Hi,

 

I am getting the following error, on running the client program (C# console) target with .NetCore 3.1 and referencing .Net SDK 5.8. I am following SteamSensor  example

 

Kindly let me know on it's limitation to .Net framework only..? Also guide me to resolve the issue, if supports .Net Core 3.1.

 

"Unable to find an entry point named 'CopyMemory' in DLL 'kernel32.dll'."

at com.thingworx.communications.common.SecurityClaims.CopyMemory(IntPtr destination, IntPtr source, UInt32 length)
at com.thingworx.communications.common.SecurityClaims.twCopyMemory(IntPtr destination, IntPtr source, UInt32 length)
at Thingworx_RemoteThing.RemoteThingClient.<>c__DisplayClass4_0.<Main>b__0(IntPtr password, Int32 maxLength) in PoC\Thingworx_RemoteThing\Program.cs:line

Hi @gvyakaranam 

 

Thank you for reaching out to us. I believe this issue is occurring form .NET side. Can you check below thread.

@mgoel 

It seems modification of the entry point in SecurityClaims.cs (thingworx-dotnet-common.dll) for method twCopyMemory() or any internal static method like mentioned below.

 

[DllImport("kernel32.dll", EntryPoint = "RtlMoveMemory", SetLastError = false)]
public static extern void CopyMemory(IntPtr dest, IntPtr src, uint count);
