Compiler executable file csc.exe cannot be found

I am trying to use the Visual FoxPro LPX with the OleDb driver. It tests out OK, but when I try to expand the connection and it starts to build the necessary tables and such, it generates the error. I can see from monitoring LINQPad with procmon from Sysinternals that it enumerates all the FoxPro tables. It looks like it is bombing out after querying the HKLM\SOFTWARE\WOW6432Node\Microsoft\MSBuild\ToolsVersions\3.5 registry key - which does not exist on this Win10 box. Instead of 3.5 I have a 4.0 and 14.0 keys. I am running LINQPad v5.10. I can also see that LINQPad is generating a couple of temp .cs and .cmdline files... but it deletes them before I have a chance to inspect their contents.

Other connections do still work just fine. Do I just need to install .NET 3.5 on this computer to make this connection work?

Here is the relevant bits from the logs:
