How to get server information in CSOM?

Question

How to get SharePoint server information in CSOM function call? For instance, version of SharePoint server, to which we connected, build number, maybe other technical information. Silly enough, I cannot find relevant function or answer. Thank you.

You can retreive that information from the Microsoft.SharePoint.Client.ClientContext class such as the following.

Basic Information

$context = New-Object Microsoft.SharePoint.Client.ClientContext($siteUrl);

#SharePoint Online authentication
$context.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, (ConvertTo-SecureString $password -AsPlainText -Force));

#SharePoint On-Premise authentication
#$context.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials;

$context.ExecuteQuery();

$context.ServerVersion;    
$context.ServerSchemaVersion;
$context.ServerLibraryVersion;
$context.RequestSchemaVersion;
  

Tenant Information

If you are using SharePoint Online or On-premise multi-tenancy mode (with Admin Tenant Stub installed guide here) by using the assembly Microsoft.Online.SharePoint.Client.Tenant.dll and the class Microsoft.Online.SharePoint.TenantAdministration.Tenant

$context = New-Object Microsoft.SharePoint.Client.ClientContext($siteUrl);

#SharePoint Online authentication
$context.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, (ConvertTo-SecureString $password -AsPlainText -Force));

#SharePoint On-Premise authentication
#$context.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials;

$tenant = New-object Microsoft.Online.SharePoint.TenantAdministration.Tenant($context);

$context.ExecuteQuery();

$tenant.CompatibilityRange;
$tenant.DisplayStartASiteOption;
$tenant.ExternalServicesEnabled;
$tenant.NoAccessRedirectUrl;
$tenant.ResourceQuota;
$tenant.ResourceQuotaAllocated;
$tenant.RootSiteUrl;
$tenant.SharingCapability;
$tenant.StartASiteFormUrl;
$tenant.StorageQuota;
$tenant.StorageQuotaAllocated;

Hope it would help you.
