ASP.NET Core The system cannot find the file specified

I have followed this tutorial on getting angular and ASP.NET Core running together. The initial build worked fine but after updating angular packages I am receiving the following error on startup of the application(I also had to reinstall nodejs in the process, not sure if this is related):

The error is on the following line:

app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions {
    HotModuleReplacement = true
});

enter image description here

enter image description here

The error itself does not provide me with any usefull information to track down the issue.

I get a:

System.AggregateException => Count = error CS0103: The name 'InnerExceptionCount' does not exist in the current context

Under InnerExceptions it lists the following error:

System.ComponentModel.Win32Exception: The system cannot find the file specified at System.Diagnostics.Process.StartCore(ProcessStartInfo startInfo) at System.Diagnostics.Process.Start() at System.Diagnostics.Process.Start(ProcessStartInfo startInfo) at Microsoft.AspNetCore.NodeServices.HostingModels.OutOfProcessNodeInstance.LaunchNodeProcess(ProcessStartInfo startInfo) at Microsoft.AspNetCore.NodeServices.HostingModels.OutOfProcessNodeInstance..ctor(String entryPointScript, String projectPath, String[] watchFileExtensions, String commandLineArguments, ILogger nodeOutputLogger, IDictionary2 environmentVars, Int32 invocationTimeoutMilliseconds, Boolean launchWithDebugging, Int32 debuggingPort) at Microsoft.AspNetCore.NodeServices.HostingModels.HttpNodeInstance..ctor(String projectPath, String[] watchFileExtensions, ILogger nodeInstanceOutputLogger, IDictionary2 environmentVars, Int32 invocationTimeoutMilliseconds, Boolean launchWithDebugging, Int32 debuggingPort, Int32 port) at Microsoft.AspNetCore.NodeServices.NodeServicesFactory.CreateNodeInstance(NodeServicesOptions options) at Microsoft.AspNetCore.NodeServices.NodeServicesFactory.<>c__DisplayClass0_0.b__0() at Microsoft.AspNetCore.NodeServices.NodeServicesImpl.CreateNewNodeInstance() at Microsoft.AspNetCore.NodeServices.NodeServicesImpl.GetOrCreateCurrentNodeInstance() at Microsoft.AspNetCore.NodeServices.NodeServicesImpl.d__10`1.MoveNext()}

If someone can point me in the direction to get more information from the Error would be helpful.

Check if you have the latest NPM installed. This solved my problem.

It looks like it is unable to find node.exe. I saw the same error after installing Node for the first time. It was because installing Node modified the system Path and the new Path wasn't getting picked up by IIS. I had to reboot my server and it was then able to find the node exe.
