Originally created by @PrzemekScott on GitHub (Mar 9, 2022).

I've experimented with WM stand alone version locally, with such settings:

Now wanted to experiment with WM as web app and then set it on Azure, but not sure how to implement 'ProxyAndRecordSetting' in appsettings file. When I have it like below:

I'm getting such error:

System.InvalidOperationException: Cannot create instance of type 'WireMock.Settings.IProxyAndRecordSettings' because it is either abstract or an interface.

The way I run WM with configuration is from one of 'examples projects' :

thx

@PrzemekScott
I don't think this is possible.

• https://stackoverflow.com/questions/59124184/options-pattern-interface-abstract-property

I'll investigate why I decided to use an interface instead of a class, and see if I can remove the interface.

I see.
Is then any other way to run WM on Azure in "proxying mode" (when needed - less often) and in "matching mode" (when needed - most of the time) ?

Only workaround for now is to split the settings in two sections:

"WireMockServerSettings": {
},
"ProxyAndRecordSettings": {
}

And then do two calls:

1. GetSection as you have now on WireMockServerSettings
2. GetSection on ProxyAndRecordSettings
3. Combine the outcome from step 2 in the resolved object from step 1

I've created a preview version which only has classes for settings; no interfaces anymore.

Preview version = 1.4.37-ci-15956.

@StefH ,
Thanks for that change. It works well, starting server with all settings from the appsettings.json file"

Yet, there is one thing which I do not understand.
When I Run the App - I'm using JB Rider as my IDE - in next several seconds the browser is opened with this url as below:

Unfortunately @StefH, I've started WM project as a POC under one of test automation projects in my organisation and all of such projects are set as 'Internal', it is also bonded with our internal tools, accesses, so, unfortunately I can't share it.

What we’ve checked is that colleagues working with Visual Studio IDE are not facing this “action” of opening browser when ‘Program’ is run - it's only happening when "Program" is run in my JB Rider (on macOS).

Can you share your appsettings.json and the startup code?

From that I can try to reproduce it

So as it also did for my colleagues using Visual Studio. I will try to contact Jet Brain and as for some support. Maybe, just an assumption, that when JB Rider is Run(ning) web app type App, it opens it on some predefined port. But I couldn't find it in settings.

Anyway, thank you StefH for help and changing interface to class in appsettings. I think we can consider this Question as closed.
