Question

I have a .NET Core application. It runs locally with VS2017 and Kestrel. It runs locally under IIS. However, on the server it fails to start with a 502.5 - Process Fai

I had this problem as well and thought I'd post my solution. I'm not sure if this is intended or not, but I don't think dotnet core 2 supports Space characters in your Project Name.

I created and published a Project called "Mikes App" and when trying to run the site with IIS I would get this error (.NET Core app unable to start in IIS due to ErrorCode = '0x80004005'). When I enabled stdoutLogs through the web.config file I found the error:

No executable found matching command "dotnet-.\Mikes"

Which I found strange because the web.config file did correctly show the dll path under arguments which was ".\Mikes App.dll"

I created a new dotnet core 2 project in Visual Studio and named it "Mikes-App" instead, re-published it and updated the directory on my IIS site.

Then the site worked fine!
