跨多个项目的 NuGet 包

Question

I have a project which I used to create the handling of a SqLite3 database. This project gets consumed by multiple other projects which in turn gets consumed by the UI project. I only added the Nuget package to the project handling the SqLite3 interfacing.

When I attempt to run the UI, it makes calls to get information from the database, and when this happens I get a System.DllNotFoundException for SQLite.Interop.dll.

So how do I force this to work without having to add the Nuget package to all the projects in the solution?

Answer 1

Maybe your issue is similar to this one which often occurs when using Sqlite in WPF projects.

It seems that SQLite uses the entry assembly to detect which version of Interop to load.

And for your situation, the easy ways you can try to resolve it ( Make the backup first ):

1. Right-click your UI project=>Properties=>Build=>disable the Prefer 32-bit or change the platform target from Any CPU to X64 or X86 .

2. You don't have to add the nuget to all your projects in the solution, adding it to the UI project(The main project which is set as StartUp project in your solution) is enough I think.

3. Also, you can try Wil's answer ,what you need to do is: create x64 and x86 folders in your UI Project Directory(where the xx.csproj exists)=>find and copy the SQLite.Interop.dll for x64 and x86 to corresponding folders. Then in VS, right-click UI project=> unload UI project and edit xx.csproj =>copy the working-version script into the xx.csproj file, and reload the UI project.(copy the ItemGroup script within <Project> tag )

Remember to rebuild the project before you run the app.
