Files and version numbers

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics

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.

Remarks

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 don't affect any others.

For this reason, don't install the NuGet version of SMO assemblies to the Global Assembly Cache (GAC). Doing so could cause other applications, including SQL Server Management Studio, to break.
