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

问题描述

使用 XUnit 和 Asp.Net Core 5 我有以下测试：

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，但并非总是如此：

ServiceProviderFixture课程是：

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班级是：

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);

    }

  }

我错过了什么吗？

也许从文件中读取？
