Errors in creating an in-process extension window

[F-Fede]

Hi,

I'm trying to create an in-process extension window since I have to use a custom WPF control, as my final goal is to implement a custom visualizer that can use the aforementioned control.

Unfortunately, I had little fortune in achieving that, and I'm receiving the following error

I started the implementation by setting RequiresInProcessHosting = true, then, by following the errors the compiler gave me, I first added <VssdkCompatibleExtension>true</VssdkCompatibleExtension> to the project file and then a manifest file (that I copy-pasted from the samples).

I also created a minimal sample that recreates the issue on my side: any hints on why this is happening will be very useful! TestExtension_InProcess_KO.zip

The usage of the RequiresInProcessHosting property as well as other initial hints and link to the base documentation (that I've already checked) have been given to me in another issue here.

I will take a look at your sample, and I will start working on adding a new sample for in-proc visualizers. Once I have more info, I will get back to you!
