但是还是报错.

但自包含的包工作正常.

解决方案

这种情况是由于您的另一台计算机可能没有运行 .NET 5.0 WPF 应用所需的 .NET 5.0.7 桌面运行时.

在

该图显示您在安装 .NET 5.0.7 运行时后仍需手动安装 .NET 5.0.7 桌面运行时.

因此，要解决您的问题，您必须安装 .NET 5.0.7 Desktop Runtime，而不仅仅是安装 .NET 5.0.7 Runtime.

Hi I create one WPF application using .Net 5.0 . It is working fine in my dev system .

But when i try to copy and run bin folder to my windows 7 system , It is giving below error :

The framework 'Microsoft.WindowsDesktop.App', version '5.0.0' was not found.

But still getting error .

Update :

But Self contained package working fine .

解决方案

This condition is caused by the fact that your other machine may not have the required .NET 5.0.7 Desktop runtime to run your .NET 5.0 WPF app.

On the official page to download .NET 5.0, each SDK and related runtime version has its own notes. If you only install .NET 5.0 runtime, it won't install the related .NET 5.0 Desktop runtime to support WPF and Windows Forms.

For example:

That picture shows that you still have to install .NET 5.0.7 Desktop Runtime manually after you install .NET 5.0.7 runtime.

Therefore to fix your problem, you have to install .NET 5.0.7 Desktop Runtime, not just installing .NET 5.0.7 Runtime.
