我正在使用这些软件包开展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
更新为3.1.1
,将Caliburn.Micro
从1.5.1
更新为1.5.2
(使用Nuget Package Manager
})。在那之后,我无法运行该项目。我收到这个错误:
'在类型'MyAppBootstrapper'上调用构造函数 匹配指定的绑定约束引发异常。线 数字'9'和行位置'22'。
在App.xaml
的这一行:
内部异常消息是:
{“未找到方法:'无效 Caliburn.Micro.Bootstrapper`1..ctor(布尔型)”。“}
我错过了升级是否有任何意义?

答案 0 :(得分:9)
好吧,我找到了答案:)问题在于:
Caliburn.Micro.Autofac nuget包中的Caliburn.Micro.Autofac.AutofacBootstrapper<TRootViewModel>
( version =“1.5.0”)在中扩展Caliburn.Micro.Bootstrapper<TRootModel>
Caliburn.Micro 包,并有一个像这样的构造函数:
public AutofacBootstrapper() : base(true) { }
这意味着它通过传递base.ctor
参数(boolean
)来调用base.ctor(bool)
。事情就是这样。版本Caliburn.Micro.Bootstrapper<TRootModel>
中的1.5.1
包含一个bool
参数的构造函数:
public Bootstrapper(bool useApplication = true) : base(useApplication) {
this.Start();
}
在版本1.5.2
中,它只有一个无参数构造函数:
public Bootstrapper() : base(true) {
this.Start();
}
以下是签名:
// 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();
}
}
}
因此,Caliburn.Micro.Autofac, Version=1.5.0.0
无法与Caliburn.Micro, Version=1.5.2.0
一起使用,您必须创建自己的AutofacBootstrapper
,这很容易通过引用原始{{1}}来实现或阅读nuget包源。此外,here是我重新实施的,如果您需要的话。
