Develop Reference

Why is visual studio telling me I am running a different version of C# than what I am targeting in a WCF Service Project?

I created a new WCF Service Project targeting framework 4.7.2 in Visual Studio, but when I try to code an interpolated string, i get an error that interpolated strings are not available in C#5, please use version 6 or higher. The only place I see any mention of versioning is in the web.config file, and I confirmed that it indeed is targetting 4.7.2. Does anyone know how to fix this, and why its happening?

C# WCF with IIS AAR cant process metadata

I have a WCF Service hosted in IIS with BasicHttpBinding.
WCF is available through IIS and is routed to an internal HTTP Port with IIS Reverse Proxy (AAR).
When I want to embed the WCF in VisualStudio from my IIS then I can't add the Service Reference and get this error:
The removeserver has returned an error: (415) Cannot process
the message because the content type 'application/soap+xml;
charset=utf-8' was not the expected type 'text/xml;
charset=utf-8'..HTTP GET Error URI:
http://myServer/WebServices/WCF_mywebapi/Service.svc
However if I disable the IIS ARR Reverse proxy (and Host WCF directly on Port 80) then there is no Error.
Is there a problem with ReverseProxy handling my Request?
How can I debug them?
I have some other WebServices on WsHttpBinding and they work well on retriving metadata.
The web.config must be right because I can embed the wervice without active ARR.
I know that there are a few solutions to this error but none of them mention the AAR Module as source.
Can you help me?
Edit: Here whe web.config from WCF:

My Server Config for Proxy:
<rule name="ReverseProxyInboundRule1" enabled="true" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
<action type="Rewrite" url="http://127.0.0.1:1010/{R:1}" />
</rule>
And I disabled svc ISAPI module for IIS Proxy Instance (because the're handled by IIS Instance on other port):
<handlers>
<remove name="svc-ISAPI-4.0_64bit" />
<remove name="svc-ISAPI-4.0_32bit" />
<remove name="svc-Integrated-4.0" />
</handlers>
Thanks :)

There was no endpoint listening at {0} that could accept the message. This is often cause by an incorrect address or SOAP action. (Xamarin Android)

I can normally run the application on the emulator and do some action before, but for some reason this suddenly appeared even though the webservice runs properly on the browser.
I looked for a solution with similar case as this but I can't seem to figure out how to do it because I am using Xamarin which has a different way of adding service reference.
Here are my codes:

Which emulator are you using it might be the problem of your emulator. Use genymotion emulator it is the works smooth without any problems. And a service hosted on localhost can be accessed through a proxy or with the IP.

Already solved by creating a webservice again and now it is working properly.

There was no endpoint listening at https://localhost:44302/Service7.svc that could accept the message

I created a WCF service hosted on IIS and posted with HTTPS. When I launch my client code, I got error:
An unhandled exception of type 'System.ServiceModel.EndpointNotFoundException' occurred in mscorlib.dll
Additional information: There was no endpoint listening at https://localhost:44302/Service7.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
However, when I launch https://localhost:44302/Service7.svc in the browser, I can get "You have created a service." like the picture shown below:
Those two url are exactly the same and I am confused why I am getting this error.
