CodePudding user response：

When you publish an app, by default dotnet creates both a platform-dependent executable and a platform-independent dll.

The web1 file is the platform-dependent executable and web1.dll is the platform-independent dll.

You can get publish to not create the platform-dependent executable by adding the following section to your .csproj file

<PropertyGroup>
  <UseAppHost>false</UseAppHost>
</PropertyGroup>
