I\'m porting my existing class library that targets .NET Framework 4.6.2 to .NET Core 1.1.

Looks like some of the methods that are available in .NET Framework version ar

According to this question: Missing syncronous methods for dotnet core?，NetCore/Netstandard support does not yet include Sync implementation of the APIs.

Since CreateQuery and ExecuteQuery are all Sync method, so we couldn’t use it in .NET Core, you could only use ExecuteQuerySegmentedAsync,TableQuery, Fluent API and handle the continuation token it returns. More details, you could refer to follow codes:

Update:

public static void Main(string[] args)
{
    var result = Get("Aut_Fantasy", "Cert-0000000020", "DifferenetPartitionTest");
    Console.Write(result.PartitionKey);
    Console.Read();
}

public static T Get(string partitionKey, string rowKey, string tableName) where T : ITableEntity, new()
{
    CloudTable table = ConnectToTable(tableName);
    TableQuery employeeQuery = new TableQuery().Where(
        TableQuery.CombineFilters(
            TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, partitionKey),
            TableOperators.And,
            TableQuery.GenerateFilterCondition("RowKey", QueryComparisons.LessThan, rowKey))
        ).Take(1);
    var re = new T();
        TableContinuationToken continuationToken = null;
    do
    {
        Task> employees = table.ExecuteQuerySegmentedAsync(employeeQuery, continuationToken);
        TableQuerySegment employeess = employees.Result;
        re= employeess.FirstOrDefault();
        continuationToken = employeess.ContinuationToken;
    } while (continuationToken != null);
    return re;
}

Hope this could give you some tips.
