When troubleshooting Sitecore issues and interacting with support there is often a need to confirm the versions of binaries in your solution. While there are tools to help provide all the information, sometimes its just not possible in some environments.

One particular issue we had required a detailed list of the bin folder. Handily the sitecore does write details of all the binaries at startup to the log. Un-handily, if you’re using Application Insights, you’ll likely have the log message truncated as it tends to exceed the 10,000 character trace message size limit.

Unfortunately it’s not as easy as just dir *.dll, as the details required include assembly names and version. But, powershell to the rescue.

get-childitem .\bin\* -include *.dll
| foreach-object { "{0}`t({1},{2})" -f $_, [System.Diagnostics.FileVersionInfo]::GetVersionInfo($_).Comments, [System.Diagnostics.FileVersionInfo]::GetVersionInfo($_).ProductVersion }
| Out-File -filepath assemblies.txt

This will dump the binary details out to a file in the same format as the Sitecore log would’ve done. If you’re on Azure Web apps, you can run this via the powershell console in KUDU. This file can then easily be downloaded then analysed, compared or submitted to support.
