+# Write-Information writes nothing in ForEach method
+
+For some reason (a bug?), `Write-Information` writes nothing in `.ForEach({...})` method script blocks.
+
+See [Test-1.ps1](Test-1.ps1). It shows the problem in `.ForEach({...})` and
+also shows that `Write-Information` works fine in `| .{process{...}}` and `|
+ForEach-Object {...}` script blocks.
