AddHttpMessageHandler throwing an exception about specflow.dependencyinjection

[MGrgov90]

I'm using the latest prerelease package. https://github.com/solidtoken/SpecFlow.DependencyInjection/releases/tag/v4.0.0-preview.1

Hey @MGrgov90, thanks for raising this issue.

I think this should work if both AuthenticationHandler and TokenProviderFactory were added as regular dependencies. I'm not sure how the plugin would know that AddHttpMessageHandler uses a different service provider.

Two questions:

1. can you post the actual exception message?
2. can you try this with plugin v3.9.2 (it has a different bind mapping implementation)

[MGrgov90]

The exception says that the key is not found, and basically the problem is trying to get value from the BindMappings dictionary. Yes, in v.3.9.2 everything works. Still, the reason I tried to upgrade is a need for MemoryCache which I'm unable to use in this version since registering Singleton instances is basically not working.

P.S. The registration is done correctly:

services.AddScoped<TokenProviderFactory>();
services.AddScoped<AuthenticationHandler>();

services.AddHttpClient("clientName", client =>
{
    client.BaseAddress = new Uri("base address");
}).AddHttpMessageHandler<AuthenticationHandler>();

Hi @mbhoek any progress or recommendation about the described problem? Do you need any additional information, so that you can more easily check the described problem?

Thank you for your contribution. Unfortunately I have postponed working on this plugin until I get a better understanding of the future of the SpecFlow project. If they continue, all my focus will be on supporting SpecFlow v4.
