Actualy this library target netstandard1.0(net45) for Common and netstandard1.3(net46)
(Acording to this: -> https://docs.microsoft.com/dotnet/standard/net-standard#net-implementation-support)

Solutions:

• Solution 1: you upgrade your source code to atleast net46
• Solution 2: we do the required things in order to target netstandard1.1 or net45

For now, we add a #if !NETSTANDARD1_1 in the extensions file.
So, any netstandard1.1 will not be able to use the extensions related to the Class File

GraphQL.Client.1.0.0.zip

@joemcbride I'm not happy using Precompilation dependencies.
The other way is delete the GetFromFile and PostFromFile methods of src/GraphQL.Client/GraphQLClientExtensions.cs

It's a little breaking change, but i dont think that its a problem at this point. What do you think?
