[jira] [Updated] (IGNITE-18059) .NET: Thin 3.0: Error codes should be constants

["Pavel Tupitsyn (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-18059?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Pavel Tupitsyn updated IGNITE-18059:
------------------------------------
    Description: 
Currently, error codes in generated *ErrorGroups* class are *static readonly int*, because we calculate them at runtime with *GetFullCode*.

However, this prevents pattern matching. The following does not work:
{code}
if (e is IgniteClientConnectionException { Code: ErrorGroups.Client.ClusterIdMismatch })
{
    ...
}
{code}

Compiler error: *[CS0150] A constant value is expected*.

Since we use code generation, it is easy to compute error codes at compile time and use constants to make things nicer for the users.
