Exception when referencing SSAS Tabular model in C#

I am attempting to automate partition refreshes in Azure Analysis Services via C#. I have installed and referenced the latest 'Microsoft.AnalysisServices. ..' assemblies found here:

https://docs.microsoft.com/en-us/azure/analysis-services/analysis-services-data-providers.

I then have the following code:

using System; using Microsoft.AnalysisServices.Tabular;

    public void Run()
    {
        Server asSrv = new Server();

        try
        {

            asSrv.Connect(ASConnectionString);
            Database db = asSrv.Databases.FindByName("HospoIQTabular");
            Model m = db.Model;

            // only refresh 2017 partitions

            m.Tables["Sales"].Partitions["Sales - Post 2017"].RequestRefresh(RefreshType.Full);
            m.Tables["Payments"].Partitions["Payments - Post 2017"].RequestRefresh(RefreshType.Full);

            db.Model.SaveChanges();     // commit which will execute the refresh

        }
        catch (Exception e)
        {
            OnEventLog(e.Message);
        }
        finally
        {
            asSrv.Disconnect();
            asSrv = null;
        }

    }

Connect to the server and database itself works fine. However, attempting to reference 'db.Model' throws the following exception:

The value '2' is unexpected for type 'DataSourceType'.

I've looked but can't find any help anywhere on this. Any thoughts??

For me, the path that worked was C:\Program Files (x86)\Microsoft SQL Server\140\SDK\Assemblies but only after reading Andrae comment which sent me on the right direction

The problem is similar with the NuGet package Microsoft.AnalysisServices.Tabular (v13)

Fortunately you can use the NuGet packages listed here: https://docs.microsoft.com/en-us/azure/analysis-services/analysis-services-data-providers.

In Visual Studio NuGet lists this package as Microsoft.AnalysisServices.retail.amd64
