title: How to add an existing widget to Nopcommerce?
body: <p>I am really new to Nopcommerce. I have an existing plugin [A slider widget for homepage]. I was trying to add the Nop.Plugin.Widget.PromoSlider.csproj file in the Plugins directory from Visual Studio 17 but got the following error:</p>
  
  <blockquote>
    <p>The imported project
    "S(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" was
    not found. Also, tried to find
    "S(VSToolsPath)\WebApplications\Mlicrosoft.WebApplication.targets" in
    the fallback search path(s) for $(VSToolsPath) - "C:\Program
    Files(x86)\MSBuild\Microsoft\VisualStudio\v15.0" These search paths
    are defined in "C:\Users***\AppData\Local\
    Microsoft\VisualStudio\15.0_f96fcd52\devenv.exe.config". Confirm that
    the path in the  declaration is correct, and that the file
    exists on disk in one of the search paths. C:\Users****\Deskctop\
    Nop.Plugin.Widget.PromoSlider\Nop.Plugin.Widget.PromoSlider.csproj</p>

  <p>Can anyone help me fix this error?</p>
