Async event handlers #1406

Open MisinformedDNA opened 2 years ago

MisinformedDNA commented 2 years ago

Type of issue

Other (describe below)

Description

There should be documentation about how async event handlers work, best practices and pitfalls.

One issue is this documentation from DevExpress that instructs developers to use .GetAwaiter().GetResult();. This which would likely cause deadlocks, and I wanted to point DevExpress to documentation that shows them why this is bad, but cannot find anything official on why it is bad or what the workarounds may be.

There are countless more SO posts about various async issues when using WinForms.
