Using MSAL in a VB.Net Winforms application

All of our MSAL samples are for either Web, mobile client or console applications in c#. This blog post will show how you can also use MSAL in vb.net in a Winforms desktop application. When creating a winforms application, the thing to remember is that code in your form will run under the UI thread, which, for the most part is ok. However, when MSAL prompts for credentials, it will…

What’s the security implication of changing the default client type from confidential to public in Azure AD?

From time to time, I get asked this question by a few different customers especially when they encounter the error “AADSTS7000218: The request body must contain the following parameter: ‘client_assertion’ or ‘client_secret’” when authenticating to Azure AD. The error is related to the following Default client type setting in the Authentication blade of a registered application: By default the setting is set to No (confidential client). Changing to ‘Yes’ converts…

In this post we will use PowerShell to instantiate an MSAL Public Client Application to perform an Authorization Code Grant flow to obtain a delegated permission Access Token for Microsoft Graph. We will then use that access token to call Microsoft…

Using MSAL.Net to perform the client credentials flow with a certificate instead of a client secret in a .NetCore console appliction.

The sample files for this post can be found in this GitHub repository: https://github.com/RayGHeld/NetCore_ClientCredentials_withCert There is also a Powershell script there to create a certificate for this sample.

Using PowerShell to get Azure AD audit logs

In my previous blog, I talked about how to use PowerShell with Microsoft Graph Reporting API. In that blog, I used the Client Credentials grant flow to acquire an access token for Microsoft Graph against the V1 endpoint. Also the code sample in that blog only works if all the reporting data result set is small. In this blog I’ll discuss how to get a Microsoft Graph access token using…

VB.NET – Use MSAL.Net in a Console Application to Authenticate to Azure

At one point in recent history, VB.Net was one of the most popular development languages around.

How to set your MSAL.js app up to automatically sign-in if you already have a session signed in on another tab

Our MSAL.js sample is an excellent example for using MSAL in a javascript page. However, it only demonstrates logging in by clicking on a button. If you’re launching your app from myapps portal or are otherwise already logged into the portal with the browser, it would make sense to just use that session to perform your sign-in for your MSAL app without requiring the button click. This is actually easily…
