System.Data.SQLite

I recently in a .NET WPF project using SQLite and spatialite found a problem, when I use the SQLite load extension many times, again using the OpenFileDialog, the program will crash. The cause of the crash is an exception to the COM component, the code for the 0x8007045A. I simplify the problem into the following test code:

            var b = new System.Data.SQLite.SQLiteConnectionStringBuilder();
            b.DataSource = @"C:\Users\jdire\Downloads\db.sqlite";
            for (int i = 0; i < 1500; i++)
            {
                var cnn = new System.Data.SQLite.SQLiteConnection(b.ConnectionString);
                cnn.Open();

                cnn.EnableExtensions(true);
                cnn.LoadExtension("mod_spatialite");



                cnn.Close();
                cnn.Dispose();

                cnn = null;

            }
            b = null;

            var dlg = new OpenFileDialog();
            dlg.ShowDialog(); // Crash at here



I use the .net version SQLite 1.0.102.0 , the Spatialite version is 4.3.0a. If I use 4.0.0 Spatialite, it won't be the problem. If I don't load extension, it won't be the problem. Do not know what is missing from my code, or where there is BUG, I hope you can help me.

Thank you very much.

From the sound of things, it really sounds like an issue with Spatialite.  Their
