The option of creating an empty project is available with Visual Studio .NET, but not with Visual C# .NET Standard Edition. We have made available a file that allows you to add an empty project in Visual C# .Net. Download and save the file emptypro.exe onto your hard disk, then double-click the file to extract the file CSharpExForEmptyProject.vsdir into the \Program Files\Microsoft Visual Studio .NET\VC#\CSharpProjects folder. The following file is available for download from the Microsoft Download Center: emptypro.exe (http://download.microsoft.com/download/MSPressPub/emptypro/1.0/NT5XP/EN-US/emptypro.exe) For additional information about how to download Microsoft Support files, click the article number below to view the article in the Microsoft Knowledge Base: Q119591 How to Obtain Microsoft Support Files from Online Services Microsoft used the most current virus detection software available on the date of posting to scan this file for viruses.
