wpf - 未找到方法 : 'Void Caliburn.Micro.Bootstrapper` 1. .ctor(Boolean)'

Question

我正在使用这些包开发一个 WPF 项目:

<package id="Autofac" version="3.0.2" targetFramework="net40" />
<package id="Caliburn.Micro" version="1.5.1" targetFramework="net40" />
<package id="Caliburn.Micro.Autofac" version="1.5.0" targetFramework="net40" />

直到昨天我将软件包更新为:

<package id="Autofac" version="3.1.1" targetFramework="net40" />
<package id="Caliburn.Micro" version="1.5.2" targetFramework="net40" />
<package id="Caliburn.Micro.Autofac" version="1.5.0" targetFramework="net40" />

我的意思是，我将 Autofac 从 3.0.2 更新到 3.1.1 并将 Caliburn.Micro 从1.5.1 到 1.5.2(通过使用 Nuget 包管理器)。之后，我无法运行该项目。我收到此错误:

'The invocation of the constructor on type 'MyAppBootstrapper' that matches the specified binding constraints threw an exception.' Line number '9' and line position '22'.

在App.xaml中的这一行:

内部异常消息是:

{"Method not found: 'Void Caliburn.Micro.Bootstrapper`1..ctor(Boolean)'."}

我错过的升级有什么意义吗？

Answer 1

好吧，我找到了答案:)问题就在这里:

Caliburn.Micro.Autofac.AutofacBootstrapper<TRootViewModel>在 Caliburn.Micro.Autofac nuget 包 (version="1.5.0") 中扩展 Caliburn.Micro.Bootstrapper<TRootModel>在Caliburn.Micro包中，并且有一个像这样的构造函数:

public AutofacBootstrapper() : base(true) { }

这意味着它调用 base.ctor通过传递 boolean参数( base.ctor(bool) )。事情就是这样。 Caliburn.Micro.Bootstrapper<TRootModel>版本1.5.1有一个带有 bool 的构造函数参数:

public Bootstrapper(bool useApplication = true) : base(useApplication) {
  this.Start();
}

版本 1.5.2 ，它只有一个无参数构造函数:

public Bootstrapper() : base(true) {
  this.Start();
}

这是签名:

// Assembly: Caliburn.Micro.Autofac, Version=1.5.0.0
namespace Caliburn.Micro.Autofac {
    public class AutofacBootstrapper<TRootViewModel> : Bootstrapper<TRootViewModel> {
        public AutofacBootstrapper() : base(true) { }
    }
}

// Assembly: Caliburn.Micro, Version=1.5.1.0
namespace Caliburn.Micro {
    public class Bootstrapper<TRootModel> : BootstrapperBase {
        public Bootstrapper(bool useApplication = true) : base(useApplication) {
            this.Start();
        }
    }
}

// Assembly: Caliburn.Micro, Version=1.5.2.0
namespace Caliburn.Micro {
    public class Bootstrapper<TRootModel> : BootstrapperBase {
        public Bootstrapper() : base(true) {
            this.Start();
        }
    }
}

所以，Caliburn.Micro.Autofac, Version=1.5.0.0不能与 Caliburn.Micro, Version=1.5.2.0 一起使用你必须创建自己的 AutofacBootstrapper ，通过引用原始包( here )或阅读 nuget 包源代码很容易实现。另外，here如果您需要的话，这是我重新实现的。
