After upgrading to net5 I'm getting obsoletion warning:
[CS0618] 'HttpRequestMessage.Properties' is obsolete: 'Use Options instead.'
however there seems to be no migration guide.
I.e. there's following code
httpRequestMessage.Properties.Add(Key, Value);
How exactly it should be migrated? Is
httpRequestMessage.Options.Set(new HttpRequestOptionsKey<TValue>(Key), Value);
correct?
You could switch on type - here's an example from attempting to clone an existing message:
foreach (var opt in httpRequestMessage.Options)
{
switch (opt.Value)
{
case string s:
clone.Options.Set<string>(new HttpRequestOptionsKey<string>(opt.Key), s);
break;
default:
throw new InvalidOperationException("Can't deal with non-string message options ... yet.");
}
}
