How to set SPFolder.WelcomePage property?
Some SharePoint objects needs an instance to work perfectly, one example is here;
Sample 2 works however the Sample 1 doesn't :)
Sample1
SPSite site = new SPSite("https://server:100/sites/InternetSite/");
SPWeb web = site.OpenWeb();
web.RootFolder.WelcomePage=”TestWiki/Hello.aspx”;
web.RootFolder.Update();
Sample 2
SPSite site = new SPSite("https://server:100/sites/InternetSite/");
SPWeb web = site.OpenWeb();
SPFolder folder = web.RootFolder;
folder.WelcomePage = "TestWiki/Hello1.aspx";
folder.Update();
