SharePoint Online CSOM for creating Site Collection App Catalog

VesaJuvonen 

Hi,

i am facing similar problem, i need to create tenant app catalog site by code (CSOM for my case).

Your solution works if that site exists and adds particular existing site as an app catalog site.

Web.TenantAppCatalog.SiteCollectionAppCatalogsSites.Add(this.Site.Url);

But i need to create tenant app catalog site and i couldn't find any solution to do that by any api. Is there a solution for that?

I confirm that below code works as expected. I used SharePoint App credentials which has permissions on tenant to execute the code and its working as expected. 

Thanks Vesa!

using (ClientContext clientContext = authManager.GetClientContextWithAccessToken(siteURL))
            {
                try
                {
                    clientContext.Load(clientContext.Web);
                    clientContext.ExecuteQuery();
                                       clientContext.Web.TenantAppCatalog.SiteCollectionAppCatalogsSites.Add(siteURL);
                    clientContext.Web.Update();
                    clientContext.ExecuteQuery();
                }
                catch (Exception ex)
                {

                    Console.WriteLine("Exception: " + ex.ToString());
                }
                

            }

Thanks Vesa! I will give a try and update you if it helps.
