Hi,
I want to delete a particular folder when an application is uninstalled.
1.I have developed the WPF app in VS2022 with .net 6
2.Also added a "Setup" project to create the installer => The installer works fine
3.Now I want to add the "Uninstall" custom action to the setup project.
4.Now I need to add an "Installer Class" to my main project, but in VS2022 there is no such template as an "installer class".
5.Is there any alternative for it ?
6.Please help me out here to do the same ?
Is the directory created by the installer or by the program itself?
@Martin Egli The directory created by the program itself. In the application, when I click on the button, I create a new folder here:-
C:\Users\xyzname\AppData\Local
to save some data
Is your application installed per-user or per-machine?
@RLWA32 per-user
Is the application installed to a folder under ProgramFiles or to a folder in the installing users profile? Also, is the application used by more than one user account on the same machine?
1.yes installed under programFiles
2.single user single machine (only one user login on a single machine, there is no logout option).

Well, since only a single user runs your application there is no reason that I can see why the installer should not create the folder. That way the folder could be automatically deleted when the application is uninstalled. The need for a custom action would be eliminated.
@RLWA32 sorry I think there is a confusion. Folder(directory) which I need to delete on uninstall is the location which is different from app location

The installer created by a Visual Studio Installer Project can create folders other than the one that contains the application's executable. This is done by using the File System Editor. For example, to create a subfolder under C:\Users\xyzname\AppData\Local the following cold be used -
Specify "AlwaysCreate" as True for the subfolder in the property pane.
You can right click on the "File System on Target Machine" Node and under "Add Special Folder" select "Custom Folder" and then use the example in the above image.
For example, the installer created the folder C:\Users\RLWA32\AppData\Local\WpfNet6TestFolder

Add Net Framework class library project to solution that contains your .Net 6 main project.
Your main project does not need to reference that class library.
Custom actions can be referenced by adding the installer class to that class library.
@gekka I have already tried to add one "class library" in my main project and now right click on the "class library" and try to add "Installer class", but there is also not found "Installer class" template. Can you please help me out with the help of screenshots of process to add all things ?
Have you selected .Net Framework class library?
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net6.0</TargetFramework>
<ImplicitUsings>enable</ImplicitUsings>
<Nullable>enable</Nullable>
</PropertyGroup>
</Project>
If you have created a .Net 6 class library, you can edit project file.
@gekka Thank you so much and thanks for your valuable time. Now I got the "Installer Class" template. Now please can you tell how to add this class into "setup project" ? with the help of screenshots
@gekka Thanks a lot.
