QueryState/QueryStateAsync generic fluent builder for JSON query generation about dotnet-sdk

[WhitWaldo]

I've open sourced this project as Innovian.Contrib.Dapr.StateQueryBuilder and published it to NuGet under the same name. I'd be happy to build it into the Dapr .NET SDK via a PR if there's any maintainer interest, especially if the query functionality graduates from its current alpha state down the road.

A fluent API for using the query state sounds great, as I've never fully grok'd how to build complex compliant query JSON myself. However, the query API in the Dapr runtime remains in the "alpha" state, with limited support from individual state stores, and there doesn't appear to be a significant push to move it forward. Given that, it might not make sense to add new query-related APIs to the existing SDK given the risk of the query API not ever becoming "stable".

That said, a separate NuGet package outside the Dapr SDK seems like a reasonable way to enable others to benefit from your hard work.

(Disclaimer: just my own opinion, not being a maintainer or approver for the SDK.)

@philliphoff I appreciate the thoughts - that's more than fair. If there's interest, I can always lift and shift into the .NET project somewhere. I'll write a follow-up note here once I've published the NuGet package.
