TFS Service Unavailable – HTTP Error 503. The service is unavailable.

by Xavier Dilip Kumar 20. September 2013 07:32


The TFS 2010 web access url reported "Service Unavailable – HTTP Error 503. The service is unavailable.", but I was able to access TFS 2010 using Visual Studio IDE and other clients. Only the TFS web was not working


Verify whether The "Microsoft Team Foundation Server Web Access Application Pool" is running. If not, start the app pool.

SharePoint Client-Side Object Model ClientContext.Load method cannot be loaded.

by Xavier Dilip Kumar 11. September 2013 11:59


'Microsoft.SharePoint.Client.ClientContext' does not contain a definition for 'Load' and no extension method 'Load' accepting a first argument of type 'Microsoft.SharePoint.Client.ClientContext' could be found (are you missing a using directive or an assembly reference)


I got the above exception while using 'Microsoft.SharePoint.Client.ClientContext' load method in my share point web part project. Adding Microsoft.SharePoint.Client.Runtime.dll to project assembly references resolved the errors. The reason for the load method error is as follows

  • ClientContext inherits from ClientRuntimeContext
  • ClientContext is defined in Microsoft.SharePoint.Client.dll
  • ClientRuntimeContext is defined in Microsoft.SharePoint.Client.Runtime.dll
  • ClientRuntimeContext defines the Load method


Add Microsoft.SharePoint.Client.Runtime.dll along with Microsoft.SharePoint.Client.dll to project assembly references.
