Invoke an exe from PowerShell and get feedback on success or failure

powershell

Solution

Have you tried using the `$LASTEXITCODE` variable? It will contain the exit code of the last .exe that was invoked.

Problem

How can I run an executable in PowerShell and through an if statement determine whether it succeeded or failed? More specifically I'm trying to get devenv.exe to build a solution from a PowerShell script and I need to know whether it succeeded or failed. By failed, I mean that the build has failed and I'm assuming devenv is sending something out to the shell (possibly in the `stderr` stream?) I tried using `&`, `Invoke-Expression` and `Invoke-Item` and managed to get all of them to run the exe. But I was never able to get feedback on success / failures.
