To fix this issue you need to rename the conflicting classes.

To find out the conflicting classes follow these steps:

- From Visual Studio Tools Menu Click Options.
- Expand Projects and Solutions
- Click on Build and Run
- From the dropdown "MSBuild Project Build Output Verbosity" select Diagnostic
- Click on OK to save
- Now build your project using the Web Deployment Project
- Now wait for the project build to fail.
- From the Visual Studio View Menu click on Output You will see where the duplicates on output when it fails to build. Fix the duplicates.
- Build again.
