Aspx designer cs not updating

When VS2013 was tied to TFS (I am not sure of the version, perhaps 2010 was in the previous report) and the Environment was selected, VS would not update the designed files.

Then I don't get any errors in design mode until I close the project and open it again. NET guidelines and best practices for dll creation. Can you please try the suggestions provided in Unknown server tag/Could not load file or assembly errors section in this help article? Hi Anders, First, since this is isolated to a certain machine, I would advise comparing some settings/installed software, especially VS plugins to try and find a difference.We often use files in our projects to create xsd (XSD: XML Schema Definition, used to validate XML) schema.However, sometimes when we attempt to update the dataset the Visual Basic/ C-Sharp code behind the scene does not get updated i.e., dataset.or dataset.does not get updated.The issues are - I have a Ribbon Bar control in an that gets deleted from the each time I save the file.I "solved" this moving the control declaration in my file - I have several pages hosting different Telerik controls which definition in the files has the case of the tag in the file.
