When hosted under subfolder (both under IIS and Kestrel), stuck at homepage spinner

[martinussuherman]

Steps to reproduce:

1. Clone this repo
2. Add these lines on Startup.cs

            // Add these 2 lines
            string basePath = Configuration.GetValue<string>("BasePath");
            app.UsePathBase(basePath);

            app.UseHttpsRedirection();
            app.UseStaticFiles();

3. Add this line on appsettings.json

"BasePath": "/BlazorSamples"

4. Run the solution (dotnet run)
5. Open browser, go to: http://localhost:5000/BlazorSamples

Expected result:
Samples homepage loaded succesfully.

Result:
Samples homepage stuck (only display loading spinner)

Is there anything missing that I need to add/configure to enable this scenario? Thank you in advance.

Update:
Found this error on the dotnet run console:

Hi @martinussuherman

Thanks for your interest in Syncfusion.

We have checked with your reported issue in Sub folder hosting navigation. We suspect that you missed to add the '/' in end of the URL in your browser. So, could you please add '/' in you browser URl like 'http://localhost:5000/BlazorSamples/' and ensure it again?

Please let us know if you have any concerns.

Regards,

Hi @kmuthukumar23, I've tried your suggestion, and it does works when using Kestrel, but unfortunately when hosted under IIS your workaround didn't work.
