I’m getting this error:
Additional information: Could not load file or assembly ‘System.Collections.Immutable, Version=1.2.3.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
when I’m trying to run this code in C#
IEventHandler userEventhandler = Backendless.Data.Of().RT();
** userEventhandler.AddUpdateListener(“filename != ‘’”, updatedUser =>**
** {**
** MessageBox.Show(“something happend”);**
** });**
