consider the sample provided.the utility module common.win is provided by devexpress
There is code in the Common.Win project module that adds an XpandXpoTypeInfoSource for TypesInfo.
This causes an error. I found the following articles on the devexpress website. Domain Components+ Calculated properties + Application Model Dynamic member aliases from Application Model Based on this, I concluded: this class is added in order to add a Calculated properties for the domain component. If you are not going to use Calculated properties in your application, you can remove the addition of XpandXpoTypeInfoSource. Otherwise, we will need more time to solve this error.
Feel free to contact us if you have any questions.
