I am exploring Azure redis cache to use one of our application. I create a .net Core (3.1) Console application as given in the article https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-dotnet-core-quickstart

while i running the app am getting the below error

StackExchange.Redis.RedisConnectionException

    Hi @anurag Sharma

    When i update StackExchange.Redis to 2.1.58, i am getting the below error:

    Restoring packages for E:\RnT\Test\Redistest\Redistest.csproj...
    NU1605: Detected package downgrade: System.Buffers from 4.5.1 to 4.5.0. Reference the package directly from the project to select a different version.
    Redistest -> StackExchange.Redis 2.1.58 -> Pipelines.Sockets.Unofficial 2.1.16 -> System.Buffers (>= 4.5.1)
    Redistest -> System.Buffers (>= 4.5.0)
    NU1605: Detected package downgrade: System.Runtime.CompilerServices.Unsafe from 4.7.1 to 4.5.2. Reference the package directly from the project to select a different version.
    Redistest -> StackExchange.Redis 2.1.58 -> Pipelines.Sockets.Unofficial 2.1.16 -> System.Runtime.CompilerServices.Unsafe (>= 4.7.1)
    Redistest -> System.Runtime.CompilerServices.Unsafe (>= 4.5.2)
    Package restore failed. Rolling back package changes for 'Redistest'.

    System.Buffer and System.Runtime.CompilerServices.UnSafe is really required ?

    Please advise.
