Interop with synchronous code

When working with existing projects and introducing async code to the system, there will be points where synchronous and asynchronous code intersect. We have already seen some examples of how to handle this interop in this chapter. In this section, we will focus on that interop in both directions: sync calling async and async calling sync.

We will create a sample project with classes containing synchronous methods representing legacy code and another set of classes with modern async methods.

Let’s start by discussing how to consume async methods in your legacy synchronous code.

Executing async from synchronous methods

In this example, we will be working with a .NET console application that gets a patient and their list of medications. The application will call a synchronous GetPatientAndMedications method that in turn calls an async GetPatientInfoAsync method:

  1. Start by creating a new .NET console application
  2. Add Patient...
