Is Blazor supported by IE?

Only server-side Blazor is supported by Microsoft’s Internet Explorer IE 11 when additional polyfills are used. Client-side Blazor is not supported by Internet Explorer due to the incompatibility of WebAssembly. You need to add the following polyfills in the _Host.cshtml page to support Internet Explorer.
