InPlaceHostingManager Hosted in IIS, Access is denied error - iis

Question

I am using the InPlaceHostingManager class to integrate the manifest file for some click once applications hosted in IIS, I am trying to get the version number. See code below
try
{
iphm = new InPlaceHostingManager(new Uri(deployManifestUriStr), false);
iphm.GetManifestCompleted += new EventHandler<GetManifestCompletedEventArgs>(iphm_GetManifestCompleted);
iphm.GetManifestAsync();
}
catch (UriFormatException uriEx)
{
this._logger.Fatal(uriEx, $"Unable to load Applicaition Versions (Invalid Uri) for uri : {deployManifestUriStr}");
}
catch (PlatformNotSupportedException platformEx)
{
this._logger.Fatal(platformEx, $"Unable to load Applicaition Versions (Platform Not Supported Exception) for uri : {deployManifestUriStr}");
}
catch (ArgumentException argumentEx)
{
this._logger.Fatal(argumentEx, $"Unable to load Applicaition Versions (Argument Exception) for uri : {deployManifestUriStr}");
}
catch (UnauthorizedAccessException ex)
{
this._logger.Fatal(ex);
this._logger.Fatal(ex.InnerException);
this._logger.Fatal(ex, $"Unable to load Applicaition Versions (Unauthorized Access Exception) for uri: {deployManifestUriStr}");
}
catch (Exception ex)
{
this._logger.Fatal(ex, $"Unable to load Applicaition Versions (Exception) for uri : {deployManifestUriStr}");
}
I am getting the following error
System.UnauthorizedAccessException: Access to the path 'Deployment' is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

The applicaition pool is running as network service. Does anyone know where the Deployment folder is?

Answer 1

I had a look inside InPlaceHostingManager > DeploymentManager > SubscriptionStore > Get_CurrentUser (CurrentUSer) I Found the following
public static SubscriptionStore CurrentUser
{
get
{
if (_userStore == null)
{
lock (_currentUserLock)
{
if (_userStore == null)
{
string folderPath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
string deployPath = Path.Combine(folderPath, "Deployment");
string tempPath = Path.Combine(Path.GetTempPath(), "Deployment");
_userStore = new SubscriptionStore(deployPath, tempPath, ComponentStoreType.UserStore);
}
}
}
return _userStore;
}
}
After copying the code to some where I could debug it, I found the following.
string folderPath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
The above line returns nothing. This lead me to the following

This change fixed it for me
Open your %WINDIR%\System32\inetsrv\config\applicationHost.config and look for <applicationPoolDefaults>. Under <processModel>, make sure you have the following attributes loadUserProfile="true" setProfileEnvironment="true"

You can use Process Monitor to see which is the Deployment folder.
About how to use the Process Monitor you can refer to this link:
