I am playing with EventStore. As a .NET user I prefer Windows as OS, only that I have home edition. In order to install Docker I need Windows Proffessional Edition - and I don't have it ... it's out of my budget.
Anyway, I kept trying to install (via Chocolatey) and I managed it. How do I start it? I can't find the command in the documentation.
I am having this code:
var settings = new EventStoreClientSettings {
    ConnectivitySettings = {
        Address = new Uri("http://localhost:2113")
    }
};
var client = new EventStoreClient(settings);
taken from here.
I am gettig an error "Error starting gRPC call - the connection cannot be created".
I suspect that I need to start the server. But how? even if I am using docker, I would still be unable to start the server with a command line, as I my experience tells me that I would do in these kind of situations.
I would gladely contact their support, however I am just exploring - I do not have a licence for this software.
For GRPC
download the zip file from https://www.eventstore.com/downloads and unzip into a local folder
or install eventstore-oss from choco
for version 20.10 run
EventStore.ClusterNode.exe --insecure --run-projections=all --start-standard-projections  --enable-atom-pub-over-http
Open localhost:2113 in a browser and confirm the db is running
Use connection string esdb://localhost:2113?Tls=false for gRPC clients.

browse to http://localhost:2113/web/index.html#/streams to confirm the written stream(s).
Click the links for the stream details
e.g. http://localhost:2113/web/index.html#/streams/item-{item id}
and http://localhost:2113/web/index.html#/streams/item-{item id}\0 for the first event
the item category is at http://localhost:2113/web/index.html#/streams/$ce-item
the ItemCreated events at http://localhost:2113/web/index.html#/streams/$et-ItemCreated
the ItemChanged events at http://localhost:2113/web/index.html#/streams/$et-ItemChanged
Once it's been installed via chocolatey you can use the following command to start EventStoreDB
EventStore.ClusterNode.exe --db ./db --log ./logs
However, if you are wanting to access it over HTTP (as in your sample) then you will need to also need to add the --insecure flag
EventStore.ClusterNode.exe --db ./db --log ./logs --insecure
