Description

When i compile in debug my maui 8 app compiles and runs - when i try and compile from the command line using debug it also works but when i try and compile from command line for release it fails:

dotnet build -c Release -f net8.0-android -bl REDACTED.csproj I get 9 different errors (all the same error but 9 different xaml files mentioned)

The process cannot access the file 'C:\share\repomike\REDACTED\obj\Release
\net8.0-android\REDACTED.dll' because it is being used by another process. [C:\share\repomike\REDACTED\REDACTED.csproj::TargetFramework=net8.0-android]

When i open the msbuild.binlog I get the following also: Views\HelpPage.xaml The process cannot access the file 'C:\share\repomike\BellMinderProCell\obj\Release\net8.0-android\BellMinderPro.dll' because it is being used by another process. [C:\share\repomike\BellMinderProCell\bellminderpro.csproj]

Can you share a .binlog of the failure? https://aka.ms/binlog

From the info above, I can't tell what MSBuild target or task the error is coming from. There should also be a C# stacktrace of some kind?

@jonathanpeppers do you have an email address i can send it to as there is a lot of information in that file and would rather not have that on public website.

[michaelonz]

Hi @jonathanpeppers - I have emailed the file to you -thx

[jonathanpeppers]

This this the XamlCTask, so a general MAUI issue:

(It's complaining about the project's .dll file)

@michaelonz do you have some antivirus enabled? Can you exclude the source folder where this project is?

[michaelonz]

This solved my @jonathanpeppers - disabling the virus checker for that folder

[jonathanpeppers]

@michaelonz which antivirus software caused it?

[michaelonz]

@jonathanpeppers - I went into totalav and added a rule to exclude the root of the solution folder and the problem went away.

I guess this is: https://totalav.com/

And with that, I think this issue is resolved. Thanks all!
