复制SQLite.Interop.dll到项目目录。

src\
  project\
      bin\   <-- Past in bin
         x64\
           SQLite.Interop.dll <-- Copy this if 64
         x86\
           SQLite.Interop.dll <-- Copy this if 32

升级到Visual Studio 2019版。16.10导致了我的问题，其中msbuild报告了以下System.Data.SQLite.Core-package:

CopySQLiteInteropFiles:
Skipping target "CopySQLiteInteropFiles" because it has no outputs.

https://github.com/dotnet/msbuild/issues/6493

微软表示，该漏洞已被修复。16.10.4. 现在只需要等待AppVeyor更新他们的Visual Studio图像(在此之前，可以使用以前的Visual Studio 2019)。

现在，AppVeyor正在为当前和以前的Visual Studio 2019-image使用破碎的dotnet-build-engine。现在一个必须显式安装dotnet sdk ver。5.0.302:

Invoke-WebRequest -Uri 'https://dot.net/v1/dotnet-install.ps1' -UseBasicParsing -OutFile "$env:temp/dotnet-install.ps1"; & $env:temp\dotnet-install.ps1 -Architecture x64 -Version 5.0.302 -InstallDir "$env:ProgramFiles\dotnet"

这是我在我的项目中解决它的方法。

它正在工作，当一位同事提交他的更改时，我收到了“无法加载DLL 'SQLite.Interop.dll'”异常。

区别项目的.csproj文件，这是在NON-WORKING版本中:

<ItemGroup>
     <Content Include="x64\SQLite.Interop.dll" />
     <Content Include="x86\SQLite.Interop.dll" />
</ItemGroup>

下面是WORKING版本的内容:

<ItemGroup>
     <Content Include="x64\SQLite.Interop.dll">
          <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      </Content>
      <Content Include="x86\SQLite.Interop.dll">
          <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      </Content>
</ItemGroup>

在返回之后，我没有收到异常。DLL文件被转储到适当的Debug\x64 (etc)文件夹中。

Mine didn't work for unit tests either, and for some reason Michael Bromley's answer involving DeploymentItem attribute didn't work. However, I got it working using test settings. In VS2013, add a new item to your solution and search for "settings" and select the "Test Settings" template file. Name it "SqliteUnitTests" or something and open it. Select "Deployment" off to the right, and add Directory/File. Add paths/directories to your SQLite.Interop.dll file. For me, I added two paths, one each for Project\bin\Debug\x64 and Console\bin\Debug\x86. You may also want to add your Sqlite file, depending on how you expect your unit test/solution to access the file.

旧项目文件格式

即以<Project ToolsVersion="3.5" DefaultTargets="Build"开头的项目xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

将以下内容添加到“主”/根项目的csproj中

<PropertyGroup> 
    <ContentSQLiteInteropFiles>true</ContentSQLiteInteropFiles>
    <CopySQLiteInteropFiles>false</CopySQLiteInteropFiles>
    <CleanSQLiteInteropFiles>false</CleanSQLiteInteropFiles>
    <CollectSQLiteInteropFiles>false</CollectSQLiteInteropFiles>
</PropertyGroup>

新的SDK项目文件格式

例如，以<Project Sdk="Microsoft.NET.Sdk.*"开头的项目>

将PrivateAssets="none"添加到System.Data.Sqlite PackageImport依赖链中的每个ProjectReference/PackageImport

ex:

<PackageReference Include="System.Data.SQLite.Core" Version="1.0.110" PrivateAssets="none"/>

将x86和x64的“SQLite.Interop.dll”文件复制到调试文件夹中。这些文件应该复制到调试文件夹中的“x86”和“x64”文件夹中。
