ASP.NET

One of the new features in .NET 6 is support for global using declarations. We can define using declarations as global and they work all over the project so we don’t have to define them in other files anymore. Here’s how it works.

During moving one system from classic ASP.NET MVC to ASP.NET Core I faced an interesting challenge. Although access to system is based on Active Directory there is separate role management based on classic membership and roles providers. There are reasons why AD is not used for role management and I cannot change it. ASP.NET Core uses claims-based authentication and I needed to find a way to add role claims to authenticated identity. Here’s the solution.

Although .NET 5 is officially in RC and not yet officially supported on Azure cloud we can still deploy ASP.NET Core web applications built for .NET 5 to Azure App Services. I made my first ASP.NET Core 5.0 deployment to Azure App Service last week. There has been no problems on Azure side and my application is running very stable. Here’s how I did it.

When working with stateless sessions in NHibernate we need some way to see generated SQL but we cannot use simple tricks as custom NHibernate interceptor to log SQL queries. As I’m using mostly NHibernate LINQ these days I was interested in how to get SQL out from LINQ query without actually executing it. Here’s my solution.

Logging SQL created by NHibernate ORM is useful when debugging new features of application. SQL logging in NHibernate is a little bit tricky and not so straightforward as it is with Entity Framework Core. This blog post demonstrates how to write SQL created by NHibernate to ASP.NET Core loggers using NHibernate interceptor.

Dependency Injection (DI) was also supported by classic ASP.NET MVC but there was no framework-level dependency injection like in ASP.NET Core. In this blog post I will show how to use Structuremap for dependency injection in ASP.NET MVC applications and how to resolve dependencies using built-in components in classes that doesn’t support dependency injection.

On the search for running development environments on cloud I stumbled upon service calles Visual Studio Codespaces. It’s nice service that moves development and debugging workloads to cloud and it makes it possible to use lightweight machines like tablets and hybrids for development. Here’s my overview of how to build ASP.NET Core web applications on codespaces and Visual Studio Code.

A little surprise during COVID-19 time coding. I cloned repo to my dev box, opened it in Visual Studio and hit F5. IIS Express starts and browser opens but it shows just error about site to be unreachable. After almost getting grey hair I found out what’s wrong. Here’s the solution.

Something funny to end this week. When checking my Twitter feeds I found a kinky tweet about logging .NET Core messages to Notepad window. Yes, you heard right – .NET Core logger for Notepad. It’s not real, you want to say, but it is. And here’s how it works :)

Times ago I blogged about micro ORM-s. I have been busy through all Covid-19 times learning technical side of DDD and during that I met again my old friend Dapper. There are applications where Dapper is used to query read-only data without overhead coming with ORM-s. Also there are simple applications where for one or another reason developers decided to keep as close to raw SQL as possible. This blog post is brief introduction to Dapper anbd how to use it in ASP.NET Core applications.
