The term 'Microsoft.SqlServer.Dac.BacPackage::Load' is not recognized

Question

I have created a bacpac from an azure sql db, copied it to blob, from blob brought it down locally.

I run this code in powershell

Add-Type -path "C:\Program Files (x86)\Microsoft SQL Server\140\DAC\bin\Microsoft.SqlServer.Dac.dll"
$restoredDatabaseName = 'AuditTest'
$bacpacFile = "H:\backup\audit\audit.bacpac"
$conn = "Data Source=.;Initial Catalog=master;Connection Timeout=0;Integrated Security=True;"

$importBac = New-Object Microsoft.SqlServer.Dac.DacServices $conn
$loadBac = Microsoft.SqlServer.Dac.BacPackage::Load($bacpacFile)
$importBac.ImportBacpac($loadBac, $restoredDatabaseName)

#Clean up
$loadBac.Dispose()

Get this error back:

Microsoft.SqlServer.Dac.BacPackage::Load : The term 'Microsoft.SqlServer.Dac.BacPackage::Load' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the 
name, or if a path was included, verify that the path is correct and try again.

I have also tried to use the import data tier wizard and get the following error.

Could not load file or assembly 'Microsoft.SqlServer.Dac, Version=13.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. (Microsoft.SqlServer.Management.Dac.DacWizard)

It is driving me nuts, I have found a few things about registry hacking and so on for the wizard error, nothing helpful at all for the powershell one.

Answer 1

When invoking a static method, the full type name goes in square brackets.

So should be:

Add-Type -path "C:\Program Files (x86)\Microsoft SQL Server\140\DAC\bin\Microsoft.SqlServer.Dac.dll"
$restoredDatabaseName = 'AuditTest'
$bacpacFile = "H:\backup\audit\audit.bacpac"
$conn = "Data Source=.;Initial Catalog=master;Connection Timeout=0;Integrated Security=True;"

$importBac = New-Object Microsoft.SqlServer.Dac.DacServices $conn
$loadBac = [Microsoft.SqlServer.Dac.BacPackage]::Load($bacpacFile)
$importBac.ImportBacpac($loadBac, $restoredDatabaseName)

#Clean up
$loadBac.Dispose()
