Chat on Gitter NuGet Status

Configure async code's ConfigureAwait at a global level.

See Milestones for release notes.

This is an add-in for Fody

It is expected that all developers using Fody become a Patron on OpenCollective. See Licensing/Patron FAQ for more information.

Usage

See also Fody usage.

NuGet package

Install the ConfigureAwait.Fody NuGet package and update the Fody NuGet package:

PM> Install-Package Fody
PM> Install-Package ConfigureAwait.Fody

The Install-Package Fody is required since NuGet always defaults to the oldest, and most buggy, version of any dependency.

How to use it

By default, ConfigureAwait.Fody doesn't change any code. Set a configure await value at the assembly, class, or method level.

  • [assembly: Fody.ConfigureAwait(false)] - Assembly level
  • [Fody.ConfigureAwait(false)] - Class or method level

Explicitly configured awaiters will not be overwritten by the weaver, allowing exceptions to the Assembly / Class / Method level setting.

Add to FodyWeavers.xml

Add <ConfigureAwait/> to FodyWeavers.xml

<Weavers>
  <ConfigureAwait/>
</Weavers>

It is also possible set the default ContinueOnCapturedContext in the xml config:

<Weavers>
  <ConfigureAwait ContinueOnCapturedContext="false" />
</Weavers>

Example

Before code

using Fody;

[ConfigureAwait(false)]
public class MyAsyncLibrary
{
    public async Task MyMethodAsync()
    {
        await Task.Delay(10);
        await Task.Delay(20).ConfigureAwait(true);
    }

    public async Task AnotherMethodAsync()
    {
        await Task.Delay(30);
    }
}

What gets compiled

public class MyAsyncLibrary
{
    public async Task MyMethodAsync()
    {
        await Task.Delay(10).ConfigureAwait(false);
        await Task.Delay(20).ConfigureAwait(true);
    }

    public async Task AnotherMethodAsync()
    {
        await Task.Delay(30).ConfigureAwait(false);
    }
}
