Port completion, quick info, parameter info, go-to-definition, and diagnostics coverage from the Windows-only VS Salsa suite to the cross-platform FSharp.Compiler.Service.Tests. The legacy suite keeps only the tests that genuinely exercise Visual Studio integration. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
…Info helper - ScriptDiagnostics closure: use assumeDotNetFramework=false/useSdkRefs=true on coreclr so the script closure resolves FSharp.Core where no .NET Framework exists (Linux/Mac/Win-transparent). - ScriptOptions SurfaceOrderOfHashes: guard #if !NETCOREAPP; it asserts desktop-GAC assemblies (System.Runtime.Remoting/System.Transactions) that cannot resolve on a Core-only host. - Legacy ParameterInfo: delete the now-callerless TestSystematicParameterInfo helper; its wrapper tests were migrated to FCS and a leftover [<Fact>] on the parameterized member failed discovery (0ms).

…the transparent compiler The migrated legacy test only checked that the resolvable reference produced no squiggle; the whole-closure assertClosureNoDiagnostics over-translated it. The transparent compiler surfaces the deliberately-missing reference as a warning (the classic one does not), so filter that expected warning before asserting none remain.

Reference/#load script checks funnelled through a shared "Test.fsx" identity, so the .NET Framework FCS checker's filename-keyed script-closure cache leaked one test's resolved/failed references and their diagnostics into another under concurrency (empty #r tooltips; phantom "'' is not a valid assembly name" squiggles). Route those checks through a unique script identity via getParseAndCheckResultsUniqueName. Plain-code tests keep the fast shared path. Remove 13 tests whose asserted behaviour is already covered: duplicates within the migrated set (tooltip PriorityQueue/exception/module-alias, gotodef record fields, paraminfo single-arg/generic-location, an if-clause completion that also lives in the completion suite) and two diagnostics covered by executed ComponentTests (FS0010 negative enum literal, FS0433 entrypoint-not-last).

The Visual Studio Salsa unit tests exercised compiler-service logic — completion, quick info, parameter info, go-to-definition, and diagnostics — but only ran on Windows through a mock VS harness. This ports that coverage to the cross-platform FSharp.Compiler.Service.Tests, so it runs on every target the compiler does and no longer depends on Visual Studio.
The ports are behaviour-preserving: each assertion moves onto the equivalent FCS API. The legacy suite keeps only the tests that genuinely exercise Visual Studio integration (project-system, editor events, solution lifecycle).
