In this post we will look at how to read a document stored in Azure Storage, specifically in an Azure File Share, using .NET Core 2.2 and Shared Access Signature (SAS). This article assumes you have an Azure Account and an Azure Storage Account. Create an Azure File Share in your Azure Storage Account, which…
In a previous article, Adventures with Azure AD: Group Overage Claim, I talked about how to handle, in an ASP.NET MVC Core application, the group overage claim that is sometimes returned in the claims for an authenticated user. I had a customer contact me saying that the code I provided them was not working as…
Came across this article from Chris Pietschmann, an oldie but goodie. Check it out at https://buildazure.com/designing-globally-resilient-apps-with-azure-app-service-and-cosmos-db/.

The first example uses a custom IAuthorizationFilter to look at the groups in principal claims. The second example uses a custom…
In a previous article, Adventures with Logic Apps: Enabling/Disabling a Logic App from Another Logic App, I created a Logic App that would disable a Logic App and then re-enable it after a specific time frame had elapsed. One of my peers pointed out that the Logic App should NOT disable the Logic App if…
Recently I was asked to create an HTTP Endpoint that could a user could call to disable a Logic App. At first I thought about doing this as an Azure Function, but thought first I’d try it using a Logic App. Albert Hovingh’s article, Disabling Logic Apps from Other Logic Apps, pointed me in the…
