Does Apache Ignite 3 successfully working with .NET 8?

[Maximys]

I tried to figure out how to use Apache Ignite with a .NET application. I changed solution for this by next commit. But for some reason, when I try to get data from Apache Ignite , I get the following error:

Apache.Ignite.IgniteClientConnectionException
  HResult=0x80131500

  This exception was originally thrown at this call stack:
    [External Code]

Inner Exception 1:
IgniteClientConnectionException: Invalid magic bytes returned from the server: FF-FF-57-86-00-00-00-00-00-00-00-00-00-00-00-00

In the logs of the ignite_instance container, I see the following messages:

2025-03-21 15:36:45 WARNING: package jdk.internal.access not in java.base
2025-03-21 15:36:45 WARNING: An illegal reflective access operation has occurred

Could you please tell me what I'm doing wrong?

Looks like the server is Ignite 2.x, while the client is Ignite 3. Those are not compatible.

There is no problem with .NET 8.

@ptupitsyn , thanks. After this changes I see some messages after each request to Ignite in Ingine container logs:

but as you can see, it's still unsuccessfully.
May be there is some instruction for integrating Apache Ignite to .NET application?

[ptupitsyn]

You should connect the client to port 10800. 3344 is for node-to-node comms.

Here is a detailed getting started guide for .NET developers:

Hope this helps!

Thanks, @ptupitsyn . I had not call
Invoke-RestMethod -Uri "http://localhost:10300/management/v1/cluster/init" -Method Post -Headers @{"Content-Type"="application/json"} -Body '{"metaStorageNodes": ["defaultNode"], "clusterName": "myCluster"}'
for initialize Ignite cluster, that's why I had error.
