I am attempting to get SciChart working in a Blazor Server app.

I have followed the examples here:

I have the following line in my “_Layout.cshtml” file in the head section:

<script src="" crossorigin="anonymous"></script>

In my scichart js I have:

export async function initSciChart() {

However when I call this over JSInterop i get the following error:

Error: Microsoft.JSInterop.JSException: SciChart.SciChartSurface.useWasmFromCDN is not a function
TypeError: SciChart.SciChartSurface.useWasmFromCDN is not a function

How do we set this up properly to access the scichart modules in a blazor server application?

Thank you,

I’ve been trying to implement the scichart js blazor wrapper in a serverside application. The chart starts to load, but gives the following error:
Failed to load resource: the server responded with a status of 404 () :5001/

it looks like is in the wrong place, but as far as I can tell it’s where it should be (in wwwroot).

is there something special I need to do in sever side? I can get it working fine in webAssembly Blazor
