[BUG] Type cannot be inferred from GetOrSetAsync

[celluj34]

Describe the bug Since updating to 0.21, types cannot be inferred from GetOrSetAsync.

To Reproduce

var date = _cache.GetOrSetAsync("my date",
    async (context, token) =>
    {
        return DateTime.Now;
    });

Expected behavior I expect the types to be inferred from the return type of the factory.

Versions I've encountered this issue on:

• FusionCache version 0.21

Screenshots

Additional context You can work around the issue by providing the type explicitly in the method call, like so:

var date = _cache.GetOrSetAsync<DateTime>("my date",
    async (context, token) =>
    {
        return DateTime.Now;
    });

Hi @celluj34 , yep it was in the release notes

Sadly there's nothing I can do, it seems to be a limitation of the current version of the compiler.

Ah, I see. Sorry I did not read thoroughly enough, I was too excited to start using the conditional refresh feature! Thank you for setting me straight!

I'm you were expecting it so much, if you like let me know how it went 😁

Honestly it's so much nicer than what I had to do before. The previous flow was complicated and we had to store 3 values for each set of data. We wanted to keep our data for 1 hour, but check at a maximum of every 10 minutes for staleness.

The way you've built the new methods with the existing FailSafe logic is just perfect for our use case.

Hi @celluj34 , what can I say? Thanks for your words, they made my day 😊

I'm glad it ended up working well and that you are liking the way I designed it, it means a lot!
