Ask questions[.Net Framework 4.8]Library e_sqlite3 not found

A .Net Framework 4.8 program referencing a .Net Standard 2.0 using EFCore.Sqlite 3.1 can't simply run (on Any CPU/X64/X86) with an exception shown:

System.TypeInitializationException: The type initializer for 'Microsoft.Data.Sqlite.SqliteConnection' threw an exception. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Exception: Library e_sqlite3 not found

But the output folder does contain e_sqlite3.dll, which seems to be a bug.

To Reproduce

				var connection = "DataSource=default.db";
				var builder = new DbContextOptionsBuilder<Db>();
				var options = builder.Options;
				using (var db = new Db(options))
					db.Database.Migrate(); //this line throws that exception

I understand.

The recent changes in 2.0.5 prerelease builds are related to




When I made the code changes related to those issues, I worried that there would be cases that I broke. Your situation appears to be one such case.

I'll try to find a fix that addresses the concerns without causing breakage.
