When I try to call TFS 2012 warehouse control web service (WarehouseControlService.asmx) I got following error: Exception Message: Could not load file or assembly 'Microsoft.AnalysisServices, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.

Is it issue connected with the fact that I try to use tfs 2012 with ms sql 2012? Please advise how to resolve issue networked above.
