If you work with .NET Core the Json format is absolutely the best way because .NET Core offers a package that makes easy to bind the json file into a C# class but let's proceed in order, the json first:
{
"Redis": {
"Password": "my_super_secret_password",
"AllowAdmin": true,
"Ssl": false,
"ConnectTimeout": 6000,
"ConnectRetry": 2,
"Database": 0,
"ServiceName" : "my-sentinel", // In case you are using Sentinel
"Hosts": [
{
"Host": "192.168.0.10",
"Port": "6379"
},
{
"Host": "192.168.0.11",
"Port": "6381"
}]
},
"MaxValueLength" = 1024,
"PoolSize" = 5,
"KeyPrefix" = "_my_key_prefix_",
}
