Seems to be a similiar problem field as writing blocking functions that call async functions in C# and co-existence of synchronous and asynchronous code. There are numerous recommendations such as https://learn.microsoft.com/en-us/archive/msdn-magazine/2015/july/async-programming-brownfield-async-development#the-blocking-hack https://learn.microsoft.com/en-us/archive/msdn-magazine/2015...
