运行MSBuild时发生内部故障-无法加载文件或程序集System.Net.Primitives

Question

使用XUnit和Asp.Net Core 5，我进行了以下测试：

public class Tests : IClassFixture<ServiceProviderFixture> {
private readonly ServiceProviderFixture _fixture;
public IndicatorsTests(ServiceProviderFixture fixture) {
_fixture = fixture;
}
[Fact]
public async Task FirstTest() {
IEnumerable<Decimal> values = await _fixture.Provider.GetService<ICsvImporter>().ImportAsync("Values.csv");
Assert.Equal(1000, values.Count());
}
}

当我运行测试时，我经常会收到错误，但并不总是：

MSBUILD : error MSB1025: An internal failure occurred while running MSBuild.

ServiceProviderFixture类为：

public class ServiceProviderFixture : IDisposable {
public IServiceProvider Provider { get; private set; }
public ServiceProviderFixture() {
IServiceCollection services = new ServiceCollection();
services.AddSingleton<CsvImporterConfiguration>();
services.AddTransient<ICsvImporter, CsvImporter>();
Provider = services.BuildServiceProvider();
}
public void Dispose() { } // Dispose
}

CsvImporter类为：

public class CsvImporter : ICsvImporter {
private readonly CsvImporterConfiguration _configuration;
public CsvImporter(CsvImporterConfiguration configuration) {
_configuration = configuration;
}
public CsvImporter(Action<CsvImporterConfiguration> configuration) {
_configuration = new CsvImporterConfiguration();
configuration(_configuration);
} 
public async Task<IEnumerable<Decimal>> ImportAsync(String path, CancellationToken token = default(CancellationToken)) {
return await Task.Factory.StartNew(() => {
using (StreamReader stream = new StreamReader(path)) {
using (CsvReader csv = new CsvReader(stream, new CsvConfiguration(_configuration.Culture) { 
Delimiter = _configuration.Delimiter
})) {
return csv.GetRecords<Decimal>();
}
}
}, token);
}
}

我是不是错过了什么？

也许是从文件中读取？

这是MacOS上的一个已知问题。

这种情况似乎最常见于安装防病毒软件时。

我见过好几个这样的案例。唯一的"；"修复"；我发现是卸载了杀毒软件。在某些情况下，我们不得不重新安装MacOS。

如果您没有使用MacOS，请告诉我们。
