.NET Core + BenchmarkDotNet 실행 시 프레임워크를 찾지 못하는 문제
.NET Core Console 프로젝트에서 BenchmarkDotNet을 이용해 성능 테스트를 하는 경우 다음과 같은 출력 결과가 나올 수 있습니다.
// ***** BenchmarkRunner: Start *****
// Found benchmarks:
// LoopTest.ForLoopTest: DefaultJob [N=1000]

BenchmarkDotNet이 CoreCLR을 찾는 기준이 뭔지는 모르겠지만 메시지에 나온 "2.1.0-preview1-26216-03" 버전이 어떻게 나온 것인지 이해가 안 됩니다. 왜냐하면 (64비트로 실행한 위의 예제는) 그 버전과 관련된 dotnet 런타임 설치는 한 적이 없기 때문입니다. (물론, 제가 모를 수도 있지만!) 다음은 제 컴퓨터에 설치된 (x64 버전의) sdk와 runtime의 목록입니다.

어쨌든 저 목록에 없기 때문에 그런 오류가 발생한 것입니다. 관련해서 직접적인 해결 방법을 찾을 수는 없었는데요, 대신 csproj의 RuntimeFrameworkVersion을 명시하는 것으로 우회할 수 있었습니다.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp2.1</TargetFramework>
<RuntimeFrameworkVersion>2.1.0</RuntimeFrameworkVersion>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
<AllowUnsafeBlocks>true</AllowUnsafeBlocks>
<PlatformTarget>x64</PlatformTarget>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
<AllowUnsafeBlocks>true</AllowUnsafeBlocks>

<ItemGroup>

</ItemGroup>
</Project>
"dotnet --list-runtimes" 명령어로 출력된 목록 중에 원하는 버전을 RuntimeFrameworkVersion에 명시하면 .NET Core Console 응용 프로그램이 그 환경에서 동작하게 됩니다. 이럴 때 BenchmarkDotNet은 별다른 버전 찾기를 하지 않아 오류가 발생하지 않는 것 같습니다.
