I have following error :

The item \xxx\yyy.cs“ was specified more than once in the ”Sources“ parameter. Duplicate items are not supported by the ”Sources" parameter

this is an mvc web application. I have read many blogs and articles which are relevant to this but does not find any solution. i have checked in .csproj and does not find any duplicate entries for file in .csproj file.

Hi Karan,
Follow below steps

1. Just copy the .cs file and paste in other directory for back up purpose.
2. Delete that file from VisualStudio solution. Then clean the solution.
3. Restart visual studio.
4. Check whether you are getting same error.

or

Open corresponding *.csproj file -> search the word "yyy.cs" and see how many times it contains. If it contains more than once then delete one of them(be careful when delete because it may affect the project if wrongly deleted).

Please go through below link:
