Hello. I am very new at Visual Studio for Mac and I have a simple Xamarin project. I would like consume the web service at I add a web service reference. I think I need to add a reference to System.ServiceModel, but I am not sure how do that. I have search for a dll on my system, but it does not seem to be there. I have searched Nuget, but I a not sure what package I really need. I have attempted to add System.ServiceModel.Primatives and System.ServiceModel.Http through Nuget, but I always get the error:

Attempting to resolve dependencies for package 'System.ServiceModel.Web.1.0.0' with DependencyBehavior 'Lowest'
Resolving dependency information took 0 ms

You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile111', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

and similar Profile111 errors.

I have updated my OS and Visual Studio for Mac to the latest. I am really not sure what this error means or if I am pulling the correct NuGet packages. What am I doing wrong? Any help or suggestions would be truly appreciated.

    What kind of web service?

  • So, I believe when I added the web reference I used the default of WCF for the web service.

    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "")]
    [System.Runtime.Serialization.DataContractAttribute(Name="LetterSolutions", Namespace="")]
    public partial class LetterSolutions : object, System.Runtime.Serialization.IExtensibleDataObject {
        private System.Runtime.Serialization.ExtensionDataObject extensionDataField;
        private string anagramField;
        public System.Runtime.Serialization.ExtensionDataObject ExtensionData {
            get {
                return this.extensionDataField;
            set {
                this.extensionDataField = value;

    However, I get errors like "The type or name 'IExstensibleDataObject' does not exist in the namespace 'System.Runtime.Serialization' (Are you missing an assembly reference?) I guess I am not sure what I need to add a reference to or how to add it. Any ideas anyone?
