✅ Explicit interface implementation

Hi, guys. Maybe it's a stupid question, but can someone explain me, what is explicit interface implementation used for? I heard it can be used if a class inherits the same method from two interfaces or if one class inherits from another one which, in turn, inherits from an interface and the first class should implement it in its own way. These cases seem confusing and unlikely. Probably I don't understand the importance of this concept, so I ask you to tell me about occasions, when it could be useful. Thank you in advance....

✅ remove dotted border around win32 control in wpf?

hello all! im hosting a win32 control (command links) in wpf but on click they have a dotted border. im trying to replicate windows 7's wizards (which didn't have this on click) so i was wondering how i can remove the border? i've seen people suggest WM_CHANGEUISTATE like such:

SendMessage(source.Handle, WindowMessage.WM_CHANGEUISTATE, MakeLong((int)UIS.UIS_SET, (int)UISF.UISF_HIDEFOCUS), 0);

SendMessage(source.Handle, WindowMessage.WM_CHANGEUISTATE, MakeLong((int)UIS.UIS_SET, (int)UISF.UISF_HIDEFOCUS), 0);

where source.Handle is the main window's handle. however, this doesn't remove the dotted border (but it does remove all focus-related visuals from my wpf elements)...

Xunit and database projects

I'm trying to write some integration tests and am having a little trouble setting up the database. I have imported my database as a SQL Server project to my solution and added a project reference from my test project to the database project. I expected that would place the dacpac in the test project's build output directory, but that's not the case. The dacpac is in the database project's build output directory, but only a dll and pdb in the test project's. I need the path to the dacpac so I can programmatically deploy it to the test environment when tests run. Seems to me I should be able to get it in the test project's output directory, but if there is another/a better way to do this, please lmk!...

NEED HELP

Hey can someone have a look at my code I made this applicaiton a files ago and currently over the year of increasing the amount of files in select image folder it seem to have caused the application to freeze quite often. Base on what I have seen on the code it should be an issue where I havn't limit how many files the btnPickFolder_Click scan for since the freeze issue tends to happen when I set that file location. I tried adding buffer by making the applicaiton only pre load a set amount of images at a time but I don't believe this will solve my issues. Since thinking about this further this is an issue where the applictaion freezes since it loading too many images from the btnPickFolder_Click location into the applicaiton......
