Use cases ?

[ignatandrei]

Could you please describe use cases?

[fredericDelaporte]

See NHibernate for an example use case. Almost all of its async API is generated by this generator. Its async tests are generated by it too.

This generator can be useful when building a library that needs to expose both sync and async apis. By using it, you can implement only sync apis (e.g. ReadFile) and leave the async apis e.g. ReadFileAsync) to be generated by the generator.

In addition to NHibernate you can also check the following projects that are also using it (the configuration is inside AsyncGenerator.yml):
NHibernate-Caches
StackExchange.Redis.Resilience
Breeze.NHibernate
