AdaptiveCards: Incompatibility with bot framework 4.2.0+

Target Platforms

SDK Version

1.4.0

Application Name

all

Problem Description

Since BF was updated to use ANTLR 4.11.1 (in 4.2.0) it is no longer possible to use new AdaptiveCardTemplate(json) in the same project

It fails with this error:

      System.TypeInitializationException: The type initializer for 'AdaptiveCardsTemplateLexer' threw an exception.
       ---> System.MissingMethodException: Method not found: 'Antlr4.Runtime.Atn.ATN Antlr4.Runtime.Atn.ATNDeserializer.Deserialize(Char[])'.
         at AdaptiveCardsTemplateLexer..cctor()
         --- End of inner exception stack trace ---
         at AdaptiveCardsTemplateLexer..ctor(ICharStream input)
         at AdaptiveCards.Templating.AdaptiveCardTemplate..ctor(Object jsonTemplate)

No response

Card JSON

Example, but all fail:

{
    "type": "AdaptiveCard",
    "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
    "version": "1.5",
    "body": [
        {
            "type": "TextBlock",
            "text": "this doesnt work",
            "wrap": true
        }
    ]
}

Sample Code Language

C# (dotnet core)

Sample Code

I have created a repro below:

If you dotnet run, you will see:

❯ dotnet run
