Compile with Visual Studio 2022?

[ED-robert]

I'm trying to compile this with Visual Studio 2022, and first I got a complaint that the "AssemblyInfo.cs" file was missing, so I removed it from the .csproj file which made it build.

However, when I run the exe using a minimal STEP file as an argument, I get the following:

Unhandled Exception: System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\data\ap203e2_mim_lf.exp'.
   at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

I'm an industrial designer and not a developer, so I'm wondering if someone who sees this could please assist?
