  15. Question 10. Is There A Way To Pull Two Copies Of A Single Solution From Tfs 2010 For The Same User/machine?

    Answer :

    You can have multiple copies of a single solution either by having multiple branches in TFS or by setting up different workspaces.

    The branches are good for when you need to be able to check in code for both copies of the solution, and have other people work with it too.

    I use the multiple workspaces when I need to have a last good state of the code on my dev box while at the same time and still working on new features.

  20. Adv Java Interview Questions

  21. Question 13. How Does The Version Control Compare To Perforce? Branching, Merging, Change Lists Etc?

    Answer :

    Team Foundation Server supports all normally expected Source Control features such as branching, merging, exclusively locking, remote disconnected scenarios, labeling, searching on various properties high fidelity reporting (how much code churn per person per project per iteration etc) plus a couple of newer paradigms like shelving and optimization for things like branching scenarios (many version control systems do a full copy for branches). I would have some performance comparisons but most systems don’t allow this.

  23. Question 14. Why Doesn’t Source Control Detect That I Have Deleted A File/folder On My Local Disk?

    Answer :

    The main scenario here is deleting a file (by mistake or intentionally) outside of Team Foundation and then trying the get that file back from source control. If the file version has not changed the server thinks the user already has the file and does not copy it over. This is because the server keeps a list of files that the user already has and when activities are made outside of source control this list becomes out of date. Team Foundation Version Control does have a force get option which will provide the functionality needed to obtain the desired version but it is currently partially hidden under the Get Specific Version Dialog window as a check box item.

  24. Question 15. How Do I Redisplay Source Control Explorer?

    Answer :

  28. Question 17. Are Deletes You Make In Tfs 2010 Source Control Physical Or Logical? Can Accidental Deletes Be Recovered?

    Answer :

    Deletes are fully recoverable with the “undelete” operation. You wouldn’t want to do a SQL restore because that would roll back every change to the TFS in the time since the file was deleted.

  29. SQL Server Analysis Services (SSAS) Interview Questions

  30. Question 18. What Are The Different Events Available In The Event Model And Is There Any Documentation On Them?

    There is really only one SCC event and that is the one that is raised on checkin. Subscription is via the general event model that is discussed in the extensibility kit.

  31. SSIS(SQL Server Integration Services) Interview Questions

  32. Question 19. Can We Disable The “override Checkin Policy Failure” Checkbox? Can That Be Customized Based On User Login, Policy Type Of File Type?

    Answer :

    No. It is designed it to be fully auditable by including policy compliance data in the change set details and in the checkin mail that is delivered, but left it up to the developer to determine whether they have a good reason for overriding.

  33. Question 20. Can I Install The Tfs 2010 Build Service On My Tfs 2008 Build Machine?

    Answer :

  36. Question 22. Can We Configure Scc To Not Check-in The Binary Files? Where Are Such Configurations Done?

    Answer :

    Team Foundation Version Control provides a way to limit check-ins by setting up check-in policies that are evaluated before a check-in can take effect. The easiest way to do this is by authoring a policy that checks if the user is trying to check-in a binary file from a given folder structure and reject or accept it in accordance.

  37. Question 23. How Can I Add Non-solution Items To Source Control?

    Answer :

    This can be achieved by either clicking the Add icon or by going to File > Source Control and selecting the Add To Source Control menu item.

  41. Question 25. What Plugin / Extensibility Api Does It Expose?

    Answer :

    The Team Foundation Server component model for modifying both the Process Template and creating plugins is built on to be entirely open(in many cases the entry points are defined in XML configuration files). In addition to the having this the development team and community is quite active in supplying samples of this:

    • Brian Harry
    • Buck Hodges
    • Rob Caron

    This open platform has also enabled a ecosystem of add-ons like Teamlook, Teamprise, Teamplain, Teamword, TFSPermission Manager.

  42. Question 26. Any Support For Distributed Build Tools? Ex: Integrating Our Custom Data Build Tools Into The System Throughout A Network?

    Answer :

    MSbuild was written to be extensible and integrate with existing tools through easy to use XML configuration files. Many of the commercial build utilities are already using and/or integrated with MSBuild –such as In addition to making these actions part of the build script I have found the generic tests set to run as part of the build to do just as good a job with a rich user interface and support for managing/filtering etc.
