Recently, when deploying a project, we have hit an interesting issue – when we deployed an ASP.NET Core 2.1 application with HTTPS redirection middleware with HSTS middleware disabled, however the redirection wasn’t working correctly.Continue reading “UseHttpsRedirection on Azure App Service”
Recently, we had a project which required us to connect to a MySQL server from .NET Core with a client certificate authentication. While this seemed fairly trivial, we have hit some issues after deploying the application to Azure App Service.
When authenticating a user, you might want to persist the state through the authentication request – for example whether the user is authenticating for some special action like organizational signup or simply some state of your application. ASP.NET Core makes this very easy.
We have been migrating couple of projects to ASP.NET Core 2.0 recently. Amongst the major changes in ASP.NET Core 2.0, probably the biggest change has been done in the Authentication. I have written an article about cookie size in ASP.NET Core which explains the basic issue with too many claims in the identity. ASP.NET Core 2.0 OIDC addresses this by removing some of the token values from the identity on the background.
Sometimes, when browsing Microsoft’s sites, you can run into some weird errors – like Bad Request – Request too long or sometimes even Connection refused. These errors are mostly caused by cookies. In this article, I am going to show you the most common causes and also tips on how to avoid these issues on your sites.
Based on my previous post about B2B guest access to application, I made another sample called MyGroups. I think it demonstrates practical usage of both B2B guest access, Office 365 Groups and Microsoft Graph.
MyGroups can be used to display all Office 365 Groups to which the user has been added and additionally list direct links to the group’s SharePoint site, which is something we have been in need of internally within our company.
In the HomeController, you can find the call which is being made to Microsoft Graph’s groups endpoint to get the group’s site information – it is being made in parallel to make the request shorter for the user – generally, on average, it took about 1 second to get the site details of each group.
If you would like to use the code, just go ahead and grab the source from GitHub!
Since Microsoft’s Azure AD got the Business-to-Business (B2B) functionality, it has enabled a broad variety of new scenarios to be developed. It for example makes sharing various resources and information within applications much more easier. Today we are going to investigate the way to build an application which is not only a multi-tenant one, but also supports the user to be member of multiple directories.
When you attempt to deploy an ASP.NET Core project to App Service on Linux, you may run into an error during the build process – Object reference not set to an instance of an object. When you try to deploy the project to App Service on Windows, everything works, so where is the issue?
