【问题描述】:
我有一个 ASP.Net Core 应用程序,当我尝试启动它时,以下行会抛出 System.TypeLoadException:
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);
if (env.IsEnvironment("Development"))
{
// This will push telemetry data through Application Insights pipeline faster, allowing you to view results immediately.
builder.AddApplicationInsightsSettings(developerMode: true);
}
builder.AddEnvironmentVariables();
Configuration = builder.Build(); // <-- exception is thrown here
}
异常内容如下:
Could not load type 'System.Runtime.Serialization.ISerializable' from assembly 'System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'.
这就是我的 project.json 的样子:

引用的项目都是netstandard1.5
我尝试将"System.Runtime.Serialization.Primitives": "4.3.0" 添加到我的依赖项中,但没有成功。
有人知道我必须做什么才能成功启动我的项目吗?
【问题讨论】:
-
解决方案的目标框架是什么? 4.0 或更高版本。如果更高,请尝试设置为 4.0。
-
目标是netcoreapp1.0;因为我使用的是 ASP Core,所以无法将其设置为 4.0、4.5 等。
-
您是否尝试过将其作为依赖程序集添加到配置中。
-
这是 .Net Core,没有 .csproj 来添加依赖组件。但是如上所述,我尝试将其添加到 project.json 中但没有成功。
-
对不起,我不熟悉 .Net Core。也没有“Web.config”吗?这就是配置设置的地方
