What is the class available in SharePoint API to programmatically provision a new Managed Metadata service Application or How to provision a new Managed Metadata service application Programmatically using c#

1 Answer 1


The below code, from here, is the closest code I have seen to provision in C#, but it is missing crucial parts it feels:

private void ProvisionMetadataService()
        // We don't have the metadata service configured, so let's do that.
        var proxy = SPFarm.Local.ServiceProxies.Where(s => s.GetType().Name.Equals("MetadataWebServiceProxy")).FirstOrDefault();
        if (null == proxy)
        throw new SPException("Failed to get instance of metadata web service proxy, is it installed?");
        foreach (var proxyApp in proxy.ApplicationProxies.Where(proxyApp =>
            proxyApp.Properties["IsDefaultSiteCollectionTaxonomy"] = true;
        // Give the current user access rights to the metadata service.
        var service = SPFarm.Local.Services.Where(s => s.GetType().Name.Equals("MetadataWebService")).FirstOrDefault();
        if (null == service)
             throw new SPException("Failed to get instance of metadata web service, is it installed?");
        var serviceApp = service.Applications.OfType<SPIisWebServiceApplication>().FirstOrDefault();
        if (null == serviceApp)
             throw new SPException("Failed to get instance of metadata web service app, is it installed?");
        var security = serviceApp.GetAdministrationAccessControl();
        var cba = SPClaimProviderManager.Local;
        var claim = cba.ConvertIdentifierToClaim("DOMAIN\user",SPIdentifierTypes.WindowsSamAccountName);
        security.AddAccessRule(new SPAclAccessRule<SPCentralAdministrationRights>(claim, SPCentralAdministrationRights.FullControl));

I usually use PowerShell instead, code from here:

# Loading Microsoft.SharePoint.PowerShell
$snapin = Get-PSSnapin | Where-Object {$_.Name -eq 'Microsoft.SharePoint.Powershell'}
if ($snapin -eq $null) {
   Write-Host "Loading SharePoint Powershell Snapin"
   Add-PSSnapin "Microsoft.SharePoint.Powershell"

$ManagedAccount = Get-SPManagedAccount | select -First 1
if ($ManagedAccount -eq $null) { throw "No Managed Account" }

$ApplicationPool = Get-SPServiceApplicationPool "SharePoint Hosted Services" -ErrorAction SilentlyContinue
if ($ApplicationPool -eq $null)
   $ApplicationPool = New-SPServiceApplicationPool "SharePoint Hosted Services" -Account $ManagedAccount
   if (-not $?) { throw "Failed to create an application pool" }

Write-Progress "Creating Taxonomy Service Application" -Status "Please Wait..."

$MetadataseviceInstance = (Get-SPServiceInstance |?{$_.TypeName -eq "Managed Metadata Web Service"})
if (-not $?) { throw "Failed to find Metadata service instance" }

if ($MetadataseviceInstance.Status -eq "Disabled")
   $MetadataseviceInstance | Start-SPServiceInstance
   if (-not $?) { throw "Failed to start Metadata service instance" }

while (-not ($MetadataseviceInstance.Status -eq "Online"))
   Write-Host "Waiting for provisioning ..."; sleep 5;

$MetaDataServiceApp = New-SPMetadataServiceApplication -Name "Demo Metadata Service Application" -ApplicationPool $ApplicationPool
if (-not $?) {throw "Failed to create Metadata Service Application" }

$MetadataServiceAppProxy = New-SPMetadataServiceApplicationProxy -Name "Demo Metadata Service Application Proxy" -ServiceApplication $MetaDataServiceApp -DefaultProxyGroup

# This service application is the default storage location for Keywords.
$MetadataServiceAppProxy.Properties["IsDefaultKeywordTaxonomy"] = $false

# This service application is the default storage location for column specific term sets.
$MetadataServiceAppProxy.Properties["IsDefaultSiteCollectionTaxonomy"] = $false

# Consumes content types from the Content Type Gallery
$MetadataServiceAppProxy.Properties["IsNPContentTypeSyndicationEnabled"] = $false

# Push-down Content Type Publishing updates from the Content Type Gallery
# to sub-sites and lists using the content type.
$MetadataServiceAppProxy.Properties["IsContentTypePushdownEnabled"] = $false

  • We use New-SPMetadataServiceApplication in powershell..what is the nearest method in Sharepoint API if available??

  • There is not, as I just wrote. The first snippet above is the closest for C#, and as you can see it is already counting on a proxy Commented May 30, 2014 at 6:06
  • It is counting on proxy, but what if the actual ManagedmetaData service is not set up?? I mean it is not yer configured. We have to provide an application Pool, Database server,Database Name and those are missing.

  • Yepp, I do not think you can do that with C# Commented May 30, 2014 at 6:10
  • Creating an web application,we have the WebApplicationBuilderclass.., In the same way there should be a way to create service applications using Sharepoint APi
