UseSpaStaticFiles() not found after migrating to dotnet Core 3.1

After upgrading my .NetCore 2.2 application to Net Core 3.1. I am now facing issue in the startup.cs file related to a UseSpaStaticFiles() method.

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        app
            .UseCors("default")
            .UseStaticFiles()
            .UseSpaStaticFiles(); // this line is giving me error.
       .....
    }

The error says :

Error CS1061 'IApplicationBuilder' does not contain a definition for 'UseSpaStaticFiles' and no accessible extension method 'UseSpaStaticFiles' accepting a first argument of type 'IApplicationBuilder' could be found (are you missing a using directive or an assembly reference?)

To resolve the issue I have tried installing Microsoft.AspNetCore.SpaServices package from Nuget and that also didn't help.

The ASP.NET Core 2.2 to 3.0 migration guide explains that some assemblies were removed from the main ASP.NET Core package to reduce the deployment size and allow people to only include what they really need.

The section Add package references for removed assemblies. That section includes a list of the removed assemblies and the packages that need to be added back.

For SPA Services, the packages are Microsoft.AspNetCore.SpaServices and Microsoft.AspNetCore.SpaServices.Extensions

3.0 is a major version so breaking changes are expected. The Breaking Changes links to list of breaking changes by category and the detailed Github work issues

This method is contained in the 

Microsoft.AspNetCore.SpaServices.Extensions

NuGet package.
