NEventStore PollingClient does nothing

For my next project we’ll use Event Sourcing. Therefore I’m spending some free time in looking at NEventStore, a persistence agnostic Event Store for .NET.

One of the features of NEventStore is a built-in PollingClient allowing you to poll the Event Store for the latest commits. However when I tried to test the PollingClient nothing happened?!

Here is the code I was using:

No exception was thrown, however when I browsed through the Output window in Visual Studio I noticed the following message:

A first chance exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in NEventStore.dll

It seems that the PollingClient immediatelly tries to deserialize the committed events, as I didn’t include a reference to the assembly containing the Events, the deserializer (silently) fails.

To fix it, the only thing I had to do was adding a reference to my Events assembly.

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
