Unit Tests Of Methods Using EF.Functions Broken By EFCore 5

[matttamatic]

In dotnet/efcore#20294 the client side implementations of EF.Functions methods (eg EF.Functions.Like) were removed which broke any unit tests using them with mockqueryable data.

I'm looking into trying to fix this by borrowing the client side implementations they deleted, but it might be beyond me

Not worth the effort, better off using inmemoryprovider for any tests that require EF extensions.

I think this is a mess, but if anybody wants it, this branch demonstrates a working unit test using EF.Like

All the extra code is taken from various classes in EFCore 5

@matttamatic I have the same problem, why have You closed the issue?

[matttamatic]

Because it was vastly easier to rewrite my broken tests using an InMemoryDatabase and every time upstream EF Core made any changes to the InMemory versions of EF.Functions, it would have to be manually pulled again.
(Basically, just that it was an unmaintainable mess)
