ASP.NET Core 2.1 IIS hosting error 502.5 - Unable to execute dotnet command to determine cause

So I am getting the rather common HTTP Error 502.5 - Process Failure now that I've hosted my project on a server VM running Windows Server 2016. While troubleshooting, I've attempted most of the solutions proposed for the same error:

ASP.NET Core 1.0 on IIS error 502.5.

Nothing else helped, so I'm looking at the answer that received the most upvotes. This mentions running the following command to receive a more meaningful message describing the error:

C:\fullpath\dotnet C:\fullpath\PROJECT.dll

I am honestly not sure how to execute that. What I did was navigate to the published project's containing folder on the server through the cmd, and issue the command like so:

dotnet .\My_Project Integration.dll

But the console prints this in response:

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

Notice how the DLL is titled 'My_Project Integration.dll, however the word 'Integration' is absent from the console response. I do not know whether the underscore is to blame here, but any help is appreciated getting the command to run.

And of course, if you know of a solution to the actual 502.5, that is welcome as well.

You've likely got this issue: https://github.com/aspnet/Home/issues/1931. The ASP.NET Core IIS Module reads the Web.config to determine what to execute to run the app.

You said running dotnet ".\My_Project Integration.dll" worked successfully and enabling stdout showed the same issue of the path being truncated after the space.

Two options:

  1. Remove the space from your project (this would be the easiest option)
  2. Update your Web.config

If you do #2, your Web.config needs to have something like this for the arguments attribute:

arguments='".\My_Project Integration.dll"'
