Do you use MAUI application to open a bitlocker? When you remove antivirus application, MAUI application cannot open the bitlock?

Yes I do. I used MAUI application to open a bitlocker.

When I remove antivirus application, MAUI application cannot open the bitlock.

Can you share code about opening the bit lock?

You can debug your application, when open the bitlock, can you get some error messages in the output window?

Here is the code:

Based on your code, you used WPF not the MAUI, right? If this issue is related to the WFP, I can help you add related tag.

Hi,

Did you build the maui app and test it ?

Leon Lu (Shanghai Wicresoft Co,.Ltd.) 77,181 Microsoft Vendor

Yes, but I have an issue about the following code, MAUI do not have Window, GroupBox and TextBox control. And I cannot open above link about screencast. It is better to share a mini demo that could reproduce this issue.

If this problem needs to be solved urgently, it is recommended to open a support ticket for this. Please contact our paid phone support at MS Support. You will get 1:1 support on that

Create MAUI app in 7 and in button click add this code:

The BitLockerHelper.IsBitLockerVolume located in MAUI folder.

This issue probably a system config issue rather than code, you may be better off opening a support case and working with somebody one-on-one for this.

By the way, if you need to add something to the question, you can edit this post with clear and up-to-date info, please do not to post it in comments.

please do not share full demo here (simple demo that could reproduce this issue is ok), this is public site. In order to prioritize the protection of your personal information, we have omitted the full demo content.
