そこで、クライアント DACのみで PowerShell を使用することにしました (これは実際にはスクリプトに近いため) 。ここの例はとても役に立ちました。
MSBuild 拡張パックを使用すると、PowerShell ボイラープレートをラップするタスクを作成できます。
DAC 3.0 にアクセスするには、PowerShell 3 をインストールする必要があることに注意してください。これは、Windows Management Framework 3.0 をインストールすることによって最適に実現されます。
次のような TaskFactory ラッパー:
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

which are compatible with SQL Server 2012 and later, and SQL Azure -->

これらのラッパーを呼び出すサンプル ターゲットは、次のようになります。
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Import Project="BacpacImportExport.xml"/>
<PropertyGroup>
<TempBacpacFile>$(ReleaseFolderPublish)\$(DestinationDBName).bacpac</TempBacpacFile>
</PropertyGroup>
<Target Name="CopyAndReplaceDatabaseViaBacpac">
<Message Text="Clean bacpac directory"/>
<Exec Command="mkdir $(ReleaseFolderPublish)\" IgnoreExitCode="true"></Exec>
<Exec Command="del /Q $(ReleaseFolderPublish)\*.bacpac " IgnoreExitCode="true"></Exec>
<MSBuild Projects="$(MSBuildProjectFile)" Targets="ReportBuildProgress" Properties="Message=Exporting database to BACPAC from source"/>
<ExportBacpac
ConnectionString="$(SourceConnectionString)"
BacpacFile="$(TempBacpacFile)"
DatabaseName="$(SourceDBName)"
/>
<MSBuild Projects="$(MSBuildProjectFile)" Targets="ReportBuildProgress" Properties="Message=Dropping database from destination (does not fail on error)"/>
<MSBuild.ExtensionPack.SqlServer.SqlCmd TaskAction="Execute" Server="$(DestinationDBServer)" Database="master"
LogOn="$(DestinationDBUser)" Password="$(DestinationDBPass)"
CommandLineQuery="DROP DATABASE [$(DestinationDBName)];"
RedirectStandardError="true" SeverityLevel="1" />
<MSBuild Projects="$(MSBuildProjectFile)" Targets="ReportBuildProgress" Properties="Message=Importing database from BACPAC to destination"/>
<ImportBacpac
ConnectionString="$(DestinationConnectionString)"
BacpacFile="$(TempBacpacFile)"
DatabaseName="$(DestinationDBName)"
/>
</Target>
</Project>
これは、参照実装のコンソール アプリを呼び出す代わりに、ホストされた DACを使用するように簡単に修正できます。<Exec Command="" />
<ImportBacpac />
改善点があれば教えてください!
