[Feature request] Using enum comparisons in queries

[hansmbakker]

Is your feature request related to a problem? Please describe.
The archived azure-mobile-apps sdk did not support enums in queries (especially client-side).

Describe the solution you'd like
Support for queries that use enums in Where filters

var query = dataSyncClient.GetTable<InspectionSyncModel>()
    .Where(x => x.Status == InspectionStatusSyncModel.Unassigned);

var count = await query.LongCountAsync();

In the old SDK, that syntax was supported but it returned zero results for us.

Describe alternatives you've considered
Doing a string-based comparison in the Where query - this was the workaround for the old sdk.

var query = dataSyncClient.GetTable<InspectionSyncModel>()
    .Where(x => x.Status.ToString().Equals(InspectionStatusSyncModel.Unassigned.ToString(), StringComparison.OrdinalIgnoreCase));

var count = await query.LongCountAsync();

Additional context
Maybe using EF Core client-side will support this out-of-the-box?

Huh - I thought I had tests for that. In any case, I have a slew of enums in the test data, so it won't be hard to add tests for this in the future. I'll take a look. May have to wait for 8.0.1 though (even though I am adding it to the 8.0.0 milestone for now).

See the integration tests added. There are several online and pull/push offline tests using enums now.
