View POST request body in Application Insights

Question

Is it possible to view POST request body in Application Insights?

I can see request details, but not the payload being posted in application insights. Do I have to t

In Asp.Net core it looks like we dont have to use ITelemetryInitializer. We can use the middleware to log the requests to application insights. Thanks to @IanKemp https://github.com/microsoft/ApplicationInsights-aspnetcore/issues/686

 public async Task Invoke(HttpContext httpContext)
    {
        var requestTelemetry = httpContext.Features.Get();

        //Handle Request 
        var request = httpContext.Request;
        if (request?.Body?.CanRead == true)
        {
            request.EnableBuffering();

            var bodySize = (int)(request.ContentLength ?? request.Body.Length);
            if (bodySize > 0)
            {
                request.Body.Position = 0;

                byte[] body;

                using (var ms = new MemoryStream(bodySize))
                {
                    await request.Body.CopyToAsync(ms);

                    body = ms.ToArray();
                }

                request.Body.Position = 0;

                if (requestTelemetry != null)
                {
                    var requestBodyString = Encoding.UTF8.GetString(body);

                    requestTelemetry.Properties.Add("RequestBody", requestBodyString);
                }
            }
        }

        await _next(httpContext); // calling next middleware
    }
