如何仅对选定类型的数据库使用FluentMigrator.Runner

Question

Currently when I add FluentMigrator.Runner nuget package into c# project it automatically installs all other related nuget packages: FluentMigrator.Runner.Db2 , FluentMigrator.Runner.Firebird , etc.

But I only need SqlServer support. I can't uninstall all this secondary packages because FluentMigrator.Runner depends on them.

If I force remove references I just got runtime errors:

Could not load file or assembly 'FluentMigrator.Runner.Db2, Version=3.0.0.0, 
Culture=neutral, PublicKeyToken=aacfc7de5acabf05' or one of its dependencies. 
The system cannot find the file specified.

This makes my c# project to reference a lot of useless dlls. Especially Sql Server Ce native files. Is there a way to get rid of Db2, Firebird and other implementations if I only need SqlServer?

I use Fluent Migrator version 3 and .Net 4.7.1

Here is a workaround to this problem:

1. Remove project references to the other database runners;
2. Remove entries for the other database runners in the "packages.config" file;
3. Delete all files for the other database runners in the "packages" folder for the solution;
4. Remove these lines from the .csproj file with Notepad:

 <Import Project="..\\packages\\FluentMigrator.Runner.SqlServerCe.3.1.3\\build\\netstandard2.0\\FluentMigrator.Runner.SqlServerCe.targets" Condition="Exists('..\\packages\\FluentMigrator.Runner.SqlServerCe.3.1.3\\build\\netstandard2.0\\FluentMigrator.Runner.SqlServerCe.targets')" /> <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild"> <PropertyGroup> <ErrorText>This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText> </PropertyGroup> <Error Condition="!Exists('..\\packages\\FluentMigrator.Runner.SqlServerCe.3.1.3\\build\\netstandard2.0\\FluentMigrator.Runner.SqlServerCe.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\\packages\\FluentMigrator.Runner.SqlServerCe.3.1.3\\build\\netstandard2.0\\FluentMigrator.Runner.SqlServerCe.targets'))" /> </Target>
