In the .NET Framework and in the .NET Core Framework there’s a proliferation of async methods. In the C# language ad hoc keywords also make it trivially easy to implement async calls. The question is only one: when is async necessary? During the session we’ll start from a few ASP.NET (Core) examples to illustrate the possible benefits of async but also scenarios when async has more of some much ado for nothing. Fire-and-forget calls and true business parallelism will be analyzed as long as the use of async methods for data access through Entity Framework (Core).
