The polyfill js is now distributed via a nuget package and is referenced by 

<script src="_framework/blazor.polyfill.min.js"></script>

I've updated your sample and now gives it gives a js error.

I've attached the updated sample.

Could you try a couple of things?

1) Does any of the grid/tree functionality work for you once the page has loaded e.g. tree collapse/expand, grid columns sort or page. Doesn't for me.
2) Go to the Console tab in dev tools and then refresh the page. Make sure its a refresh else the dev tools will close and you'll miss the error. 

I think you may be missing the error on page load as IE will not log the error to the console unless the dev tools are open at the time.

Hi Michael,   
  
Thanks for the update.  
  
We have validated the reported issue and we would let you know that in .NET 5.0, the Microsoft Blazor Server & Web Assembly are not supported with the IE11 browser. Please refer to the below documentation links for more details.  
  
  
However, we have checked further with Blazor.Polyfill and the cause of the issue is due to the JS isolation is not working in IE11 with .NET 5.0. Please refer to the below GitHub issue thread.  
  
kindly get back to us further assistance. 
  
Regards, 
Pon selva

Thanks for the update on IE11 status and Blazor.polyfill.

What will Syncfusions approach to IE11 be now? Will you still test against it? 

PS Pon Selva Jeganathan Syncfusion Team January 22, 2021 10:18 AM UTC

Hi Michael,   
 
Thanks for the update.  
 
As per official updates from Microsoft, we won't recommend the IE11 for Blazor application with .NET 5.0 target since it's not supported.  
 
 
However, we still support and doing testing against our components with .NET Core 3.1 targeted application. 
 
 
Please let us know if you have any concerns. 
 
Regards, 
Pon selva
