Introduction
 
In this article, you will learn how to create a Wiki page on SharePoint Online site with various methods, using PnP Core CSOM library.
 
The main advantage of using PnP Core libraries is the reduced code to get/set the required information. The required object can be retrieved/created/updated with a very small piece of code, once the client context is set.
 
Prerequisite
  • PnP Core CSOM documentation can be found on the official site here.
  • PnP Core CSOM library packages can be downloaded here. 
The code, given below, is being tested, using Visual Studio console application. Once the console application is created, the packages can be installed, using "Install-Package SharePointPnPCoreOnline" command on Package Manager console of Visual Studio. Once installed, the references and packages will be imported to the solution.
 
The references used in the sample are given below.
  • Microsoft.SharePoint.Client
  • OfficeDevPnP.Core 
Connect to SharePoint Online site
 
The Authentication Manager is used to retrieve the client context of the site. To connect to SharePoint Online site, the token, given below is used.
  • GetSharePointOnlineAuthenticatedContextToken 
The parameters required are.
  • SharePoint Online site URL
  • Tenant UserId
  • Tenant Password (or secured string)

  5.   
  6. AuthenticationManager authManager = new AuthenticationManager();  
  7. try  
  8. {  
  9.     using (var clientContext = authManager.GetSharePointOnlineAuthenticatedContextTenant(siteUrl, userName, password))  
  10.     {  
  11.   
  12.         // Input Parameters  
  13.         string libraryName = "WikiPages";  
  14.         string pageName = "TestPage.aspx";  
  15.   
  16.         // Creating Wiki Page

  2. string siteUrl = "https://abc.sharepoint.com/";  
  3. string userName = "[email protected]";  
  4. string password = "***";  
  5.   
  6. AuthenticationManager authManager = new AuthenticationManager();  
  7. try  
  8. {  
  9.     using (var clientContext = authManager.GetSharePointOnlineAuthenticatedContextTenant(siteUrl, userName, password))  
  10.     {  
  11.   
  12.         // Input Parameters  
  13.         string pageContent = "<div>Test page for PnP Core components learning</div>";
