New technology improvements and fixed issues in Visual Studio 2012 Update 4

Fixed issues

Note Unless otherwise indicated, linked items will take you to Microsoft Connect webpages.

Team Foundation Server
    Administration and Operations
    • Assume that you install a Team Foundation Server (TFS) 2012 application-tier server on a computer that has no instance of Microsoft SQL Server installed. You do not configure Microsoft SQL Server Reporting Services. In this situation, you cannot upgrade the application-tier server.
    • Scheduled Backups configuration is no longer blocked if the SQL Server service for TFS 2012 is running as a virtual account (for example: NT Service\MSSQLSERVER).
    • In TFS 2012 Update 2 and Update 3, transactional backups record a failure when they try to run while a full or differential backup is running.
      Scheduled Backups no longer run transactional backups if a full or differential backup is running. Instead, the job will be suspended until the other backup has finished running.
    • TFS in-place upgrades now support configuration and settings persistence together with host headers. The TFS in-place upgrades will log an error when the process encounters an invalid host header.
    • When you upgrade a configuration database to TFS 2012 Update 3, and attach a TFS collection to the upgraded configuration database, memberships and permissions may be lost.
    • When you try to upgrade TFS, the upgrade operation may be not successful and you receive the following error message:

      TF20507: The string argument contains a character that is not valid:'u0009'.
    • When you attach a TFS collection back to the upgraded TFS server, an unexpected database failure occurs and the TFS collection upgrade is not successful.
    • Assume that you use a user to move domains, and then to detach and attach a collection to an existing configuration database. When you save favorites in TFS, the favorites cannot be saved.
    • Assume that you use a user to upgrade TFS server to TFS 2012 Update 3 after a previous domain migration and display name change. The user will not be active in Work Item Tracking.
    • Assume that there are two identities that use the same domain and account name. For example:domain1\user1. In this situation,the wrong user will become activated and the user domain1\user1 cannot access to TFS collections.
    Agile Planning
    • Assume that you have a TFS 2012 instance that contains many team projects. When you open the dashboard page in TFS SharePoint portal, you experience slow performance and may receive an error message.
    • When you use Turkish locale on the computer and upload an inline image into a work item in Visual Studio 2012. The image cannot be viewed by other clients.
    • When you have a TFS 2012 server that is configured for synchronizing with Project Server, you may fail to reorder backlog items.
    Build Automation
    • Assume that you create a gated check-in for a build definition by using an upgrade template in a TFS 2010 server. You upgrade the TFS 2010 server to TFS 2012 server, and then you use the upgraded TFS server together with the TFS 2010 build agents. In this case, the build fails on the TFS 2010 build agents when you perform a check-in action.
    • Assume that you create a build definition by using the default template in a TFS 2010 server. When you upgrade the server from TFS 2010 to TFS 2012, the build definition is modified to run against a newly uploaded upgrade template.
    • 790415: Exception occurs when you call IBuildDefinition.Save method to save a build definition in a running build.
    • A "No zip file of logs was created because the archive operation failed" warning occurs when a build is completed successfully.
    • IndexSources build workflow activity experiences slow performance.
    • Assume that a scheduled build runs for a long time, and then the build is stopped manually on the next day. When you manually queue the build again, it suppresses the next scheduled build.
    • When you define a build by using Upgrade Template in file container, after you queue the build, the build starts but never completes.
    • Build may freeze on the last step and never complete, due to the failure of previous builds.
    Version Control Work Item Tracking
    • There is a 60-second delay when you use Internet Explorer to browse any page in which a work item store is used. This issue occurs if the collection contains more than 175 team projects.
    • The functionality to create or edit work items stops working if a team is associated with many area paths.
    • The functionality to move items in the Kanban board does not work in some environments that have mixed cultures.
    • When a query is saved together with an Assigned to field that contains a constant, users will not see the correct query results after saving and running the query if the constant is also a TFS group display name.
    • Assume that you have a TFS 2012 server plugin that raises an exception (For example,, during work item save), a generic AJAX exception is shown to the user instead of the exception actually thrown by the plugin.
    • A TFS user from a group that does not have work item write permission on an area can change the area of a work item to another area where he has the write permission.
    • When you delete a team project, you may receive the following error message when you perform create, read, update and delete operations for workitems:
      TF400013: An unexpected database error occurred. Contact your Team Foundation Server administrator. (Code: 208
      )
    • Performance improvement in Web Access for work item types that have many allowed field values.
    Web Access
    • When you try to connect to a TFS 2012 server by using a web browser together with an unexpected user agent string, you receive an internal error page instead of the requested page. Additionally, you cannot access any TFS web access pages.
    • Assume that you have a TFS 2012 server that is configured for synchronizing with Project Server. When you try to save a copied work item in TFS web access, you may receive the following error message:

      TF237165: Team Foundation could not update the work item because of a validation error on the server. This may happen because the work item type has been modified or destroyed, or you do not have permission to update the work item.
Windows Forms
  • You may receive the following error message in Windows Forms Designer:

    Collection was modified; enumeration operation may not execute
LightSwitch
