[SOLVED] Microsoft.Data.SQLite: Library e_sqlite3 not found


I’m trying to develop an ASP.NET MVC (.Net Framework 4.7.2) web app in which I want to use Microsoft.Data.Sqlite version (5.0.2), but when I run it my web app crashes (both in debug IIS Express, and in app.publish on local IIS on Windows 10) at following code line:

SqliteConnection dbConn = new SqliteConnection("Data Source=test.db");

The exception thrown is as under:

  Message=The type initializer for 'Microsoft.Data.Sqlite.SqliteConnection' threw an exception.
   at Microsoft.Data.Sqlite.SqliteConnection..ctor(String connectionString)
   at sqliteTest.Controllers.ValuesController.Get() in C:\Users\FaqeerHussain\source\repos\sqliteTest\sqliteTest\Controllers\ValuesController.cs:line 16
   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass6_2.<GetExecutor>b__2(Object instance, Object[] methodParameters)
   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)
   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ExecuteAsync(HttpControllerContext controllerContext, IDictionary`2 arguments, CancellationToken cancellationToken)

  This exception was originally thrown at this call stack:
    [External Code]

Inner Exception 1:
TargetInvocationException: Exception has been thrown by the target of an invocation.

Inner Exception 2:
Exception: Library e_sqlite3 not found

What I’ve tried so far:
Following Inner Exception: Library e_sqlite3 not found tried looking around the ‘bin’ folder, and found that e_sqlite3.dll is already there in bin\runtimes\win-x64\native and also in bin\runtimes\win-x86\native folders, both contain e_sqlite3.dll.
Tried copying manually the above-mentioned x86/x64 e_sqlite3.dll to root bin folder but the error still remains.

What should I do to get Microsoft.Data.Sqlite working in my ASP.NET MVC (.NET Framework 4.7.2) web app?


This is because the package of Microsoft.Data.Sqlite is not compatible with the version of .Net Framework. You can try to change the version of NuGet of Microsoft.Data.Sqlite to 2.2.0 to run normally.
