The type or namespace name 'Dialogs' does not exist in the namespace 'Microsoft.Bot.Builder'

Question

I'm building a chat bot with Microsoft Azure on .NET Framework C#, installed all the references, but after update to Microsoft.Bot.Builder 4.0.7 this reference is unable to find it and showing this type of error:

Error CS0234 The type or namespace name 'Dialogs' does not exist in the namespace 'Microsoft.Bot.Builder' (are you missing an assembly reference?)

I am guessing you are missing an assembly reference – TheGeneral Sep 25 '18 at 09:58 — TheGeneral, Sep 25 '18 at 09:58
and what's that assembly reference? – Dibyajit Goswami Sep 25 '18 at 11:15 — Dibyajit Goswami, Sep 25 '18 at 11:15

There is a specific package for the Dialogs which is does not come with Microsoft.Bot.Builder even though it is the same namespace. You need to install the package Microsoft.Bot.Builder.Dialogs linked here and add that to your using statements. That ought to get rid of your error.

Using Package Manager Install-Package Microsoft.Bot.Builder.Dialogs

Using .NET CLI (for dotnet core) dotnet add package Microsoft.Bot.Builder.Dialogs

With the help of the google machine, i have figured you are probably jsut needing

Microsoft.Bot.Builder.Dialogs

Disclaimer , after looking around for resources and documentation on this, i have managed to find none to show the available SDK nugets

Its like they want to keep it a secret

its not like that, I'm developing a chat bot which is having all the classes required for it from the Microsoft.Bot.Builder so it is not viable to use just that, though I have tried. – Dibyajit Goswami Sep 25 '18 at 11:14

Finally I found, they got problem with .net standard and latest bot-package update. Use stable bot-package version 3.15.2, no need to update all, just update other things except bot related reference. The Problem is going to solve.

You need to use the .NET framework version >=4.6. This error is faced when .net framework is 4.5. Microsoft.Bot.Builder version 3.8.0 works with it.
