Description John Miller [MSFT] 2014-09-08 15:42:48 UTC

   When trying to deploy an iOS app, it can fail because the SDKs are not "in sync". There is no indication that is why, just a generic VS dialog that says there were deployment errors and that it failed. Looking in the log files, there is an error message like this:

>[08-Sep-2014 12:28:16] Error: Invalid authorization data
>[08-Sep-2014 12:28:16] Error: Unauthorized request from <ip address here>

**Steps to Reproduce:**

   1. Install an older version of the XVS plugin. 
   2. Instsller a newer version of Xamarin.iOS on the Mac build host.
   3. Build and Deploy an app.

**Actual Results:**

   It fails with no indication of why.

**Expected Results:**

   An error message that might help indicate that they are not in sync, and specify which version of Xamarin.iOS needs to be on the Mac build host. 

**Build Date & Platform:**

   XVS 3.5

**Additional Information:**

   Updating the XVS plugin to the same channel as the build host resovled the issue.

With the replacement of Build Host with XMA, this kind of versioning issue has been fixed.
Now, the missmatch between iOS versions is informed to the user as a warning when the connection is made between Windows and Mac.

Also, if there is any error during build, deployment or launch process, it's also informed to the user via Output Pane, Error list or log file, according to the case.

Mark the bug as Fixed.
