I'm writing an extension that reads serial port data. I'm running on BC14 OnPremis.
Here is what I have. The global variable, running on client side (obviously serioal port is not on the server, with events because I need to receive data somehow.
var
[RunOnClient]
[WithEvents]
Port: DotNet SerialPortA;
The trigger which is called when data on port is available. It is actually fired.
trigger Port::DataReceived(sender: Variant; e: DotNet SerialDataReceivedEventArgs)
var
CurrPort: DotNet SerialPortA;
BarText: DotNet String;
begin
CurrPort := sender;
BarText := CurrPort.ReadLine();
Message(BarText);
end;
In the dotne.al file I have a declaration for SerialPort type. For some reasons it confused name with something else so I had to add a suffix to type alias. So now my type is called SerialPortA.
assembly("System")
{
Version = '4.0.0.0';
Culture = 'neutral';
PublicKeyToken = 'b77a5c561934e089';
type("System.IO.Ports.SerialPort"; "SerialPortA") { }
type("System.IO.Ports.SerialDataReceivedEventArgs"; "SerialDataReceivedEventArgs") { }
type("System.IO.Ports.SerialErrorReceivedEventArgs"; "SerialErrorReceivedEventArgs") { }
}
The problem is that a call to CurrPort.ReadLine() fails with error:
A call to System.Object.ReadLine failed with this message: The type of one or more arguments does not match the method's parameter type.
I tried to use another method Read. The error is the same. It is most probably related to Nav wrapping/unwrapping all dotnet variables to object type, but I don't know what ca I do with thath. Any guess what is going wrong here?
In the event log there is an error description

I don't have a serial port to test with, so this is of the top of my mind.
You probably need to cast the variant to the correct type:
trigger Port::DataReceived(sender: Variant; e: DotNet SerialDataReceivedEventArgs)
var
Type: DotNet Type;
Convert: DotNet Convert;
CurrPort: DotNet SerialPortA;
BarText: DotNet String;
begin
// This check is just best pratice, but not needed in this case as we know sender is a SerialPort.
if not sender.IsDotNet() then
exit;
Type := GetDotNetType(sender);
CurrPort := Convert.ChangeType(sender, Type);
BarText := CurrPort.ReadLine();
Message(BarText);
end;
I am working in Visual Studio 2015 using Visual Basic. I am connecting to a PostgreSql database using Npgsql. There seems to be a problem with the Array Datatype - or hopefully I am doing something wrong. Some of my code:
Dim aWriter As Npgsql.NpgsqlBinaryImporter
Dim Keys() As String
N_Domain = UBound(myKey_Name, 1)
N_Record = UBound(myKey_Name, 2)
ReDim Keys(0 To N_Domain - 1)
aWriter = Connect.BeginBinaryImport _
("COPY ""GAMS Sets"" FROM STDIN (FORMAT BINARY)")
For Rec = 1 To N_Record
For Dom = 1 To N_Domain
Keys(Dom - 1) = myKey_Name(Dom, Rec)
Next Dom
aWriter.StartRow()
aWriter.Write(myCase, NpgsqlDbType.Text)
aWriter.Write(SyId, NpgsqlDbType.Text)
aWriter.Write(Keys, NpgsqlDbType.Array Or NpgsqlDbType.Text)
Next Rec
aWriter.Dispose()
aWriter.Close()
When I run the code I get an error at aWriter.Dispose():
{"42804: wrong element type"}, ErrorCode: -2147467259.
What is wrong? Isn't Text Arrays supported?

InnerException:
I have written a PowerShell script that requires passing large byte arrays between functions. The script runs extremely slowly. The sample code below reproduces the problem. It simply passes a 10 MiB array into a function that does nothing (other than log a message), and measures how long the call takes.
function do-nothing
{
param($foo)
Write-Verbose -Verbose "in the function"
}
$tenMiB = 10 * 1024 * 1024
$myFoo = New-Object byte[] $tenMiB
Write-Verbose -Verbose "about to do call a function that does nothing..."
$elapsed = Measure-Command -Expression { do-nothing -foo $myFoo }
Write-Verbose -Verbose "doing nothing took $($elapsed.TotalMilliseconds) milliseconds"
I expect this to take a few milliseconds. On my home PC it takes nearly 3000 ms and runs a CPU core at 100%. I get the same result with PowerShell 4 and PowerShell 5 (pre-production version). The same thing happens with my work PC and servers. However, one colleague gets the expected result - a few milliseconds to execute, minimal CPU usage.
The execution time is roughly proportional to the size of the array, which makes no sense to me. The size of the array should not matter.
I wondered if the array was somehow being copied. I do not think this is the case because calling GetHashCode() on the array returns the same value inside and outside of the function.
If the array is wrapped in a PSCustomObject, and the wrapper is passed to the function, then the code performs as expected. This is a bit ugly as a workaround, and I'd rather understand what is going on before resorting to it.
Can anyone explain this seemingly weird behaviour please?
I'm posting this as a community wiki, intended to be a place where we can post our individual environments and test results, since there seems to be some trouble reproducing. Maybe we can figure out the conditions that cause this, and from there determine why it's slow in the instances that it is. Formatting suggestions / changes welcome.

