Open axaml Designer make a project build fail in Visual Studio 2022

[afluegge]

Describe the bug

When the axaml Designer is open at least once and I try to build the project, the build fails.

To Reproduce

Steps to reproduce the behavior:

1. Open any axaml file to start the Designer
2. Start a build
3. After some time the build fails:

Error MSB3027: Could not copy "obj\Debug\net8.0\MyProject.dll" to "bin\Debug\net8.0\MyProject.dll". Exceeded retry count of 10. Failed. The file is locked by: ".NET Host (9652)" (4735, 6)

Expected behavior

The build just goes through....

Environment

• OS: Windows 11
• Avalonia-Version: 11.0.7
• Visual Studio 2022 (17.8.4)

Any updates on this? It's really frustrating to have to make sure to close all axaml files before running/building the project.... could we at least get an option to disable the preview of the designer? I'm assuming that's what causes the build issues...

Latest findings: when ReSharper build is enabled the described problem exists. When deactivating ReSharper build and use the default Microsoft build the problem does not exist. This is when using the latest Avalonia versions.

Thank you for the update, that's really helpful as I do have ReSharper build enabled. I will disable it, I rather not have to close designer windows than have a nice visual of the build. 👍🏼
