Implement a secure MCP OAuth desktop client using OAuth and Entra ID
The article demonstrates how to implement a secure MCP OAuth desktop client using Microsoft Entra ID. The MCP server is built with ASP.NET Core and secured using Microsoft Entra ID. The MCP client is a .NET console application that must acquire an OAuth access token to interact with the MCP server. Code: https://github.com/damienbod/McpSecurity Setup A […]
Implement a secure MCP server using OAuth and Entra ID
The article shows how to implement a secure model context protocol (MCP) server using OAuth and Entra ID. The MCP server is implemented using ASP.NET Core and uses Microsoft Entra ID to secure the API.

Reset Cookies and force new sign-in using ASP.NET Core Identity
This post looks at implementing a cookie reset in an ASP.NET Core application using Duende identity server which federates to Entra ID. Sometimes cookies need to be reset for end users due to size problems, or unknown remote authentication server errors. The cookies can be cleared and a new sign in can be forced. Code: […]
Issue and verify credentials using the Swiss Digital identity public beta, ASP.NET Core and .NET Aspire
This post shows how to issue and verify identities (verifiable credentials) using the Swiss Digital identity and trust infrastructure, (swiyu), ASP.NET Core and .NET Aspire. The swiyu infrastructure is implemented using the provided generic containers which implement the OpenID for Verifiable Credential Issuance and the OpenID for Verifiable Presentations standards as well as many other […]
