I installed VisualSVN Server 2.5.4. I can create user and repository. My question is how can I create/delete user/repository from C#. Is there any library?

There is no need to write custom WMI scripts anymore; PowerShell cmdlets available beginning with VisualSVN Server 3.4 cover the most Subversion server administration and repositories management use cases. Read about the new feature at https://www.visualsvn.com/server/features/powershell/

VisualSVN Server 3.4 introduces PowerShell module that provides you with a number of helpful cmdlets. The cmdlets can be used for administering VisualSVN Server and its repositories either locally or remotely. Here is the complete reference on VisualSVN Server PowerShell cmdlets.

For example,

• You can create a new repository MySuperRepo by running this PowerShell command:

  New-SvnReposiory MySuperRepo

• You can create a project structure in the repository

  New-SvnRepositoryItem MySuperRepo -Path /branches, /tags, /trunk -Type Folder

• You can provide DOMAINDevelopers Active Directory group account with Read / Write access to the new repository

  Add-SvnAccessRule MyRepo -Path / -AccountName DOMAINDevelopers -Access ReadWrite

• You can calculate the size the repository takes on disk:

  Measure-SvnRepository MySuperRepo

• You can verify the repository for corruptions:

  Test-SvnRepository MySuperRepo

  And much, much more!

For more information and the complete list of cmdlets, read the article VisualSVN Server PowerShell Cmdlet Reference.

VisualSVN Server can be managed via WMI (Windows Management Instrumentation) interface.

MOF file which describes the VisualSVN Server interface resides in the %VISUALSVN_SERVER%WMI on the computer where VisualSVN Server is installed. Using this file as a reference you can write a C# script to manage VisualSVN Server.

Please check the MSDN article: http://msdn.microsoft.com/en-us/library/bb404655

I'm including the following samples for your reference:

• This C# code will create a Subversion user 'user1' with password 'secret'.

      ManagementClass userClass = new ManagementClass("root\VisualSVN", "VisualSVN_User", null);
  
      // Obtain in-parameters for the method
      ManagementBaseObject inParams =
          userClass.GetMethodParameters("Create");
  
      // Add the input parameters.
      inParams["Name"] = "user1";
      inParams["Password"] = "secret";
  
      // Execute the method and obtain the return values.
      ManagementBaseObject outParams =
          userClass.InvokeMethod("Create", inParams, null);
  

• This C# code will create a new repository 'Repo1'.

      ManagementClass repoClass = new ManagementClass("root\VisualSVN", "VisualSVN_Repository", null);
  
      // Obtain in-parameters for the method
      ManagementBaseObject inParams =
          repoClass.GetMethodParameters("Create");
  
      // Add the input parameters.
      inParams["Name"] = "Repo1";
  
      // Execute the method and obtain the return values.
      ManagementBaseObject outParams =
          repoClass.InvokeMethod("Create", inParams, null);
  

• This C# code will provide SID S-1-5-32-545 ('BUILTINUsers') with Read / Write access to repository 'Test'. FYI: The AccessLevel values are as described in the MOF: "0 - no access, 1 - read only, 2 - read/write".

  ManagementClass userClass = new ManagementClass("root\VisualSVN", "VisualSVN_WindowsAccount", null);                            
  ManagementClass authzClass = new ManagementClass("root\VisualSVN", "VisualSVN_SecurityDescriptor", null);
  ManagementClass permClass = new ManagementClass("root\VisualSVN", "VisualSVN_PermissionEntry", null);
  
  ManagementObject userObject = userClass.CreateInstance();
  userObject.SetPropertyValue("SID", "S-1-5-32-545");
  
  ManagementObject permObject = permClass.CreateInstance();
  permObject.SetPropertyValue("Account", userObject);
  permObject.SetPropertyValue("AccessLevel", 2);
  
  ManagementObject repo = new ManagementObject("VisualSVN_Repository.Name='Test'");
  
  ManagementBaseObject inParams =
      authzClass.GetMethodParameters("SetSecurity");
  
  inParams["Object"] = repo;
  inParams["Permissions"] = new object[] { permObject };
  
  ManagementBaseObject outParams =
      authzClass.InvokeMethod("SetSecurity", inParams, null);

Updated on 02/10/2013:

WMI schema has been changed (and improved!) in VisualSVN Server 2.6. In short, to set access permissions on a repository path, you are required to:

• create VisualSVN_Repository class object specifying repository name,
• create VisualSVN_PermissionEntry entry object specifying account username and access permissions,

• invoke SetSecurity method on VisualSVN_Repository passing valid repository path and PermissionEntry object.

      ManagementClass userClass = new ManagementClass("root\VisualSVN", "VisualSVN_WindowsAccount", null);
      ManagementClass permClass = new ManagementClass("root\VisualSVN", "VisualSVN_PermissionEntry", null);
      ManagementClass repoClass = new ManagementClass("root\VisualSVN", "VisualSVN_Repository", null);
  
      ManagementObject userObject = userClass.CreateInstance();
      userObject.SetPropertyValue("SID", "S-1-5-32-545");
  
      ManagementObject permObject = permClass.CreateInstance();
      permObject.SetPropertyValue("Account", userObject);
      permObject.SetPropertyValue("AccessLevel", 2);
  
      ManagementObject repoObject = repoClass.CreateInstance();
      repoObject.SetPropertyValue("Name", "MyProject");
  
      ManagementBaseObject inParams =
          repoClass.GetMethodParameters("SetSecurity");
  
      inParams["Path"] = "/trunk";
      inParams["Permissions"] = new object[] { permObject };
  
      ManagementBaseObject outParams =
          repoObject.InvokeMethod("SetSecurity", inParams, null);
