Answer / ravish sharma
We can't say that any framework is thread safe or not?.
Because thread safty is depends on how many threads are accessing a single object. On this basis we can say that thread safe or not....So We cant say that any framework is thread safe or not? so its depend upto you how you are implimenting in your project.
