System.MissingFieldException: 'Field not found: 'ControlzEx.Behaviors.WindowChromeBehavior.TryToBeFlickerFreeProperty'.' about controlzex

[batzen]

@niprst You are totally right about the breaking changes section in the release notes. Just added it there.

[batzen]

That's because it was removed in v6.
You have to re-compile your code when updating major versions of ControlzEx.
Simply replacing the dll does not work for major versions.

@batzen I'm also facing the same issue as mentioned by @Anakazel
Exception thrown: 'System.MissingFieldException' in Microsoft.Xaml.Behaviors.dll
An exception of type 'System.MissingFieldException' occurred in Microsoft.Xaml.Behaviors.dll but was not handled in user code
Field not found: 'ControlzEx.Behaviors.WindowChromeBehavior.TryToBeFlickerFreeProperty'.

re-compile the code as well but no success.

Could you search your code for usages of the property?
If there is code using it, it shouldn't compile.
If there is no code using it, it would be nice if you could attach a repro.

[kamalkaushik1]

I have searched for this property in the code base but not found any reference.
Sorry I can't share the repro it is private

[batzen]

Are you using any other library that references ControlzEx?

[Khaos66]

I had this issue as well. I'm using MahApps.Metro which states

[batzen]

Using ControlzEx 6.0 with MahApps.Metro 2.X is not possible.

The removal of this property is not mentioned in the v6.0.0 release notes breaking changes.
You are right upgrade to a new major version can bring breaking changes, but we should be able to evaluate them from the release note and not trying and hope nothing is hidden.
