ANCM InProcess startup failed because of invalid runtimeconfig.json [duplicate]

The application is deployed as an (32-bit, .NET Core 2.2) App Service on Azure. It works fine when using the standard AspNetCoreModule instead of the newer AspNetCoreModuleV2 that supports the InProcess hostingmodel.

When using the new InProcess hostingmodel, the actual error is

Could not find inprocess request handler. Captured output from invoking hostfxr: Invalid runtimeconfig.json [D:\home\site\wwwroot\Foo.Api.runtimeconfig.json] [D:\home\site\wwwroot\Foo.Api.runtimeconfig.dev.json]

Directory.GetCurrentDirectory() doesn't work in InProcess hosting model in ASP.NET Core 2.2. This is bug which I have reported in Github.

Alternative solution is to write a helper class called CurrentDirectoryHelpersas follows:

internal class CurrentDirectoryHelpers
{
    internal const string AspNetCoreModuleDll = "aspnetcorev2_inprocess.dll";

    [System.Runtime.InteropServices.DllImport("kernel32.dll")]
    private static extern IntPtr GetModuleHandle(string lpModuleName);

    [System.Runtime.InteropServices.DllImport(AspNetCoreModuleDll)]
    private static extern int http_get_application_properties(ref IISConfigurationData iiConfigData);

    [System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
    private struct IISConfigurationData
    {
        public IntPtr pNativeApplication;
        [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.BStr)]
        public string pwzFullApplicationPath;
        [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.BStr)]
        public string pwzVirtualApplicationPath;
        public bool fWindowsAuthEnabled;
        public bool fBasicAuthEnabled;
        public bool fAnonymousAuthEnable;
    }

    public static void SetCurrentDirectory()
    {
        try
        {
            // Check if physical path was provided by ANCM
            var sitePhysicalPath = Environment.GetEnvironmentVariable("ASPNETCORE_IIS_PHYSICAL_PATH");
            if (string.IsNullOrEmpty(sitePhysicalPath))
            {
                // Skip if not running ANCM InProcess
                if (GetModuleHandle(AspNetCoreModuleDll) == IntPtr.Zero)
                {
                    return;
                }

                IISConfigurationData configurationData = default(IISConfigurationData);
                if (http_get_application_properties(ref configurationData) != 0)
                {
                    return;
                }

                sitePhysicalPath = configurationData.pwzFullApplicationPath;
            }

            Environment.CurrentDirectory = sitePhysicalPath;
        }
        catch
        {
            // ignore
        }
    }
}

Then call the SetCurrentDirectory() of the CurrentDirectoryHelpers class as follows:

public class Program
{
    public static void Main(string[] args)
    {
        CurrentDirectoryHelpers.SetCurrentDirectory();

        Log.Logger = new LoggerConfiguration()
                .Enrich.FromLogContext()
                .ReadFrom.Configuration(Configuration)
                .WriteTo.Console()
                .CreateLogger();

        ...
    }
}

Now everything should work fine!
