Winforms app missing files in Solution Explorer

Question

When I try to create a windows forms app in C# in visual studio and the project opens, I don't
find any files in the Solution Explorer.

I doubted that something wrong happened when installing Visual Studio, so I reinstalled my Windows operating system and then visual studio, but the problem still exists.

I searched a lot but didn't find similar problems like this. I attached some helpful screenshots that also include the installed components.

Thanks in advance to those who will help me.

At first, I tried to reinstall visual studio, then I reinstalled my Windows operating system and then visual studio, but the problem still exists.

Answer 1

Normally, the dotnet environment variable is automatically added when Visual Studio and related environments are installed using the Visual Studio installer. However, multiple dotnet environment variables may appear because a previously installed environment has not been fully uninstalled or for other reasons.

You can fix this issue with the following steps:

1. Open the environment variables of your computer and check whether there are more than two dotnet paths in Path, as follows:

2. At this time, you need to check your real dotnet path, and then delete the redundant ones. This is my correct path

3. Then open CMD again and enter "dotnet --info", then the SDK will display normally

4. Finally, please reopen Visual Studio and you should be able to see your project
