Hey, if you use net48 and sqlite1.0.113 or higher you don't get interop libs anymore. this example still works without problems: <Project Sdk="Microsoft.NET.Sdk.WindowsDesktop"> <PropertyGroup> <OutputType>WinExe</OutputType> <TargetFramework>net48</TargetFramework> <UseWPF>true</UseWPF> <PlatformTarget>AnyCPU</PlatformTarget> </PropertyGroup> <ItemGroup> <PackageReference Include="System.Data.SQLite.Core" Version="1.0.112" /> </ItemGroup> <PropertyGroup> <ContentSQLiteInteropFiles>true</ContentSQLiteInteropFiles> <CopySQLiteInteropFiles>false</CopySQLiteInteropFiles> <CleanSQLiteInteropFiles>false</CleanSQLiteInteropFiles> <CollectSQLiteInteropFiles>false</CollectSQLiteInteropFiles> </PropertyGroup> </Project> but once you increase and rebuild the version of sqlite.core, the interop libs are no longer loaded into the output directory. how to solve this problem? best regards, Henry.
