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

Question

I was working on a WPF project using these packages:

<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" />

Until yesterday that I update packages to:

<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" />

I mean, I update Autofac from 3.0.2 to 3.1.1 and Caliburn.Micro from 1.5.1 to 1.5.2 (by using Nuget Package Manager). After that, I cannot run the project. I get this error:

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

at this line in App.xaml:

The inner exception message is:

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

Is there any point to upgrading I did that I missed?

Well, I found the answer :) The problem is here:

The Caliburn.Micro.Autofac.AutofacBootstrapper<TRootViewModel> in Caliburn.Micro.Autofac nuget package (version="1.5.0") extends Caliburn.Micro.Bootstrapper<TRootModel> in Caliburn.Micro package, and has a constructor like this:

public AutofacBootstrapper() : base(true) { }

It means it calls the base.ctor by passing a boolean argument (base.ctor(bool)). And here is the thing. The Caliburn.Micro.Bootstrapper<TRootModel> in version 1.5.1 has a constructor with a bool parameter:

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

while in version 1.5.2, it has only one parameter-less constructor:

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

Here is the signatures:

// 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();
        }
    }
}

So, the Caliburn.Micro.Autofac, Version=1.5.0.0 cannot be used with Caliburn.Micro, Version=1.5.2.0 and you have to create your own AutofacBootstrapper, which is easy to implement by referring the original one (here) or reading the nuget packages source. Also, here is my re-implemented one, if you need.

Thanks, you saved me a lot of time :) Have you tried to get in touch with Dave and fix his package on GitHub? – Deejay

U'r welcome. Yep, I left a comment on his blog (post about Caliburn.Micro.Autofac here) but he didn't answer. – Joellajoelle

I think you can just make a change and make a commit request. – Deejay
