Issue Description

I took .Net 6 ASP NET Core API example (https://github.com/SpecFlowOSS/SpecFlow-Examples/tree/master/.NET%206/ASP.NET%20Core%20API) and converted it to .Net Core 3.1.

Problem occurs in .Net core 3.1, but works in .Net 6 example

Steps to Reproduce

• set breakpoint on line 23 of CalculatorController
• Debug 'add two numbers...' test

Once stopped on the breakpoint, you can see that releaseLabel variable is null, while it should have value
