Cannot Remove Reference from Web Site Project in Visual Studio 2008
I just ran into an issue where I right-clicked a Web Site Project in Visual Studio 2008 and chose Property Pages and then tried to remove a reference. However, whenever I clicked the Remove button the dialog just flashed and the reference remained.
The issue turned out to be that the web.config file (where the reference information is stored) was read-only. Making the file read-write again solved the issue.
