Hello Chris, Jan,

That is, in the second thread you will re-open all the files you need for the calculation in shared mode + read-only (just for productivity ...

Robert, The Workareas list is linked to the fact that the RuntimeState is allocated per thread. It calls GetInstance() to get the current instance. If we make the state asynclocal then we need some other mechanism to keep track of RDDs per thread. No changes are expected to the Workareas property. I ...

This is fine for classic multi-threaded programming based on Thread classes, but causes problems in the more modern style based on asynchronous tasks (Task class, async, await). The problem is that asynchronous tasks ...

Hallo Jörg, Es wird aber wahrscheinlich nicht mehr praktikabel zu sein, wenn die SQL-Datenbank in der Cloud arbeiten soll?

Die Anwendung kann in zwei Modi arbeiten: ...

Hi Chris,
Many thanks!

Chris,
Thanks!

Here is an example project:
