  UseWindowsService problem

  Apr 07, 2021 03:54 PM|LArmstrong1985|LINK

  Hi,

  to transform my asp.net core in a Windows service I use function UseWindowsService() included in Microsoft.Extensions.Hosting.WindowsServices.

  All seem to works well when I install it as a service but I noticed a strange problem:  if in the appsettings.json there is a single '\' in any point of file, the service not start and return error 1053.

  I tried to update to last version of the Microsoft.Extensions.Hosting.WindowsServices (5.0.1) but the problem persists.

  Have you ever encountered this type of problem?

  The things is that if my service doesn't start due to this problem on the configuration file I can't even log on file.

  How can I solve?

  Thank you in advance!

  if the app gets a parsing error with appsettings.json it may fail to start or at the return parameter is invalid. as \ is a quote character in json, a single \ is probably an error. you probably want \\

  {
      "filename": "c:\\temp"
  }

  Hi LArmstrong1985, 

  If you have to use special character in your json string, you can escape it using \ character.

  In the rules of json, you must use \\ to escape the backslash every time.

  • Is it necessary to escape a backslash in a config file

  Best Regards,
