I've built a Windows service as “Any CPU”. Why does it run in 32-bit mode on my 64 bit machine? [duplicate]

Answer 1

In case anybody runs across the same thing I did: I had created two new config settings (copied from the Debug config). For some reason "Prefer32Bit" flag was set to true, even though the checkbox was greyed out and unchecked in the project config page.

You can fix it by removing the line directly from the .csproj file.

  
    true
    bin\Staging\
    DEBUG;TRACE
    full
    AnyCPU
    prompt
    MinimumRecommendedRules.ruleset
    true
