Solution
Open your .csproj file with a text editor (Notepad, Notepad++) Visual Studio will open it as a project.
Press Ctrl + F and search for the file of the problem. In my case the file was "Hello.txt" without commas.
Under the <ItemGroup> it resided:
<ItemGroup>
<Content Include="App_Data\NuGetBackup\yourfilename.txt" />
<Content Include="Content\admin\yourAdmin.css">
<DependentUpon>Admin.scss</DependentUpon>
</Content>
I deleted the <Content Include="App_Data\NuGetBackup\yourfilename.txt" /> line, and voila! Visual Studio allowed me to Preview before publishing!
It will end like this:
<ItemGroup>
<Content Include="Content\admin\Admin.css">
<DependentUpon>Admin.scss</DependentUpon>
</Content>
