asp.net mvc - Entity framework exception while fetching entities -
i using entityframework , mvc web api project, below code entity. issue when calling 1 method throws error
a second operation started on context before previous asynchronous operation completed. use 'await' ensure asynchronous operations have completed before calling method on context. instance members not guaranteed thread safe
i want mention few things, using singleton object context using autofac , owin, api hosted on azure , method calling method can async or not.
public iqueryable<entity> all() { return this.context.entities; } public entity one(expression<func<entity, bool>> predicate) { return this.all().firstordefault(predicate); }
thank you.
