Wenn trying to RetrieveMultiple

Could not load file or assembly 'PresentationFramework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

                using ServiceClient svc = new(_connectionString);
                if (svc.IsReady)
                {
                    QueryExpression query = new()
                    {
                        EntityName = "new_statproduction",
                        ColumnSet = new ColumnSet(true),
                        Criteria = new FilterExpression(),
                    };

                    EntityCollection retrieved;
                    try

                    {
                        throw ex;
                    }
                }

I cannot understand why this happens :(
Loosing lot of time to solve this issue.

There would need to be something else going on here, PresentationFramework is only used in the Login Controls and their supporting modules.

Its not used by the base connector.
could you provide more context as to what is going on if your still seeing the issue?
