Useful things I have made that someone may want.
MS/Bootstrapper/DotNetFX48 This is a working copy of the Microsoft bootstrapper manifest for .net 4.8 redist. the one supplied in SDKs is buggy. This can also be used for clickonce.
MessageBoxManager/MessageBoxManager.cs This is a version of the winforms messageBOx customization class that works with dotnet (i tried it with 8).
