Starting an app in non-default database causes exception

[joozek78]

Starcounter.DbException: ScErrFailingEntrypoint (SCERR4259): The user code entrypoint method raised an exception. System.ArgumentException: Handler relative URI: "/useradmin\useradmin/starcounter.authorization.redirection.html" is ill formed. Please consult RFC 3986 for more information.

This is caused by this line. Application.ToString() prepends database name with a backslash, but only if database is not default. The backslash causes the exception, but illegal characters in db name could also cause trouble.

I can confirm the problem still exists:

The fix is trivial. Starcounter.Application has the following structure when started in custom database.

{
  "Host": {},
  "Name": "Playground",
  "DisplayName": "custom\\Playground",
  "FullName": "custom\\Playground",
  "FilePath": "D:\\GitHub\\Miyconst\\Playground\\Playground\\bin\\Debug\\Playground.exe",
  "WorkingDirectory": "D:\\GitHub\\Miyconst\\Playground\\Playground",
  "ResourceDirectories": [],
  "Arguments": null
}

So, this would fix the issue:

-public string RedirectionViewUri => $"/{Application.Current}/Starcounter.Authorization.Redirection.html";
+public string RedirectionViewUri => $"/{Application.Current.Name}/Starcounter.Authorization.Redirection.html";
