Application Error net::ERR_CONNECTION_REFUSED in Visual Studio Emulator

Hi All,

While i ran into an issue while running my Cordova App in the Visual Studio Emulator. After logging in to my office 365 tenant, I was getting the following error:

Application Error net::ERR_CONNECTION_REFUSED in Visual Studio Emulator

Given i have all app configuration have been set properly in Azure AD and my settings file in my cordova app (app is o365 connected).

The solution is to use Ripple emulator since it is a browser based emulator  that runs under port 4400. So once you switch your emulator to Ripple, you will be able to login to office 365 and redirect back to the redirect url.

Hope this helps.

No authUri provided nor found in O365Auth.authUri

Hi All,

While building an Apache Cordova app to integrate with Office 365  API. I connected my cordova app with office 365 by using Add -> Connected Service option in Visual Studio 2015. When i run my Cordova app try to login to office 365. I am getting the following error:

 No authUri provided nor found in O365Auth.authUri

I am using Microsoft.Office365.ClientLib.JS which allow developers to integrate with office 365 services.

The error because the Setting variable is not defined in O365Auth object. So add the follow code in o365auth.js file:

var O365Auth;
(function (O365Auth) {
    var Token = (function () ....)();
    O365Auth.Token = Token;

  //  define settings
    var Settings = {
        clientId: '6de88843-3a72-484c-af8d-3f26d2c3dd52',
        authUri: '',
        redirectUri: 'http://localhost:4400/services/office365/redirectTarget.html',
        domain: '',
        tenantId: '3323232-13e6-232323-a52a-323234423232'

    O365Auth.Settings = Settings;

Run your project and the rest of your code will pull o365 settings :-)

Hope this helps.

Can't see Office/SharePoint project templates in Visual Studio 2015 Update 1

Hi All,

I am writing this blog post to show how to get Office Developer Tools in Visual Studio 2015 Update 1. I used to have office dev tools and i was able to create Office Add-Ins earlier, but after i installed Update 1 for VS 2015. I am not able to see Office/SharePoint project templates.

When i searched for Office Developer tools, I got this link which is the main link for office dev tools:

After i installed these tools, and then restarted i was not able to see the project templates for office.

I kept searching until i found the solution and the needed components to install on your machine properly.

If you have VS 2015 Update 1, somehow these tools have been removed while installing latest bits of VS 2015 updates.

If you are using Windows 10, From the Cortana search type: Microsoft Web Platform Installer.

Install: Microsoft Office Developer Tools Update 1 for Visual Studio.

Or click on this link:

Open VS 2015 and you should be able to view Office/SharePoint project templates.
