I'm trying to implement Redis caching in our sitecore setup, but I'm having trouble doing so. We are running dotnet framwork 4.8 in a containerized setup. I've install StackExchange.Redis Nuget package version 2.7.27, and I'm trying to write to the cahce using db.StringSet(applicationCacheKeyEnum.ToString(), objectJsonString, TimeSpan.MaxValue, true, When.Always);. My code compiles, but at runtime I get the following error:

{
"Message": "An error has occurred.",
"ExceptionMessage": "Method not found: 'Boolean StackExchange.Redis.IDatabase.StringSet(StackExchange.Redis.RedisKey, StackExchange.Redis.RedisValue, System.Nullable`1<System.TimeSpan>, Boolean, StackExchange.Redis.When, StackExchange.Redis.CommandFlags)'.",
"ExceptionType": "System.MissingMethodException",
"StackTrace": "......"}

As far as I can see the signature of my method call matches Redis' StringSet() method, so I don't understand why this is happening. Below is the method in which I'm trying to set the cache value:

    public void AddToCache(ApplicationCacheKeyEnum applicationCacheKeyEnum, object theObject)
{
    IDatabase db = _redisAccessor.Redis.GetDatabase(0);
    string objectJsonString = JsonConvert.SerializeObject(theObject, Formatting.Indented);
    db.StringSet(applicationCacheKeyEnum.ToString(), objectJsonString, TimeSpan.MaxValue, true, When.Always);
}

    <PackageReference Include="StackExchange.Redis" />
  </ItemGroup>

Can anyone help me understand, what causes the error?

    "I've install StackExchange.Redis Nuget package version x.x.x.x" - I'd be surprised if "x.x.x.x" is actually the version you're using, and seeing as this is very likely to be a versioning problem, the actual version is really important. Commented Mar 11, 2024 at 10:10

    Additionally, if you could provide a minimal reproducible example so that others could reproduce the problem, that would make a huge difference. Commented Mar 11, 2024 at 10:10
  • @JonSkeet You're right, of course, about the version number. I menat to get the exact version number before posting, but forgot, sorry - i've edited the question Commented Mar 11, 2024 at 11:52
  • Okay, that's a start. Now for more information - are you able to run the code when it's not containerized? What projects are involved? Basically the more information you can provide - again, ideally a minimal reproducible example - the more likely it is that we can help you. Commented Mar 11, 2024 at 11:57
  • As @JonSkeet said - try providing a minimal reproducible example or at least share contents of relevant .csproj files. Commented Mar 11, 2024 at 12:37
