Aspnetcore: Inprocess application start problem

[aurokk]

Hello!
I'm trying to host web app using inprocess hosting model. And...
Application can't start.
IIS responses with 500.30.
ANCM logs contains this.
If i switch hostingModel to OutOfProcess — everything is ok.

My web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath=".\Dodo.ClientSite.exe" arguments="" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false" hostingModel="InProcess">

         <handlerSettings>
                  <handlerSetting name="debugFile" value=".\aspnetcore-debug.log" />
                  <handlerSetting name="debugLevel" value="FILE,TRACE" />
              </handlerSettings>
      </aspNetCore>
   </system.webServer>

Your Program.Main is throwing an exception. It's probably due to the CurrentDirectory issue: #4206. Here is our recommended workaround for now: https://github.com/aspnet/Docs/blob/master/aspnetcore/host-and-deploy/aspnet-core-module/samples_snapshot/2.x/CurrentDirectoryHelpers.cs. This will be fixed in a patch.

I assume the workaround has resolved your issue. Feel free to reopen otherwise.

I'm having problems applying the suggested fix and resolving the issue which I don't know if it should be fixed in the current version .Net Core 2.2 since I am still getting the same error - IIS responses with 500.30 - when running InProcess. Enabling the logs I could see the problem is related to the same issue as the directory returned is not the correct directory. Instead, it returned the path where the IIS service run from in the system. To apply the fix, I've copied the CurrentDirectoryHelper.cs to my project and call it from the Program.cs before Setting the SetBasePath,

logger.LogWarning($"Applying Patch to fix Current Directory issue. Current Directory: {Environment.CurrentDirectory}"); //TODO: the line below can be removed when the bug with InProcess method is fixed (more details, follow the class definition and read the comments) CurrentDirectoryHelpers.SetCurrentDirectory(); logger.LogWarning($"Fix applied. Current Directory now is: {Environment.CurrentDirectory}");
Applying the fix as such still produces the same result.
The Application starts fine if running as OutOfProcess and if running under IIS Express

Can anyone help me with this, please?
