Answer 1

I had to set it in the project properties otherwise it just kept resetting my web.config changes

Answer 2

I changed the specification in Web.config to run out of process. Originally the specification was for InProcess as follows:

  <aspNetCore processPath="dotnet" arguments=".\Cashflow.dll" stdoutLogEnabled="false" hostingModel="InProcess" stdoutLogFile=".\logs\stdout">

I changed this to OutOfProcess:

  <aspNetCore processPath="dotnet" arguments=".\Cashflow.dll" stdoutLogEnabled="false" hostingModel="OutOfProcess" stdoutLogFile=".\logs\stdout">

and Bingo! The application runs as expected.

Can anyone explain why?
