Hi, i tried to make a blazor webassembly projekt and currently i cant use System.Data.SQlite because the SQLite.Interop.dll apparently can not be found.

System.DllNotFoundException: SQLite.Interop.dll assembly:<unknown assembly> type:<unknown type> member:(null) at (wrapper managed-to-native) System.Data.SQLite.UnsafeNativeMethods.sqlite3_config_none(System.Data.SQLite.SQLiteConfigOpsEnum) at System.Data.SQLite.SQLite3.StaticIsInitialized () <0x2f0a020 + 0x00034> in <filename unknown>:0 at System.Data.SQLite.SQLiteLog.PrivateInitialize (System.String className) <0x2f096d8 + 0x00044> in <filename unknown>:0 at System.Data.SQLite.SQLiteLog.Initialize (System.String className) <0x2f029d0 + 0x0003a> in <filename unknown>:0 at System.Data.SQLite.SQLiteConnection..ctor (System.String connectionString, System.Boolean parseViaFramework) <0x2eac638 + 0x00032> in <filename unknown>:0 at System.Data.SQLite.SQLiteConnection..ctor (System.String connectionString) <0x2e8b488 + 0x00008> in <filename unknown>:0 at Echo.Pages.Counter.IncrementCount () [0x00001] in C:UsersRobertsourcereposEchoEchoPagesCounter.razor:18 at Microsoft.AspNetCore.Components.EventCallbackWorkItem.InvokeAsyncT <0x2e63698 + 0x0006e> in <filename unknown>:0 at Microsoft.AspNetCore.Components.EventCallbackWorkItem.InvokeAsync (System.Object arg) <0x2e635d8 + 0x0000a> in <filename unknown>:0 at Microsoft.AspNetCore.Components.ComponentBase.Microsoft.AspNetCore.Components.IHandleEvent.HandleEventAsync (Microsoft.AspNetCore.Components.EventCallbackWorkItem callback, System.Object arg) <0x2e63538 + 0x0000a> in <filename unknown>:0 at Microsoft.AspNetCore.Components.EventCallback.InvokeAsync (System.Object arg) <0x2e630c0 + 0x00040> in <filename unknown>:0 at Microsoft.AspNetCore.Components.RenderTree.Renderer.DispatchEventAsync (System.UInt64 eventHandlerId, Microsoft.AspNetCore.Components.RenderTree.EventFieldInfo fieldInfo, System.EventArgs eventArgs) <0x2e605f8 + 0x000a8> in <filename unknown>:0

I am currently using Visual Studio Community 2019 16.10.3 and .NET SDK 5.0.301.

I saw there is a workaround for the problem, but not for .Net Standard 2.1

The SQLite.Interop.dll is currently located under


but not in the project folder. Maybe i can copy the dll manually?

Maybe someone has an idea to make the package work again.

Maybe this is related to the recent MSBuild issue?

This was my thought also. But i can't use the workaround because a .net standard project doesn't have this folder/file.

I tried to copy the .dll files by hand to

C:\Users\$User\source\repos\Echo\DataLibrary\bin\Debug\netstandard2.1\x86 C:\Users\$User\source\repos\Echo\DataLibrary\bin\Debug\netstandard2.1\x64

but with no luck and at the moment i am pretty clueless what to do next.

When i run

dotnet build --version

i get

Microsoft (R)-Build-Engine, Version 16.10.1+2fd48ab73 für .NET Copyright (C) Microsoft Corporation. Alle Rechte vorbehalten.

although i am using VS 16.10.3. I dunno how the change this. Everything should be up to date.

I think i have to wait for an update vor MSBuild 16.10.2?

This version of MSBuild shipped with Visual Studio 2019 version 16.10.2 and will ship with .NET SDK 5.0.302.
