[severity:I'm unable to use this version] [regression] [worked-in:17.14.7]
Not sure if this is a VS or .NET issue. Building a .NET 8 solution now appears to use the .NET 10 preview 7 SDK. Building the solution shows this in the build output:

The referenced file C:\Program Files\dotnet\sdk\10.0.100-preview.7.25380.108\Roslyn\binfx\Microsoft.CodeAnalysis.dll is indeed missing.

Building the solution in VS 2022 succeeds.

@dotnet/area-infrastructure-libraries a new issue has been filed in the ApiCompat area, please triage

It looks like our targets which determine the location of Microsoft.CodeAnalysis are not finding it correctly.

sdk/src/Tasks/Microsoft.NET.Build.Tasks/targets/Microsoft.NET.ApiCompat.Common.targets

Lines 24 to 32 in d691a1a

	<!-- CSharpCoreTargetsPath and VisualBasicCoreTargetsPath point to the same location, Microsoft.CodeAnalysis.CSharp and Microsoft.CodeAnalysis.VisualBasic
	are on the same directory as Microsoft.CodeAnalysis. So there is no need to distinguish between csproj or vbproj. -->
	<RoslynAssembliesPath Condition="'$(_UseRoslynToolsetPackage)' == 'true'">$([System.IO.Path]::GetDirectoryName('$(CSharpCoreTargetsPath)'))</RoslynAssembliesPath>
	<!-- Otherwise, default to the roslyn compiler provided by the SDK / Visual Studio. -->
	<RoslynAssembliesPath Condition="'$(_UseRoslynToolsetPackage)' != 'true'">$(RoslynTargetsPath)</RoslynAssembliesPath>
	<!-- The SDK stores the roslyn assemblies in the 'bincore' subdirectory. -->
	<RoslynAssembliesPath Condition="'$(MSBuildRuntimeType)' == 'Core'">$([System.IO.Path]::Combine('$(RoslynAssembliesPath)', 'bincore'))</RoslynAssembliesPath>

Seems this might have regressed with e5f35a2. @jaredpar @jjonescz

Could be we need to come up with a different agreement for how to locate the Microsoft.CodeAnalysis.dll that matches the compiler being used by the project. We do this because we a) don't want to carry a copy and b) want to support all the same language features that the project that's being built has.
