where we have migrated from Xamarin Forms app to MAUI app.

Steps to Reproduce
This is the code we are using to Post to API
protected async Task<TResp> PostFunc<TArgs, TResp>(string uriString, TArgs args)
{
var uri = new Uri(_baseAddress + uriString);
var jsonreq = JsonConvert.SerializeObject(args);
var reqContent = new StringContent(jsonreq, Encoding.UTF8, "application/json");
try
{
var response = await _client.PostAsync(uri, reqContent);
if (response.IsSuccessStatusCode)
{
var respContent = await response.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<TResp>(respContent);
}
else
throw ExceptionFromErrorResponse(response);
}
catch (Exception ex)
{
throw ex;
}
