System.ArgumentNullException ：值不能为 null。（参数“类型”）OData 单元测试升级到 .NET 6.0

Question

我最近升级到 .NET 6.0，现在在我的 OData 单元测试项目中遇到了以前未见过的错误。我遇到了：System.ArgumentNullException：值不能为空。运行以下单元测试时出现（参数“type”）错误：

\n

        [Fact]\n        public void Startup_Configure_Ok()\n        {\n            // Arrange   \n            ServiceCollection serviceCollection = new ServiceCollection();\n            serviceCollection.AddOData();\n            ServiceProvider provider = serviceCollection.BuildServiceProvider();\n            var appBuilder = new ApplicationBuilder(provider);       \n            var routeBuilder = new RouteBuilder(appBuilder);\n            routeBuilder.EnableDependencyInjection();\n\n            Startup startup = new Startup(_fixture.GetConfiguration());\n\n            // Act\n            startup.Configure(appBuilder);\n\n            // Assert\n            Assert.True(true);\n        }\n

有什么建议么？

我看到了完全相同的症状，并通过将 Microsoft.AspNetCore.OData 版本升级到 7.5.17 来修复。
