xcopy is not recognized as an internal or external command, operable program or batch file

Question

I have a problem using \'xcopy\' command.

I\'m building a C# project with msbuild. At the end of the build, a batch file is called to copy my assemblies from Debug/R

Answer 1

It happened to me after I updated one of my Visual Studio extensions, during which Visual Studio was closed and reopened by the updater. I could no longer properly build my project. I closed Visual Studio and reopened it and the problem went away.
