No chart rendered on server-hosted project

Alas, not having any luck with a brand-new server-hosted Blazor project. I have added the nuget package to both client and server projects and followed the instructions in GitHub and on the wiki to add the example PieChart.

A couple of observations which might provide clues…

• env.WebRootPath is actually null when I run my server project. I’ve tried using this code…

 if (string.IsNullOrWhiteSpace(env.WebRootPath))
            {
                env.WebRootPath = System.IO.Path.Combine(Directory.GetCurrentDirectory(), "wwwroot");
            }
            ChartJsBlazor.AddStaticResourcesToWebRootPath(env.WebRootPath);

but the chart is still not displayed.

• I can’t find any way to get PieChartAnimation so have just commented out the “Animation=” assignment in the example code.

I’ve also tried the linker.xml fix suggested in #20 but this makes no difference.

I notice that the startup code in program.cs is quite different between the sample code in GitHub (which does work!) and my actual server project. Mine looks like…

 public class Program
    {
        public static void Main(string[] args)
        {
            BuildWebHost(args).Run();
        }

        public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseConfiguration(new ConfigurationBuilder()
                    .AddCommandLine(args)
                    .Build())
                .UseStartup<Startup>()
                .Build();
    }

Maybe this is a framework version problem?

I created sample pie project for blazorserverside dotnet 3.0.100-preview5-011568 https://github.com/oleksiizapara/ChartJsBlazorSample

Yes, the server-side samples work equally well to the client-side samples. I’m closing the issue.

As always don’t hesitate to reopen it if you encounter problems.
