Configure Nuget Package Source using Visual Studio Code to add packages from my local Folder

Question

Configure Nuget Package Source using Visual Studio Code to add packages from my local Folder.

1. First I added an extension for Nuget Package Manager GUI
2. In settings below is what I added.

{
    "terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe",
    "git.terminalAuthentication": false,
    "terminal.integrated.rendererType": "canvas",
    "workbench.editorAssociations": {
        "*.ipynb": "jupyter.notebook.ipynb"
    },
,
    "workbench.colorTheme": "Visual Studio Light",
    "explorer.confirmDragAndDrop": false,
    "nugetpackagemanagergui.nuget.searchPackage.urls": [
       "C:\\packages"
    ],
    "nuget"
}

3. I also included a nuget.config file in my project root folder. "C:\packages"
4. Now how do I add my custom created nuget package to my project.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="MyLocalNuget" value="C:\packages" />
  </packageSources>
</configuration>

5. Below command fails to execute, I get this message "There are no versions available for the package 'Framework.Blazor.1.0.0'."

    dotnet add package Framework.Blazor.1.0.0 

References are not added to my Project File

<Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="6.0.2" />
    <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.DevServer" Version="6.0.2" PrivateAssets="all" />
  </ItemGroup>

</Project>

Please suggest what I missed. Thank you
