Hi @stone89son,

As you mentioned, there are several ways for script code to be operating asynchronously, including via direct invocation of managed async methods, blocking calls, etc. – and any number of such operations can be in flight simultaneously.

Therefore, generally speaking, there are no shortcuts. The host and script engine must work together if synchronization is required. For example, the host can hand the script code an event to set when it's done. Alternatively, the script code can give the host a promise or task that tracks the progress of the operation in question.

Good luck!
