Blazor 发布版本 Mono.Cecil.AssemblyResolutionException

Question

我正在尝试获取 Blazor WebAssembly 项目的发布版本，但我总是遇到 Mono.Cecil.AssemblyResolutionException 异常。它不适用于示例 Microsoft 项目：

> dotnet new blazorwasm -o WebApplication1 --hosted

The template "Blazor WebAssembly App" was created successfully.

我已经搜索过这个错误，它恰好是一个流行的错误，Whosebug - asp.net github - mono github 之间有很多交叉链接。适用于我的情况的唯一解决方案是通过在项目文件中添加 <BlazorWebAssemblyEnableLinking>false</BlazorWebAssemblyEnableLinking> 来禁用链接器。但这没有帮助，它给了我以下错误：

如何让它在 Release 配置中可以编译？

Answer 1

感谢 Mister Magoo 的提示。

看起来 SDK 5.0 预览版在某种程度上干扰了它。我尝试添加具有以下内容的 global.json 文件：

{
    "sdk": {
      "version": "3.1.402"
    }
}

但这并没有帮助。然后我卸载了.NET Core SDK 5.0.0-preview，现在它可以编译了。
