PS C:\Users\Anjali kumari> dotnet-ef
A fatal error occurred. The required library hostfxr.dll could not be found.
If this is a self-contained application, that library should exist in [C:\Users\Anjali kumari.dotnet\tools.store\dotnet-ef\6.0.1\dotnet-ef\6.0.1\tools\netcoreapp3.1\any].
If this is a framework-dependent application, install the runtime in the global location [C:\Program Files\dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [HKLM\SOFTWARE\dotnet\Setup\InstalledVersions\x64\InstallLocation].
