Missing Method Exception was Unhandled

[ggstamm]

Hello, I have an issue, when I use this line below:
"HipchatClient client = new HipchatClient();"

This is the exception:
_

An unhandled exception of type 'System.MissingMethodException' occurred in HipchatApiV2.dll

Additional information: Method not found: 'Void ServiceStack.Text.JsConfig1.set_DeSerializeFn(System.Func2<System.String,!0>)'.

_

I'm newbie with C#, and don't know how to make this work.

My imports:
using System;
using System.Runtime.InteropServices;
using HipchatApiV2;
using HipchatApiV2.Requests;
using Xunit;
using ServiceStack.Text;

[ggstamm]

My packages:

<package id="Hipchat-CS" version="0.0.52" targetFramework="net45" />
<package id="ServiceStack.Text" version="4.0.50" targetFramework="net45" />

Install ServiceStack.Text version 4.0.56. That worked for me. Hope this helps! @ggstamm

These errors are normally from dependency version mismatchs. Hipchat CS was built against ServiceStack 4.0.56.

I think I probably need to pin the dependency to a specific version.

Doing what haydenthrashsaid should fix the issue though in the meantime.

Thanks for the reply, but I still have the same error, I'm starting to think that it's something about my Visual Studio :(.

I create a Visual C# -> Console Application.

An unhandled exception of type 'System.MissingMethodException' occurred in HipchatApiV2.dll
Additional information: Method not found: 'Void >ServiceStack.Text.JsConfig1.set_DeSerializeFn(System.Func2<System.String,!0>)'.

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using HipchatApiV2;

namespace Console_HipChat_CS
{
    class Program
    {
        static void Main(string[] args)
        {
            string apikey = My API here;
            var client = new HipchatClient(apikey);
            client.SendNotification("Test", "Testing"); 
        }
    }
}

Sorry for disturbing you.
