Inheritance security rule violation while initializing Xpand.ExpressApp.Chart.Win.XpandChartWinModule

[AndreasMock1]

We have migrated our XAF project from DX 20.1.4 to 20.2.5 and eXpand to the according versions, when doing so we also changed dependencies from referencing assemblies directly to Nuget packages.

When we now deploy the software to client machines, it throws an error during start up:

What is a possible cause for this error and how can we solve it?

Thanks for your support.

can u repro it in an empty XAF solution having installed and register the XpandChartWinModule?

[AndreasMock1]

Unfortunately not, application compiled from the sample project attached is starting up. Do you have any idea for what to check in the project not working?

inheritance_Security_violation_repro.zip

[apobekiaris]

the exception is about a version missmtach i would start by clearning the nuget cache and the temp dirs. If does not start by that u haave to make sure that your dependecies are correct e.g. use the container packages only and remove any binding redirections from your app.config

let me know

[apobekiaris]

also I totally suggest u use the DX nugets rather than Gac refererences

[apobekiaris]

although u spoke about the client app does not start is not clear does it start in your dev machine?

[apobekiaris]

can u repro it in an empty XAF solution having installed and register the XpandChartWinModule?

add the XpandSystemWin module to it please and try again

[apobekiaris]

or even better if u still fail to repro it add all the modules u have in your main app and try again.

[apobekiaris]

we need to trace it down in a repro sample, so we can tell what to blame and act accordingly

Closing issue for age. Feel free to reopen it at any time.

.Thank you for your contribution.
