gamelift client NetworkReachability cunstructor missing in Unity build

Question

I get the following exception during **runtime** on android:

`MissingMethodException: Default constructor not found for type Amazon.Util.Internal.PlatformServices.NetworkReachability`

The code below is executed:

```
var client = new AmazonGameLiftClient(
				"",
				"",
				new AmazonGameLiftConfig { UseAlternateUserAgentHeader = false, RegionEndpoint = RegionEndpoint.USEast1 }
				);
```
I didn't have any issues running the game client on windows and the server running on linux.

Hi @gabetoth, Have you taken a look at this guide which lists out special considerations for Unity support, when using the AWS SDK? https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/unity-special.html

[Commonly](https://github.com/aws/aws-sdk-net/issues/1627), this seems to be an issue with not adding a link.xml file to the Assets folder, that lists all AWSSDK assemblies being used. Could you try this to see if it solves your problem?
