Unable to start debugging. The startup project could not be launched. VS2015

Question

I have started a new console project in VS2015. I only have this code :

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using SautinSoft;  namespace PdfParser {     class Program     {         static void Main(string[] args)         {              string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);             SautinSoft.PdfFocus f = new PdfFocus();             f.OpenPdf(@"path:\abc.pdf");              if (f.PageCount > 0)                 f.ToExcel(@"path:\abc.xls");         }     } } 

When I try to run, I get this :

Unable to start debugging. The startup project could not be launched. Verify debug settings for the startup project.

How can I fix this? Thanks.

Answer 1

After upgrading MSVC2015 to Update3, I had the same problem: instead of std::map in the Watch window display as a horrible std::_Tree<std::_Tmap_traits... etc., some plugins started to throw exceptions, some projects was not able to run in debug mode.

All was solved by deleting CurrentSettings.vssettings. It is usually located at Documents\Visual Studio 2015\Settings If not, go to `Tools -> Options -> Environment -> Import and Export Settings ' to find the location of this file.

Had this on a brand new scaffolded ASP.NET Core 1.0 web application.

Solved with restart of Visual Studio.
