WPF .Net 4.5 App - MahApps looking for System.Windows.Interactivity 4.0

[GeorgeB2009]

I have a .WPF Net 4.5 application that as soon as I add MahApps stops working as it's looking for System.Windows.Interactivity 4.0

I've not seen any issues with using the .NET 4 version of MahApps.Metro in a .NET 4.5.

Here's a simple sample to test out: link

Can you elaborate on what issues you're seeing?

EDIT: to clarify, System.Windows.Interactivity is a binary from Microsoft - I don't believe they ship a .NET4.5-specific version.

As soon as I add <Controls:MetroWindow do I see the exception

The inner exception

{"Could not load file or assembly 'System.Windows.Interactivity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)":"System.Windows.Interactivity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"}

and here is the reference I have in my project

c:\Program Files (x86)\Microsoft SDKs\Expression\Blend.NETFramework\v4.5\Libraries\System.Windows.Interactivity.dll

What do you have installed on your machine in terms of Expression Blend?

I can investigate what's changed between these versions and confirm we can pull this in for a .NET 4.5 project without issues.

Blend + SketchFlow Preview for VS 2012 - came with VS 2012

[GeorgeB2009]

So I took your sample and it runs no problem.

Then I thought I would add in the NuGet packages I'm using.

Cocktail 2012 - which includes DevForce 2012 and Caliburn Micro
MefContrib
EntityFramework 5

It still works fine.

I'll did around some more but what is interesting is it only crashes when I add in MahApps. I take it out and the app works. Doesn't look good but it works.

Ok, so some context:

We're using System.Windows.Interactivity for it's Behaviour/EventTriggerIinteraction/TriggerAction etc components. But it's expecting the .NET 4 version - which we include in the NuGet package.

Because you already have it referenced (Caliburn.Micro I gather) installing MahApps.Metro doesn't install the .NET 4 version.

Shouldn't be too hard to fix, but what I need to do is:

• confirm the .NET 4.5 version of System.Windows.Interactivity works fine with MahApps.Metro
• update our pre-release package to include the .NET 4.5 version of System.Windows.Interactivity
• might have to ship a .NET 4.5 version of the MahApps.Metro assembly

[GeorgeB2009]

Awesome.

And keep up the great work. I know of a large listed company that is using MahApps for their internal systems and the users are loving it.

Drop me a line (email is in my GitHub profile) - would love to hear more about it.

Wish I had more time to spend on this, so any feedback around what works and what they'd like to see would be excellent.

[GeorgeB2009]

Will do. They've just gone live so the guys are heads down. I know they spent quite a bit of time on styling as their corporate colours are green and they needed to make the Infragistics components work with the same colours.

They use it as a front-end to JD Edwards (their ERP system).

I've just pushed 0.10.1.33-ALPHA which includes the .NET45 version (and is signed). Can you confirm the fix works with your scenario?

Install-Package MahApps.Metro -Pre

[GeorgeB2009]

Perfect. Works a treat.

Thanks for the help.

You're welcome
