Stumbled across my MS thesis about the importance of processes in Software Development
Just stumbled across my 2004 MS thesis – “A Case Study into the Effects of Software – Process Improvement on Product Quality” – as study into the effects of agile project process maturity on the types of defects that surface in a software product. Still interesting stuff (at least some of the principles discovered) almost
Blazor: Modifying header meta and link elements
When creating web applications, we all try to create good SEO tags in the header of each page. Modifying the meta tags based on page content is a standard practice. In Blazor, this is not obvious as the _host.cshtml is rendered before the Blazor execution pipeline. There was a tag extension in the preview of
Fixing google authentication due to my half-ass https setup
The problem Google Authentication on my Blazor app worked locally but not live – hosted @DigitalOcean in Ubuntu Docker Containers. Locally I was working https using devcerts and the https on the DigitalOcean droplet was faked using Cloudflare’s (super-nice) security features (where they basically hide your website behind ssl without any certificate installation. I switched
Mac: Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date.
For 3 hours I was dealing with the title error nothing seems to work until I read the answer from hikrikunen where the key was deleting the localhost certificates in the system keychain and then running dotnet dev-certs https –clean and then dotnet dev-certs https -t Uptil the point of deleting the localhost certificates, the
Blazor: having a App/Pages/System folder will kill your app!?
Fun discovery of the day … when building Blazor – having a Pages subfolder called System will completely mess upp the application build. Renaming the folder to SystemX (or anything else for that matter) will make those errors disappears 🙂 This is possibly a result of some local coincidence … but I can reproduce this
Migrating from mssql to postgres in ef6
I was faced with the project of migrating an mssql database to postgres (why? mainly because of licensing fees as we are about to go live with the solution – without any revenues any time soon 🙂 ) This is more a #notetoself if im faced with this again rather than any kind of guideline

EF6 core – load grandchildren in query – the key is ThenLoad
Working with entity: Tournament Which has children: TRound with Course as entity that needs to be loaded based on Id ( as each golf round is played on a Course 🙂 ) ctx.Tournaments.Include(c => c.Trounds).ThenInclude(c => c.Course) Took me a while to figure out why ctx.Tournaments.Include(c => c.Trounds.Select(c => c.Course)) stopped working, but it is
Blazor OnClick doesn’t fire
#notetoself … Once again, scratching my head for way to long about something that turns out to have a simple workaround #devlife On one of my (new) blazor pages (/Bookings/TeeTimes), onclick event was not firing. Didn’t matter what kind of flavour of onclick declaration I used, the event was not getting fired. Until of course
NullPointer exception in SyncFusion Listview (SfListView) #notetoself
If the ListViewFieldSettings element is missing when building Blazor… (build validation or code complete doesn’t catch this mistake) This results in a nullpointer exception which is difficult to debug #notetoself #devlife

SqlException: Invalid column name GolferId
EF6 Core – reconfiguring navigation properties, the runtime was complaining about a column GolferId being missing (invalid database column). Took me a minute to figure out and remember the default foreign key dependency naming convention in EF. Sometimes these frameworks are a bit too intelligent for my taste. Turns out the EF was guessing that
