Is it possible to generate C# classes from a JSON schema using Liquid Studio?

I had added the lines below to my .csproj file, but in the generated class, I get this error message : Error Error Generating Liquid XML Objects Code. Error No schema files provides.

<ItemGroup>
  <None Update="file.json">
    <Generator>LxCodeGenerator</Generator>
    <LastGenOutput>MyClasses.cs</LastGenOutput>
    <CustomToolNamespace>My.Namespaces</CustomToolNamespace>
    <CopyToOutputDirectory>Never</CopyToOutputDirectory>
  </None>
</ItemGroup>

Thanks for your help.
