Issue Description

I have a setup in our tests where we have a service provider which generates services, and each of our tests is arranged as a separate request (scope). We also have some default value prefilling on before scenario (actual logic is more complex, but for sake of example it can be simplified).

The issue here is when we use IHttpContextAccessor, a singleton service, it internally uses AsyncLocal to keep track of the HTTP context. On Specflow, the assigned context in BeforeScenario, can be seen later in the service, however when using reqnroll, it cannot.

Steps to Reproduce

Successful commit (specflow): GedasFX/AsyncLocal_ReqNRoll@99c0c50
Failing commit (reqnroll): GedasFX/AsyncLocal_ReqNRoll@d444e22

Checkout the commits. There is a single test in the test suite.

@GedasFX Could you please also make a commit where you use the latest beta of SpecFlow (4.0.31-beta) to see how the behavior was there?

@gasparnagy GedasFX/AsyncLocal_ReqNRoll@9feaa24 it's Its failing on 4.0.31-beta...

@GedasFX Thx. So this is a side effect of switching the testing to full async in SpecFlow v4. I remember that is was pretty tricky with the AsyncLocal and the execution context, but I don't remember all the details now. Fortunately there is a bunch of tests on the current behavior (https://github.com/reqnroll/Reqnroll/blob/main/Tests/Reqnroll.RuntimeTests/Bindings/BindingInvokerTests.cs#L268).

If you have a bit of time, you can review those tests, maybe it helps understanding the problem, but I can also look at that next week.

Oh I guess you guys sort of figured it out :D planned to check today ^^
