# Current library Version the module expects $currentLibraryVersion = New-Object System.Version(0, 9, 1, 36) <# Library Versioning 101: The version consists of 4 segments: Major, Minor, Build, Revision Major: Should always be equal to the main version number of the dbatools PowerShell project. Minor: Tracks major features within a major release. Increment on new features or significant structural changes. Reset to 0 when incrementing the major version. Build: Tracks lesser functionality upgrades. Increment on all minor upgrades, reset to 0 when introducing a new major feature or major version. Revision: Tracks all changes. Every single update to the library - bugfix, feature or redesign - increments the revision counter. It is never reset to 0. Updating the library version number: When changing the library version number, it is necessary to do so in TWO places: - At the top of this very library.ps1 - Within AssemblyInfo.cs These two locations MUST have matching version numbers, otherwise it will keep building the library and complaining about version mismatch! #> <# #---------------------------------# # Runtime configuration variables # #---------------------------------# The library recognizes a few external variables in order to customize its behavior on import. $dbatools_strictsecuritymode Setting this to $true will cause dbatools to always load the library directly from the module directory. This is more secure, but less convenient when it comes to updating the module, as all consoles using it must be closed. $dbatools_alwaysbuildlibrary Setting this to $true will cause the module to always build the library from source, rather than reuse the binaries.

Generally, when something goes wrong we try to handle and interpret in an understandable manner. Unfortunately, something went awry with importing our main library, so all the systems making this possible would not be initialized yet. We have taken great pains to avoid this issue but this notification indicates we have failed. Please, in order to help us prevent this from happening again, visit us at: https://github.com/sqlcollaborative/dbatools/issues and tell us about this failure. All information will be appreciated, but especially valuable are: - Exports of the exception: $Error | Export-Clixml error.xml -Depth 4 - Screenshots - Environment information (Operating System, Hardware Stats, .NET Version, PowerShell Version and whatever else you may consider of potential impact.) Again, I apologize for the inconvenience and hope we will be able to speedily resolve the issue.
