How to log NHibernate SQL to ASP.NET Core loggers

Logging down SQL created by 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 log SQL created by NHibernate to ASP. NET Core logger using NHibernate interceptor. NB! In this post I will extend some parts of code shown in my blog post NHibernate on ASP. NET Core. 07:01 20.08.2020 kanalilt DT blogi 2


Using Structuremap in legacy ASP. NET MVC applications.

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. Legacy warning! The code here and solutions are for classic ASP. NET MVC. 09:23 18.08.2020 kanalilt DT blogi 2


Building ASP. NET Core applications on Visual Studio Codespaces and Visual Studio Code.

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. 10:20 07.08.2020 kanalilt DT blogi 2


Surface Go 2 review

Recently I bought Surface Go 2 tablet with Intel M3 CPU and LTE. Surface Go 2 is hybrid device being either tablet or small laptop. It is lightweight and therefore not the option for resource demanding workloads. Consider it more as an complementary device that is hyper-portable and supports you well if you are moving around. But Surface Go 2 is not yet another tablet – it’s more. 23:30 03.08.2020 kanalilt DT blogi 2


IIS Express error: Failed to register URL for site.

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. It wasn’t any of the classic problems. Classic ones have one of these solutions: Open solution in Windows Explorer, close Visual Studio and delete . vs folder. 08:50 01.08.2020 kanalilt DT blogi 2

Hosting WordPress behind Azure Front Door

During lockdown I tried out how Azure Front Door works. It is another member of Azure load balancers and traffic routers world but it is global and designed for web applications. My only interest was to see how it works and if it is just for commercial sites or does it also fit for private WordPress blogs like I have. It was interesting journey full of of surprises and here’s the overview of what I did and how things worked out. 07:34 19.05.2020 kanalilt DT blogi 2


Using Dapper in ASP.NET Core applications

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. 11:39 14.05.2020 kanalilt DT blogi 2


Optimize database traffic with future results in NHibernate

One nice feature that NHibernate has is future results. It is technically a capability to put queries on hold until data is actually asked. When data is asked from one delayed query then all queries are sent to database server as one batch and results are read also as one batch of multiple result sets. This blog post explains how to use future results with NHibernate. 09:13 25.03.2020 kanalilt DT blogi 2


Displaying enum as select list in ASP.NET Core

Some properties of model classes come as enums and we want to show enum values in select list when edit form is opened. Sometimes we want enum element names but sometimes we want to use custom names or even translations. his blog post demonstrates how to get enum element names to select list on ASP. NET Core. Let’s suppose we have customer entity that has customer type property defined as enum. 13:41 24.03.2020 kanalilt DT blogi 2


EF Core 5. 0: Using ToQueryString() method to translate LINQ query to SQL.

Entity Framework Core 5. 0 comes with SQL-based brother to ToString() method for LINQ-queries. This method is called ToQueryString() and it returns provider-specific SQL without connecting to database server. In some means it’s similar to ToTraceString() method of Entity Framework. This blog post shows how ToQueryString() method works. NB! At the time of writing this post . NET Core 5. 0 and EF Core 5. 08:15 20.03.2020 kanalilt DT blogi 2


Using query strings in ASP.NET Core unit tests

Using query string in controller unit tests is actually easy until we don’t need anything more advanced. We can buld up a string with query parameters and go with it. But what if things get more complex and we need encoding or multiple values? Here’s how to build safe query string for ASP. NET COre controller unit tests. NB! It is recommended to use action method arguments instead of request query parameters in your controllers. 07:37 18.03.2020 kanalilt DT blogi 2


Updating SQL Azure database using Visual Studio database project and Azure DevOps

Visual Studio database projects have been one of my important tools since Visual Studio 2010. Database projects were not easy to use with build servers ten years ago. Today things are different. It’s super easy to use database projects to update staging and live databases from Azure build and release pipelines. This blog post shows how to do it. 09:00 10.03.2020 kanalilt DT blogi 2


Creating storage accounts and blob containers using Azure fluent API-s

Using Azure fluent API-s it is easy to create storage accounts and blob containers. After experimenting with fluent API of Azure storage I found it to be good match for multitenant web applications where tenant files are held on Azure blob storage. I was surprised how clean and short code I got using fluent API. Here’s my overview of fluent API for Azure storage with some code samples I wrote. 08:28 04.03.2020 kanalilt DT blogi 2


MSSQL data and log files on Azure blob storage

I discovered lately one killer feature of SQL Server – keeping data and log files on Azure blob storage. There are scenarios where we may want to go with blob storage instead of buying and building up our own stable and reliable storage.

Implementing repository querying interface in EF Core DbContext

My last bold statement was that we don’t need custom unit of work and repository classes with Entity Framework Core. One issue remained unsolved and it was querying part of repositories (yeah, those custom querying methods). After some experiments to get querying interface of repositories to DbContext I worked out something that I kind of like. I managed to make DbContext to work like classic unit of work that hosts repository instances. 08:00 03.02.2020 kanalilt DT blogi 2
