Files and Version Numbers
All required SQL Server Management Object (SMO) components are included in the Microsoft.SqlServer.SqlManagementObjects NuGet package. SMO is implemented in several managed assemblies. You can develop SMO applications on either a client or a server.
The file version of the SMO assemblies is displayed as Major.0.Build.Revision. But the embedded assembly version is Major.100.Build.Revision. This is done to keep the version of SMO used in each application separate so updates to one doesn't affect any others.
Because of this you should not install these versions of the assemblies to the Global Assembly Cache (GAC). Doing so could cause other applications, such as SQL Server Management Studio, to break.
