Synchronize Dynamics CRM customizations to TFS Source Control


 

Context

A common problematic encountered in complex development projects is to handle CRM customizations in the same way that we manage other sources (plugin classes, javascript webresources, …).
Source control integration provides the following advantages:

  • Backup : Capability to restore all your CRM customizations
  • Versioning : Capability to get a previous version
  • Comparison : Capability to visualize différences
  • History : Capability to track modifications

3 years ago, I’ve worked with Tanguy Touzard on a batch that call differents applications in order to store a CRM solution to the TFS Source Control.
And, recently, I‘ve decided to rewritte it in order to optimize the process, minimize external applications dependencies and invoke CRM and TFS apis directly from Powershell.

This script use SolutionPackager application to explode CRM customization XML file into structured file and folder tree.

Prerequisites

The script couldn’t run properly without the following criterias:

  1. User who execute the script need to be :
    1. local admin (eventlog creation and write)
    2. contributor on target TFS project
  2. CRM user specified in configuration file need to be system administrator (publih, solution export)
  3. You should provide an Assembliesfolder that contains
    1. CRM SDK assemblies :
      1. Microsoft.Xrm.Sdk.dll
      2. Microsoft.Xrm.Client.dll
      3. Microsoft.Crm.Sdk.Proxy.dll
    2. SolutionPackager.exe
  4. Script must be run with elevated privileges

Process

The Powershell script realizes the following operations:

  1. Eventlog initialization to store process information or errors
  2. Load TFS SDK
  3. Load CRM SDK
  4. Load configuration file
  5. For each synch item
    1. Connect to TFS
    2. Connect to CRM
    3. Publish customization
    4. For each solution
      1. Export solution
      2. Unpack solution into TFS workspace folder
      3. Checkin modifications to TFS

All processing informations or errors are stored into a dedicated log.

Configuration

This script is based on a configuration file that allow to indicate differents CRM organizations, CRM solutions, TFS Project Collections

Each SyncItem represent a synchonization between CRM and TFS.

  • OutputPath : Temporary folder where exported CRM solution is stored
  • CRM > ConnectionString : Connection to CRM organization (More info : https://msdn.microsoft.com/en-us/library/gg695810.aspx)
  • CRM > Solutions > Solution > Name : Unique name of the CRM solution to export
  • TFS > CollectionUrl : Url of the target project collection
  • TFS > WorkspaceFolder : Path to the local TFS folder

Usage

The script could be run manually or triggered by a windows scheduled task (More info : http://blogs.technet.com/b/heyscriptingguy/archive/2012/08/11/weekend-scripter-use-the-windows-task-scheduler-to-run-a-windows-powershell-script.aspx)

You could also run it with Azure Automation or a TFS build, but you need to host the TFS and CRM SDK assemblies in a centralized storage.

 

Have fun!
