Looks good, I just have a few comments.

Could you please add "Fixes #219" To the PR description to link it to the issue

[Daniel-Svensson]

it would be nice (but not mandatory) if you could update the changelog.md with some detail as well

[Daniel-Svensson]

The changes looks good, now you only need to make the build pass and have a look if the sonarcloud check reports any relevant issues to fix (visible a short while after build is successfull)

[Daniel-Svensson]

@papaneko I had a look at the build and it seems you get compile error because UnwrapTaskResult is private.

I suggest changing it to private protected instead to fix the build

[Daniel-Svensson]

It seems one test is failing, I am running a new build against master and waiting to see if the same test fails there https://dev.azure.com/OpenRiaServices/OpenRiaServices/_build/results?buildId=513&view=results

[Daniel-Svensson]

it seems like the failing tests succeeds in master but not for this PR.

It needs a bit further investigation, i've retriggered the build for the PR and it still failed.
It is hard to say at the moment if it might be a timing related issue or something else.

It does look like there is something in this PR which triggers the test failure
