UWP App SQLite Access database in Documents Library

App: Universal Windows (10) Platform
Development: C#, Visual Studio 2015
SQLite: Using SQLite.net
Targets: Windows 10 Desktop and Windows 10 Phone

Deployment: From Visual Studio or Sideloaded (Do not need Store deployment)

using SQLite;
using SQLite;   
using SQLite.Net;   
using SQLite.Net.Async;   
using SQLite.Net.Attributes

I can:

• Open and read from a database included in the project as content:

  var path = Path.Combine (Windows.Storage.ApplicationData.Current.LocalFolder.Path, "mydb.db3");

  using (SQLite.Net.SQLiteConnection conn = new SQLite.Net.SQLiteConnection (new SQLite.Net.Platform.WinRT.SQLitePlatformWinRT(), path)) { //Read queries }

• Open/Create and Read/Write a database to the apps workspace:

  string path = Path.Combine (Windows.Storage.ApplicationData.Current.LocalFolder.Path,"another.db3"); using (SQLite.Net.SQLiteConnection conn = new SQLite.Net.SQLiteConnection (new SQLite.Net.Platform.WinRT.SQLitePlatformWinRT(), path)) { //CRUD }

• Copy another.db3 to Documents

• From there copy to an External Memory Device (SD Card)

I can't

• Open the database in Documents or SD

• I use a FilePicker to choose the db in Documents or the SD

• I then use the File.Path property when attempting to open the database connection

  Windows.Storage.StorageFile File = await FilePicker.PickSingleFileAsync();
  string path = File.Path;

I get the following error message:

Exception thrown: 'SQLite.Net.SQLiteException' in SQLite.Net.dll
SQLite-GetAllVendors: Could not open database file: C:\Users\me\Documents\another.db3 (CannotOpen)

Have added SQLite .db and .db3 file associations.

      <Extensions>
        <uap:Extension Category="windows.fileTypeAssociation">
          <uap:FileTypeAssociation Name=".db">
            <uap:DisplayName>SqliteDB</uap:DisplayName>
            <uap:EditFlags OpenIsSafe="true" />
            <uap:SupportedFileTypes>
              <uap:FileType>.db</uap:FileType>
              <uap:FileType>.db3</uap:FileType>
              <uap:FileType>.jpg</uap:FileType>
            </uap:SupportedFileTypes>
          </uap:FileTypeAssociation>
        </uap:Extension>
      </Extensions>
    </Application>
  </Applications>

Have added the relevant Capabilities

  <Capabilities>
    <Capability Name="internetClient" />
    <uap:Capability Name="picturesLibrary" />
    <uap:Capability Name="documentsLibrary" />
    <uap:Capability Name="videosLibrary" />
    <uap:Capability Name="userAccountInformation" />
    <uap:Capability Name="removableStorage" />
    <DeviceCapability Name="webcam" />
    <DeviceCapability Name="microphone" />
    <DeviceCapability Name="location" />
  </Capabilities>

Surely there is some way to open a SQLite database in Documents or on a memory stick form a Universal Windows (10) app.
Thx in advance
