How can we log both user and bot messages to comos db in microsoft bot framework

I have created a chat bot using microsoft bot framework v4 sdk. I wanted to log bot user and bot messages to cosmos db.
i am able to log only user messages using below blog https://learn.microsoft.com/en-us/azure/bot-service/bot-builder-howto-v4-storage?view=azure-bot-service-4.0&tabs=csharp#using-cosmos-db .
I expect to log both user and bot responses.

Thankfully, this is pretty easy since ItranscriptLogger and TranscriptLoggerMiddleware already exist.
Create your TranscriptStore Class (new Class file)
using Microsoft.Bot.Builder;
using Microsoft.Bot.Builder.Azure;
using Microsoft.Bot.Schema;
using System.Collections.Generic;
using System.Threading;
using System.Threading.Tasks;
namespace QuickTestBot_CSharp
{
public class CosmosTranscriptStore : ITranscriptLogger
{
private CosmosDbStorage _storage;
public CosmosTranscriptStore(CosmosDbStorageOptions config)
{
_storage = new CosmosDbStorage(config);
}
public async Task LogActivityAsync(IActivity activity)
{
// activity only contains Text if this is a message
var isMessage = activity.AsMessageActivity() != null ? true : false;
if (isMessage)
{
// Customize this to save whatever data you want
var data = new
{
From = activity.From,
To = activity.Recipient,
Text = activity.AsMessageActivity().Text,
};
var document = new Dictionary<string, object>();
// activity.Id is being used as the Cosmos Document Id
document.Add(activity.Id, data);
await _storage.WriteAsync(document, new CancellationToken());
}
}
}
}
Create and Add the Middleware (in Startup.cs)
[...]
var config = new CosmosDbStorageOptions
{
AuthKey = "<YourAuthKey>",
CollectionId = "<whateverYouWant>",
CosmosDBEndpoint = new Uri("https://<YourEndpoint>.documents.azure.com:443"),
DatabaseId = "<whateverYouWant>",
};
var transcriptMiddleware = new TranscriptLoggerMiddleware(new CosmosTranscriptStore(config));
var middleware = options.Middleware;
middleware.Add(transcriptMiddleware);
[...]
Result:
Note:
This is probably the easiest/best way to do it. However, you can also capture outgoing activities under OnTurnAsync() using turnContext.OnSendActivities() and then write the outgoing activity to storage, as well.

Retrieve TFS Test Steps always returns count of 0

I am trying to retrieve test steps (aka "actions") that have been added to a test case in TFS (2017.2) using the API (Microsoft.TeamFoundationServer.ExtendedClient v15.112.1). My current implementation always returns 0 test steps, although the actual test case has steps. I tried this as well in a clean new Team Project without any Work Item customization and even there it returns 0 steps. My implementation uses the older API (based on SOAP webservices), because it seems the newer http based API does not yet implement test steps. This is the code I have used:
private void GetTestStepsForTestCase(int testCaseId, int testSuiteId,
string teamProjectName, Uri tfsUrl)
{
TfsTeamProjectCollection tpc = new TfsTeamProjectCollection(tfsUrl);
ITestManagementService itms = tpc.GetService<ITestManagementService>();
ITestManagementTeamProject ittp = itms.GetTeamProject(teamProjectName);
ITestSuiteBase suite = ittp.TestSuites.Find(testSuiteId);
ITestCaseCollection testCaseCollection = suite.AllTestCases;
ITestCase itestCase = testCaseCollection.FirstOrDefault(t => t.Id == testCaseId);
foreach (Microsoft.TeamFoundation.TestManagement.Client.ITestAction itestAction in itestCase.Actions)
{
// Do something
}
}
Anyone?

You can use below sample to retrieve the test case steps from a specific test suite, it works on my side:
Install the nuget package : Microsoft.TeamFoundationServer.ExtendedClient - 15.112.1
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.TestManagement.Client;
using Microsoft.VisualStudio.Services.Client;
using System;
namespace RetrieveTestSteps
{
class Program
{
static void Main(string[] args)
{
var u = new Uri("http://server:8080/tfs/DefaultCollection");
var c = new VssClientCredentials();
TfsTeamProjectCollection tpc = new TfsTeamProjectCollection(u, c);
tpc.EnsureAuthenticated();
ITestManagementService itms = tpc.GetService<ITestManagementService>();
ITestManagementTeamProject ittp = itms.GetTeamProject("LCScrum");
ITestSuiteBase suite = ittp.TestSuites.Find(352);
ITestCaseCollection testCaseCollection = suite.AllTestCases;
foreach (var tc in testCaseCollection)
{
ITestCase testcase = ittp.TestCases.Find(tc.Id);
foreach (ITestAction action in testcase.Actions)
{
Console.WriteLine(String.Format("{0} - {1}", testcase.Id, action));
}
}
Console.Read();
}
}
}

OK, I finally figured out this one myself. The answer and comments of Andy helped me validate that my code is correct. I just discovered that my code worked fine when NOT debugging! When debugging, at some point I noticed this:
So probably because of lazy loading somewhere, it is not possible to verify the count of the attachments debug-time (see post here: Lazy<T>: "The function evaluation requires all threads to run").

