Unclear errors on field with ObservableProperty

[elad770]

Describe the bug

I have a wpf (core based) project, with net6.0 (with visual studio 2022 enterprise), where I installed from nuget the toolkit mvvm version 8.0.0. In the project I have a very basic class that is defined as partial and inherits ObservableObject (just like any guide that explains how to work with the toolkit's MVVM) and contains 3 fields each wrapped respectively in an ObservableProperty attribute. When I try to compile I get errors that I have no idea why they actually happen, the errors actually refer to cs g files that are dynamically created using the toolkit, I will give an example for example I have a field in the basic class (called AstroInfo) called star and on it I get an error below that directs it to the g.cs file The type 'AstroInfo' already contains a definition for 'Star' In addition to this, more unclear errors in relation to functions that describe events such as 'AstroInfo' already defines a member called 'OnStarChanging' with the same parameter and- A partial method may not have multiple defining

I would appreciate guidance in this regard

Mmh @manodasanw I wonder if this sounds similar to that issue you noticed with the CsWinRT generators running multiple times in WPF? I can't think of another explanation for those errors otherwise 😐

@elad770 would you be able to provide a binlog?

That is, build with -v:diag /bl and share the file. Thank you!

@Sergio0694 It is not possible to upload bl or rar files here, just change the extension of the file to bl Thank you very much msbuild.txt
