I need to invoke a Blazor Wasm method from my script code, and have been successful in doing that using the code below. This works when the code is in a native JS file, but I get a compiler error (cannot find name 'DotNet') when I try to place it in a TypeScript
file. Is there some way to do this in TS?

Thanks. Steve
DotNet.invokeMethodAsync('ME Web', 'PassBBDetailJsonArray', jsonBBDetailsArray) .then(function (result) { document.getElementById("msgGetBBDetails").innerText = result; }) .catch((event) => { console.error('StaticBlazorMethod error'); });All-Star

Thanks, Bruce. Good to know the situation.
Update: This reply from Bruce to a different question contains the answer: https://forums.asp.net/t/2168544.aspx?How+to+Pass+IndexedDB+Data+to+Blazor+using+TypeScript+During+Initialization.
Include the JSInterop interface definitions in the project as a d.ts file.