c# Cannot create InlineKeyboardButton

I am creating a telegram bot, but I am unable to create any InlineKeyboardButton objects.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Telegram.Bot.Types.InlineKeyboardButtons;
namespace BuildAutomation.Controllers
{
public class Test
{
public TestMethod()
{
var none = new InlineKeyboardButton("No", "build|no");
var yes = "Yes";
var betaControl = new InlineKeyboardButton(yes, "build|betacontrol");
var betaNode = new InlineKeyboardButton(yes, "build|betanode");
var betaBoth = new InlineKeyboardButton(yes, "build|betaboth");
InlineKeyboardMarkup menu;
menu = new InlineKeyboardMarkup(new[] { betaBoth, none });
}
}
}
I keep getting the error 'Cannot create an instance of the abstract class or interface 'InlineKeyboardButton'. I realize that InlineKeyboardButton is an abstract class, but i see many examples creating an object of InlineKeyboardButton.
Did I miss something?
example 1
example 2
example 3

Instantiation of InlineKeyboardButton directly was correct in previous versions.
There is a new commit for about one month ago which indicates that InlineKeyboardButton is made abstract from then on. You must use derived classes instead. InlineKeyboardUrlButton, InlineKeyboardPayButton and etc. are all derived from InlineKeyboardButton.
It seems that the examples' repository is not updated yet.
Check this link for more details about the mentioned commit:
https://github.com/TelegramBots/telegram.bot/commit/ddaa8b74e3ab5eab632dbe2e8916c2fe87b114a3

Use InlineKeyboardCallbackButton Example, InlineKeyboardCallbackButton("Yes", "CallBackData") instead of InlineKeyboardButton("Yes", "CallbackData")

You couldn't create a new instance of abstraction class. So use sample bellow
var KeyboardButons = new InlineKeyboardButton[][]
{
new InlineKeyboardButton[]
{
InlineKeyboardButton.WithCallbackData("سفارش", callbackQueryData) ,
InlineKeyboardButton.WithCallbackData("بازگشت", "return")
}
};
var replyMarkup = new InlineKeyboardMarkup()
{
InlineKeyboard = KeyboardButons
};

C# Windows Service - this keyword error

I have the following code which works fine when I use it within a Windows Forms application, however the application I'm writing needs to run as a Windows service, and when I moved my code into the Windows Service template in Visual Studio 2015 Community Edition, I get the following error.
Cannot implicitly convert type "MyWindowsService.Main" to "System.ComponentModel.ISynchronizeVoke". An explicit conversion exists (are you missing a cast?)
Could anyone shed some light on why I am getting this error, and what I need to do to resolve it?
The code which throws the error is the line below, and it is located within the OnStart method of my main class (named Main.cs). The code is used to create an instance of the DataSubscriber class (AdvancedHMI library).
dataSubscribers[dataSubscriberIndex].SynchronizingObject = this;
It has to have something to do with the fact that the code is in a Windows service template, because using this works perfectly in my forms application running the same code.
UPDATE
Correction, I've attempted to cast this to the required type, and now get the following error on run.
Additional information: Unable to cast object of type 'MyWindowsService.Main' to type 'System.ComponentModel.ISynchronizeInvoke'.
Code:
dataSubscribers[dataSubscriberIndex].SynchronizingObject = (System.ComponentModel.ISynchronizeInvoke)this;
UPDATE
I've included the entire contents of the Main.cs file from my Windows Service application.

dataSubscriberIndex++;
}
}
}
}
private void subscribeCallback(object sender, MfgControl.AdvancedHMI.Drivers.Common.PlcComEventArgs e) {
// code removed as it is irrelevant
}
}
}

The error message says this:
An explicit conversion exists (are you missing a cast?)
So add a cast like this:
dataSubscribers[dataSubscriberIndex].SynchronizingObject = (ISynchronizeInvoke)this;
^^^^^^^^^^^^^^^^^^^^
//Add this

If you've got a console app, the easiest way to convert it to a windows service is by using Topshelf, a nuget package which lets you run in either console mode or nt service mode.
Here's the quickstart guide.
We use it to write services all the time and it helps you avoid this kind of fragile shenanigans.

How can I roll back changes with Entity Framework 5 within a Unit Test project

I'm playing with Entity Framework, and I have a Unit Test project that I want to exercise what I've done so far. I'd like to have it not actually update my test database when it's done. If I was working in SQL I would create a transaction and then roll it back at the end.
How can I do the same thing here?
As I understand it, context.SaveChanges(); is effectively doing the write to the database. And if I don't have that, then allCartTypes is empty after I assign it context.CarTypes.ToList()
Here's an example of one of my Test classes.
using System;
using System.Diagnostics;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Trains;
using System.Linq;
namespace TrainsTest
{
[TestClass]
public class TestCarType : TestBase
{
[TestMethod]
public void TestCarTypeCreate_Success()
{
var tankerCarType = new CarType {Name = "Tanker"};
var boxCarType = new CarType { Name = "Box" };
using (var context = new TrainEntities())
{
context.CarTypes.Add(tankerCarType);
context.CarTypes.Add(boxCarType);
context.SaveChanges();
var allCartTypes = context.CarTypes.ToList();
foreach (var cartType in allCartTypes)
{
Debug.WriteLine(cartType.CarTypeId + " - " + cartType.Name);
}
}
}
}
}
I know I'm missing something fundamental, but I don't know what it is. and my googling has been fruitless.

There's a MSDN article about ef transactions.
