VS并再次打开项目，现在表单正常加载了!!!
