[snickler]

Summary of the Pull Request

What is this about:
This PR removes the tlbimp-Microsoft.Search.Interop NuGet package and replaces with COM Interop interfaces/classes to provide an implementation that works with what is currently used .

What is included in the PR:

• tblimp-Microsoft.Search.Interop NuGet package removed
• SearchAPI implementation of SearchManager, SearchQueryHelper, and SearchCatalogManager
• Microsoft.Search.Interop.dll removed from Setup

How does someone test / validate:

Thanks a lot for opening this PR @snickler
This will really help in supporting arm64

Where do the class definitions come from, though? Any Microsoft docs or were they reverse engineered? Could you please link the source here or explain how you generated those?
Thanks, in advance.

It was generated using tlbimp.exe on SearchAPI.tlb per:

• https://docs.microsoft.com/en-us/dotnet/framework/interop/how-to-generate-interop-assemblies-from-type-libraries.
• https://github.com/microsoft/Windows-classic-samples/blob/67a8cddc25880ebc64018e833f0bf51589fd4521/Samples/Win7Samples/winui/WindowsSearch/DSearch/DSearch.csproj#L99

The tlb-Microsoft.Search.Interop NuGet package is the result of the command.

After generating the library, I initially used ILSpy and integrated the generated C# into the Indexer project, but I kept running into Access Violations when properties on the queryHelper were set. I went through tons of trial and error, used JetBrains dotPeek to generate the source properly.

I then realized what was wrong the entire time, it was because the definition for SearchAPI listed the put_xxxx methods before the set_xxxxx ones. ILSpy generates the C# source with { get; set } in that static order, whereas many properties needed to be { set; get }. It took me a while to realize it after using dotPeek.

When I verified it worked, I removed the bulk of the generated source files and kept only the minimal implementation of search based on ISearchManager, ISearchQueryHelper, ISearchCatalogManager use.
