New in ASP.NET Core 3.0 - Generic Hosting Environment

In ASP.NET Core 3.0 the hosting environment changes to get more generic. Hosting is not longer bound to Kestrel and not longer bound to ASP.NET Core. This means you are able to create a host, that doesn't start the Kestrel web server and doesn't need to use the ASP.NET Core Framework. This is a small introduction...

MySQL-Queries mitloggen

Beim Microsoft SQL Server kann man SQL Queries recht einfach mitloggen in dem man mal schnell den SQL Server Profiler startet. MySQL bietet ein derartiges Tool nicht an, zumindest kann es die MySQL Workbench nicht. Dennoch kann man aber die abgesetzten Queries aufzeichnen. So kann man beispielsweise alle Queries in...

New in ASP.NET Core 3.0: Worker Services

I mentioned in on of the first posts of this series, that we are now able to create ASP.NET Core applications without a web server and without all the HTTP stuff that is needed to provide content via HTTP or HTTPS. At the first glance it sounds wired. Why should I create a ASP.NET application that doesn't provide any...

New in ASP.NET Core 3.0 - Blazor Client Side

In the last post we had a quick look into Blazor Server Side, which doesn't really differ on the hosting level. This is a regular ASP.NET Core application that will run on a web server. Blazor Client Site on the other hand differs for sure, because it doesn't need a web server, it completely runs in the browser...

Neu in ASP.NET Core 3.0 - Blazor Server Side

To have a look into the generic hosting models, we should also have a look into the different application models we have in ASP.NET Core. In this and the next post I'm going to write about Blazor, which is a new member of the ASP.NET Core family. To be more precisely, Blazor are two members of the ASP.NET Core family...
