Powershell not compiling c# code into .exe

Question

I have some code that is not compiling to an .exe file in PowerShell,

  $csharp = '#CSharp code goes here'
  $tmpFile = [IO.Path]::GetTempFileName() + ".cs" # Creates Temp file
  Out-file -FilePath $tmpFile -InputObject $csharp # sets content
  Start-Process -FilePath C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe -ArgumentList "/out:Launcher.exe" # Starts csc

When the script loads there is a popup with csc.exe that closes within milliseconds. Could anyone help? Thanks, CollinScripter

Answer 1

To prevent the new window from appearing you can use the NoNewWindow switch:

Start-Process -FilePath C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe -NoNewWindow -ArgumentList "/out:Launcher.exe"

Note your current command is not passing the source file to compile.

Answer 2

Works better once you add an input. I generated a fatal error CS2008: No inputs specified with your snippet.

  $csharp = '#CSharp code goes here'
  $tmpFile = [IO.Path]::GetTempFileName() + ".cs" # Creates Temp file
  Out-file -FilePath $tmpFile -InputObject $csharp # sets content

Start-Process -FilePath C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe -ArgumentList "/addmodule:$tmpFile /out:Launcher.exe" # Starts csc
