+## error C2471: cannot update program database
+
+MSBuild has trouble writing files to a mounted directory which occurs even if the out path is set in the project.
+It is recommended that you include a script in your project that copies the `C:\source` directory into the container prior to running the build commands.
+
+```powershell
+Copy-Item $source_path -Destination $build_path
+Set-Location -Path $build_path
+MSBuild project.sln
+Copy-Item $build_path -Destination $out_path
+```
