"You need to call SQLitePCL.raw.SetProvider()" error when using Microsoft.EntityFrameworkCore.Sqlite 5.0.4 via C++\CLI wrapper

Start by reproducing the difference between DAL.Test and DAL.Interop.Test from the linked EFCore5SQLiteCLRTest repository. Inspect DAL/CRUD.cs at line 14, then compare the project references and runtime setup for the managed and C++/CLI test applications. Done means DAL.Interop.Test can create the database without the SQLitePCL provider exception while DAL.Test continues to pass.

I have a solution with the following structure:

• DomainObjects - .NET 5.0 class library without any special dependencies, contains entities. Compiled as x86.
• DAL (references DomainObjects) - .NET 5.0 class library which references Microsoft.EntityFrameworkCore.Sqlite 5.0.4 nuget package, contains DbContext and migrations (database is created at d:\test.db). Compiled as x86.
• DAL.Test (references DAL) - .NET 5.0 console test application. Compiled as x86.
• DAL.Interop (references DAL) - .NET 5.0 C++\CLI wrapper. Compiled as x86, Multi-byte Character Set, wchar_t-.
• DAL.Interop.Test - C++ console test application. Compiled as x86, Multi-byte Character Set, wchar_t-.

DAL.Test runs without any problems, but DAL.Interop.Test throws an exception (inside DAL class library):

You need to call SQLitePCL.raw.SetProvider(). If you are using a bundle package, this is done by calling SQLitePCL.Batteries.Init().

NB! If I switch from Microsoft.EntityFrameworkCore.Sqlite provider to Devart.Data.SQlite.EFCore provider - both test applications (.NET and C++) run without any problems.

NB2! If I remember correctly code was working with no problems with Microsoft.EntityFrameworkCore.Sqlite 3.1 on .NET Core 3.1.

Sample repo - https://github.com/bairog/EFCore5SQLiteCLRTest
Compile it (for some reason you need to compile twice for compiling DAL.Interop.Test project) and start debugging DAL project (it starts DAL.Interop.Test.exe in project Debug settings)
