The type or namespace name 'MsgChannelUtilities' does not exist in the namespace 'Terrasoft.Configuration' (are you missing an assembly reference?)

Hi all,

I've tried to send a message from business process to frontend (freedom ui). However, every time got an error "The type or namespace name 'MsgChannelUtilities' does not exist in the namespace 'Terrasoft.Configuration' (are you missing an assembly reference?)".

I tried in different ways:

var userConnection = Get("UserConnection");

Terrasoft.Configuration.MsgChannelUtilities.PostMessage(userConnection, message, UserConnection.CurrentUser.Id);

AND

Terrasoft.Configuration.MsgChannelUtilities.PostMessageToAll(message, UserConnection.CurrentUser.Id);

AND ALSO

MsgChannelUtilities.PostMessage(userConnection, message, UserConnection.CurrentUser.Id);

I added usings Terrasoft.Configuration and Terrasoft.Configuration.MsgChannelUtilities to my BP but still, it doesn't work.

I found this issue in CRM trial version 8.1.1.3635.

Does anyone have any suggestions? Maybe there are some other ways to send and process the message?
