如何使 FSI 在 NET5 下工作并生成愚蠢的 stackoverflow 消息“标题不能包含..."闭嘴?

问题描述

我正在将一个相当小的 F# 项目从 Net Framework 迁移到 NET5.迁移非常简单，一切正常，包括测试.

但是，当我运行一些脚本时，我现在收到以下错误:

文件 fsi.runtimeconfig.json 包含正确的信息:

{运行时选项":{tfm":net5.0"，框架":{名称":Microsoft.NETCore.App"，版本":5.0.0"；}}}

有没有人知道如何强制 FSI 选择 NET 5 而不是 Net Framework?

解决方案

截至 Visual Studio 2019 16.9 版，您可以启用使用 dotnet fsi 运行交互式 F# 脚本的选项.这适用于 .NET 5 代码.

这是通过工具设置的 >选项 >F# 工具 >F#互动 >使用 .NET Core 脚本.

I am migrating a fairly small F# project from Net Framework to NET5. The migration was very easy and everything works including the tests.

However, when I run some scripts I am now getting the following error:

Microsoft (R) F# Interactive version 11.0.0.0 for F# 5.0

When I examine Project.fsproj.resolvedReferences.paths from C:\Users\kkkma\AppData\Local\Temp\nuget\28772--091a5e4a-2a27-4d4d-9891-2b58055c5317 (and that's the folder created by FSI when I run the script) I see that it starts from C:\Users\kkkma\.nuget\packages\microsoft.netframework.referenceassemblies.net48\1.0.0\build\.NETFramework\v4.8\Facades\System.Runtime.InteropServices.RuntimeInformation.dll and it also has some other Net Framework resolved references. Which makes me believe that FSI somehow "decides" to use Net Framework instead of NET 5.

The file fsi.runtimeconfig.json contains correct information:

{
  "runtimeOptions": {
    "tfm": "net5.0",
    "framework": {
      "name": "Microsoft.NETCore.App",
      "version": "5.0.0"
    }
  }
}

Does anyone have an idea how to force FSI pick up NET 5 instead of Net Framework?

解决方案

As of Visual Studio 2019 version 16.9, you can enable an option to use dotnet fsi to run interactive F# scripts. This works with .NET 5 code.

This is set via Tools > Options > F# Tools > F# Interactive > Use .NET Core Scripting.
