 | NUGET_UPDATEFILETIME_MAXRETRIES | Sets the number of times NuGet will attempt to retry seting the file timestamp when extracting packages when the first attempt failed. | On Windows anti-virus software might temporarily open files, preventing NuGet from changing the timestamp. NuGet uses an exponential back-off where the wait duration between attempts is `Math.Pow(2, retryNumber)`. The default max retries is 9, meaning the default total wait duration before failure will be approximately one second. |
 | NUGET_XMLDOC_MODE | Determines how assemblies XML documentation file extraction should be handled. | Supported modes are *skip* (do not extract XML documentation files), *compress* (store XML doc files as a zip archive) or *none* (default, treat XML doc files as regular files). |
 | NUGET_CERT_REVOCATION_MODE | Determines how the revocation status check of the certificate used to sign a package, is performed when a signed package is installed or restored. When not set, defaults to `online`.| Possible values *online* (default), *offline*.  Related to [NU3028](../errors-and-warnings/NU3028.md) |
