Thanks @mikeirvingweb ... Note in passing tho that new samples are created from the Blazor project templates each release. The images here named image1.png, image2.png, and image3.png will be copied, so your updates here will be forwarded each release into the new sample apps. However, the rest of your icon/favicon changes won't be forwarded because they come in from the new template. If you want to see about making these changes for the Blazor framework, you'll need to open an issue for the product unit and suggest it to them offering to take on the task if you wish ... if you'd like to proceed, open an issue here ...