Thanks to stack traces posted by #Ansgar Wiechers, I was able to reproduce this behavior on my PC (Windows 10 build 1511, PowerShell 5.0.10586.0) with following code:
$Module = New-Module {
function do-nothing
{
param($foo)
Write-Verbose -Verbose "in the function"
}
}
$Module.LogPipelineExecutionDetails = $true
$myFoo = New-Object byte[] 10mb
Write-Verbose -Verbose "about to do call a function that does nothing..."
$elapsed = Measure-Command -Expression { do-nothing -foo $myFoo }
Write-Verbose -Verbose "doing nothing took $($elapsed.TotalMilliseconds) milliseconds"
Enabling LogPipelineExecutionDetails cause large slowdown of function execution. Judging from my digging with ILSpy, logging of pipeline execution details should be enabled only if function belong to module and module enable this option. Maybe that is exact behavior which kb3000850 altering.
It would be interesting to see if problem reproduced when do-nothing belong to module, but LogPipelineExecutionDetails explicitly set to $false.
Supplementary information, posted as an additional community wiki answer to avoid the character limit per answer.
As requested by #PetSerAl I ran the following code before and after installing kb3000850:
Add-Type -TypeDefinition #'
public static class C{
public static System.Collections.IEnumerable M(){
System.Console.WriteLine(new System.Diagnostics.StackTrace());
yield break;
}
}
'#
function do-nothing {
param($foo)
Write-Verbose -Verbose "in the function"
}
$myFoo = [C]::M()
Write-Verbose -Verbose "about to do call a function that does nothing..."
$elapsed = Measure-Command -Expression { do-nothing -foo $myFoo }
Write-Verbose -Verbose "doing nothing took $($elapsed.TotalMilliseconds) milliseconds"

You cannot reuse the same UIElement instance for different parts of the UI. Either remove it from the first and add it to the second one (not recommended but there are some advanced scenarios were it makes sense) or simply create a new one. It's pretty cheap.
I had this error, and I managed to work out exactly why it was occurring using trial and error.
The problem? I was using the following line of XAML in both context menus for a master/detail grid, using the DXGrid from DevExpress.
<dxb:BarItemLinkSeparator />
Once I the issue was fixed, I noticed that the stack trace did actually give a small clue as to which XAML element was causing the error. The 4th line in the stack trace ends with this:
[snip]ILinksHolder.OnLinkAdded(BarItemLinkBase link)
BarItemLinkBase is the base class for BarItemLinkSeparator, which is our clue that removing said XAML will fix the error.
For context, here is the full stack trace:

I'm using the following code to dynamically add columns to my GridView:
public void AddGridViewColumns()
{
GridView view = (GridView)_myListView.View;
GridViewColumn column = BuildGridViewColumn(1);
view.Columns.Add(column);
}
public virtual GridViewColumn BuildGridViewColumn(int blockIndex)
{
string templateXaml = string.Format(
#"<DataTemplate
xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation""
xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml""
xmlns:local=""clr-namespace:Pse.MyTest;assembly=MyTest"">
<DataTemplate.Resources>
<local:BlockToBrushConverter
x:Key=""_blockToBrushConverter"" />
</DataTemplate.Resources>
<TextBlock
Style=""{{StaticResource _gridViewCenterItemStyle}}""
Text=""{{Binding Path=Block{0}.ConditionLabel}}""
Foreground=""{{Binding Path=Block{0}, Converter={{StaticResource _blockToBrushConverter}}}}"" />
</DataTemplate>",
blockIndex);
System.Diagnostics.Debug.Print(templateXaml);
GridViewColumn column = new GridViewColumn();
column.Header = string.Format("Block {0}", blockIndex);
column.CellTemplate = (DataTemplate)XamlReader.Parse(templateXaml);
return column;
}
The Debug.Print results in:
<DataTemplate
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

</DataTemplate.Resources>
<TextBlock
Style="{StaticResource _gridViewCenterItemStyle}"
Text="{Binding Path=Block1.ConditionLabel}"
Foreground="{Binding Path=Block1, Converter={StaticResource _blockToBrushConverter}}" />
</DataTemplate>
When I run it, it says it cannot find _blockToBrushConverter.
The exception is:
System.Windows.Markup.XamlParseException was unhandled
Message="Cannot find resource named '{_blockToBrushConverter}'. Resource names are case sensitive. Error at object 'System.Windows.Data.Binding' in markup file 'MyTest;component/SetupWindowDictionary.xaml' Line 23 Position 13."
Source="PresentationFramework"
LineNumber=23
LinePosition=13
NameContext="Foreground"
If I remove the Forecolor attribute, the XAML parses just fine (and I get the expected results). It seems like including the converter in DateTemplate.Resources should guarantee that it would be found, but for some reason it isn't.
I also tried moving the declaration for my converter resource higher in the tree (to the Window level), but that didn't work either. It seems to be able to find "_gridViewCenterItemStyle", but for some reason, it refuses to find the converter.
Any ideas greatly appreciated.
Here's the entire exception with stack trace in case it helps:
System.Windows.Markup.XamlParseException was unhandled

EDIT:
Problem solved: I did a search through my whole project and noticed I had an extra copy of the BlockToBrushConverter resource declaration with same x:Key in one of my resource dictionaries. Once I eliminated the duplication, the problem disappeared.
Just in case someone else takes a look at this question someday, it turns out, the code I presented at the top of this question actually works. The bug was that I had the following declaration elsewhere in my XAML:
<local:BlockToBrushConverter
x:Key="_blockToBrushConverter" />
I believe this duplication prevented the resource from being declared locally for the dynamic DataTemplate (it couldn't create a resource with the same name twice within the same context).
One thing that is sort of unresolved for me is why some StaticResources need to be declared locally, while others (like the _gridViewCenterItemStyle StaticResource) can be declared higher in the tree (such as at the Window level) without a problem.
