I am getting the following error when I run a project:

Severity Code Description Project File Line Suppression State
Warning Assembly 'F:\SiTechMasterBase1.0\ItemMaster 4.0\obj\Debug\TempPE\My Project.Resources.Designer.vb.dll' has mismatched identity 'My Project.Resources.Designer.vb.dll', expected file name: 'My Project.Resources.Designer.vb.dll.dll'. MasterBase 0.1


I have looked up information on this and it suggests that I change the file name to match that. However, I am very hesitant to do anything, as this is into an area where I am completely ignorant and, other than the error showing up in the error window, nothing is occurring that I know of. Bottom line is I am afraid of unintended consequences and would like it if someone might explain to me what is going on and maybe a little support to going ahead and doing as the information suggests I do. Also, why would/should there be a .dll.dll file? That does not even make sense to me.
