My react code is stored in the "Web.Platform/Web.Client" directory and my Asp.Net Core application code is stored in "Web.Platform/Web".

app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
 {
     HotModuleReplacement = true,
     ReactHotModuleReplacement = true,
     ConfigFile = @"webpack.config.js",
     ProjectPath = @"..\Web.Client\"
});

When I run my project, I get the following error:

System.AggregateException was unhandled by user code
  HResult=-2146233088
  Message=One or more errors occurred. (Call to Node module failed with error: Error: Cannot find module '..\Web.Client\webpack.config.js'
