Hi all, I was able to successfully set up a EpiServer cms 5 website using the episerver CMS Manager. When this website is compiled using VS 2005, it throws few compilation errors. Details of which are as follows. Error 1 Could not load type 'EPiServer.UI.Admin.Languages'. d:\EpiPOC\EpiServerPOC\customUI\admin\languages.aspx 1 Error 2 Could not load type 'EPiServer.UI.Edit.SidBrowser'. d:\EpiPOC\EpiServerPOC\customUI\edit\sidbrowser.aspx 1 Error 3 Unknown server tag 'Workflow:Instances'. d:\EpiPOC\EpiServerPOC\customUI\admin\workflowdefinitionedit.aspx Am I missing any references here? Thanks in advance, Harish.
