I tried to add all contacts obtained from a search to a marketing list.
The CRM returns a error.
I saw the event viewer and I found this warning:
Could not load type 'Microsoft.Crm.Sdk.Messages.AddMembersByFetchXmlListRequest' from assembly 'Microsoft.Crm.Sdk.Proxy, Version=18.104.22.168, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
I have a dev environment and there the system run without error.
Is there an error about dll registration?
Did this functionality work previous without any issue? Was any rollup installed recently?
Check if you are able add a single or two contacts at a time to a marketing list.
Is this happening only with contact entity or with other entities too?
It's the first time that I use this function.
If I add members using check box, I can add them without problems.
The problem is only when I add all contacts obtained from a search.
