How to fix "error CS0656: Missing compiler required member 'Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo.Create'"
Question
I'd like to use IBM's Watson API SpeechToText on Unity (ver.2018.4.13). First, I'm reading https://github.com/watson-developer-cloud/unity-sdk/blob/master/README.md and tried to install but console said
Assets\\unity-sdk-core-1.2.0\\Utilities\\CredentialUtils.cs(268,70):warning CS0618: 'Credential.ApiKey' is obsolete: 'Authentication using legacy apikey is deprecated. Please authenticate using TokenOptions.'
Assets\\unity-sdk-core-1.2.0\\Connection\\RESTConnector.cs(664,24): error CS0656: Missing compiler required member 'Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo.Create'
and
Assets\\unity-sdk-core-1.2.0\\Authentication\\CloudPakForData\\CloudPakForDataAuthenticator.cs(35,31): warning CS0414: The field 'CloudPakForDataAuthenticator.UrlSuffix' is assigned but its value is never used
How can I solve these error and warnings.
Thank you.

This looks like you are not using the latest Unity SDK or core. Please download the latest from https://github.com/watson-developer-cloud/unity-sdk/releases and https://github.com/IBM/unity-sdk-core/releases
Also please set your API Compatibility Level to .NET 4.x
