.NET Framework NGEN v4.0.30319_x86 service will not start - Normal?

    Question

  • I'm troubleshooting an item I'm not sure is an issue, but the "Microsoft .NET Framework NGEN v4.0.30319_X86" service will not start.  Does the service need to run, can it be set to "manual" and still support .NET4.  Is there something that needs to be registered?  I ran the validaion tool against the .NET4 full version, and this is the output:

  • Hi Troyboy14k,

    Thank you for your post.

    NGEN stands for "Native Image Generation". It is a tool that improves the performance of managed applications.
    For your concern, I would suggest you to read the following two helpful links to understand NGEN.
    Please see:
    http://msdn.microsoft.com/en-us/magazine/cc163610.aspx
    http://msdn.microsoft.com/en-us/library/6t9t5wcf.aspx

    I noticed that you have tried the Verification Tool to check the installation of .NET Framework 4.0 on your machine. What's the result? You can find the verification result from "Current Status" after you run the tool.

    If .NET Framework can be verified successfully, it means that it is well installed on your machine.

    Hope this helps! If you have any concern, please feel free to let me know.

    Best regards,

  • I think he's was having the same issue I'm having.

    This service was installed in a recent auto update on my SBS 2003 server and it was installed with automatic startup.  But it just starts up and shuts right back down.  The same occurs on my XP dev machines.

    Because of that my daily server report is showing:

    Auto-started Services Not Running
    Service Name Microsoft .NET Framework NGEN v4.0.30319_X86
    Total auto-started services not running: 1
    In normal conditions, these services should be running.
    For details, it is recommended that you review errors in the
    Event log related to the service.

     

    It's a annoyance to have that in the daily server reports.  (I want to see all green items)

    Since starting up and immediately shutting down, appears to be the normal behavior for this service. (That's also what it does on XP. And the .net 4 full installation verifies as being OK.)

    Would there be a downside if we turned that service to manual startup is the question?
