I am trying to get a web using full url using CSOM

This one works,

var web = context.Web; context.Load(web, w => w.Webs); context.ExecuteQuery(); var subWeb = (from w in web.Webs where w.Title.Contains(accountId) select w).SingleOrDefault(); if (subWeb == null)     return false; subSite = subWeb; // this subweb works for renaming the title  return true; 

But this one doesn’t work

using(var scontext = new ClientContext(subsiteUrl)) {     scontext.AuthenticationMode = ClientAuthenticationMode.Default;     scontext.Credentials = Credentials;     scontext.ExecuteQuery();     Web sWeb = scontext.Web;     scontext.Load(sWeb, sw => sw.Title, sw => sw.Url);     scontext.ExecuteQuery();     subSite = sWeb;     return true; } 

subSite is a reference that I am passing in function parameter. This one doesn’t work for changing the title. What have I missed?
