Can You Use Async Methods in C# Constructors?

Can a C# constructor call an asynchronous method?

Constructors in C# are typically used to initialize instance fields or set up infrastructure. However, developers may encounter situations where they need to perform asynchronous operations in the constructor.

Detailed explanation of the problem

The problem occurs when calling asynchronous methods from the constructor, which returns control to the caller after starting the task. Because constructors execute in a synchronized context, using await or Task.Result may block the UI thread, causing the application to potentially become unresponsive.

Recommended solutions

To avoid blocking the UI thread and ensure correct asynchronous processing, it is recommended to consider the asynchronous nature of the download process when designing your application. The page constructor should set up a view indicating that the data is being retrieved and initiate the download operation. Once the download is complete, the page should be updated to display the retrieved data.
