Lao Sen Chang Tan IT Help

Completed "AD password verification"and"AD password change》After two APIs，Next, use .NET MAUI Blazor to write desktop programs。After learning a little about Blazor，I feel so magical，It feels like putting a web page into an application，When running, you can also see Edge-related components running behind it in the "Job Manager"，Then press F12 and there will be a developer tools window! But this also gave me some security concerns.。But the overall feeling is quite special.，I happen to be familiar with web page syntax，Use Razor to design UI screens，Feeling more friendly。

The structure of the program is two pages，The first page is AD password verification，After passing, you will be directed to the AD password change page.。

"Project Template"

• .NET MAUI Blazor App

"Suite"

• bootstrap
