I have created a UWP application to try and connect to a SQL Server database hosted on another computer. I'm trying to connect to this server using the code below. However I'm getting what I'm understanding to be a "time out" error when trying to open the connection to the server. I can connect to the server perfectly using an identical connection string on a seperate WPF app.

Some other details about my app: Minimum and maximum version is set to "Windows 10 Fall Creators Update" App is minimum with only a button and label. More details can be provided if needed.

Edit: My question is "Any ideas for why this works fine in WPF but not in UWP using the 'Windows 10 Fall Creators Update' which apparently fully supports SQL server connectivity?"

My UWP app:

using System;
    using System.Collections.Generic;
    using System.IO;
    using System.Linq;
    using System.Runtime.InteropServices.WindowsRuntime;
    using Windows.Foundation;
    using Windows.Foundation.Collections;
    using Windows.UI.Xaml;
    using Windows.UI.Xaml.Controls;
    using Windows.UI.Xaml.Controls.Primitives;
    using Windows.UI.Xaml.Data;
    using Windows.UI.Xaml.Input;
    using Windows.UI.Xaml.Media;
    using Windows.UI.Xaml.Navigation;

    using System.Data.SqlClient;

    namespace App2
        public sealed partial class MainPage : Page
            public MainPage()

            private void Button_Click(object sender, RoutedEventArgs e)
                    string connetionString = null;
                    SqlConnection cnn;

                    connetionString = @"Data Source=DIMENSIONVRSERV\DIMENSIONVRDB;Database=mydatabase;Persist Security Info=True;User ID=DVRLaptop;Password=password";

                    cnn = new SqlConnection(connetionString);

                    Lbl_ConState.Text = "Connection Open ! ";

  • Possibly not. I'm not entirely sure what I'd need to add to the manifest to connect properly and how to add it if so.
