Orleans error: Orleans.Storage.BadProviderConfigException: No storage providers found loading grain type

Next step in my journey into Orleans land, was using ‘Declarative Persistence’. Sometimes you want the state inside your actors(grains in Orleans terminology) being persisted in some kind of permanent storage, so that it can survive a silo shutdown. Orleans provides a simple declarative model that makes this possible.

Unfortunately while following the related tutorial, I got the following error message:

What I was missing were the following lines inside my orleansconfiguration.xml:

<OrleansConfiguration xmlns="urn:orleans">
  <Globals>
    <SeedNode Address="localhost" Port="11111" />
    <StorageProviders>
      <Provider Name="AzureStore" Type="Orleans.Storage.AzureTableStorage" DataConnectionString="UseDevelopmentStorage=true"/>
    </StorageProviders>
  </Globals>
  <Defaults>
    <Networking Address="localhost" Port="11111" />
    <ProxyingGateway Address="localhost" Port="30000" />
  </Defaults>
</OrleansConfiguration>

On my grains I had the following attribute added:

[StorageProvider(ProviderName = "AzureStore")]
public class Employee : Grain<EmployeeState>, IEmployee
{

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…
