Error1:

Team Foundation services are not available from server

you may get this error  for multiple reasons and one of the reason could be that your TFS may have multiple Project Collections and your AX Team Project is not in the Default Project collection.

Solution:  make sure to include TFS Project Collection name in the TFS URL : 

http://tfs:8080/tfs/<ProjectCollectionName>

Where is Tile Button control in AX 7

Tile Button control is part of  "Application Foundation" Model. This means unless your project has a reference to this model you wouldn't be able to add this Tile button control on any form.

If you need to refer more models in your project then go through Update Model Parameters (Dynamics AX Menu)  wizard and select the models you need.
