Vault 2025 VDF doesn't work in AutoCAD 2025 plugin

[n_Sovljanski]

Hello,

I have very, very strange situation with implementation VDF in AutoCAD 2025 plugin.

1. I use using VDF = Autodesk.DataManagement.Client.Framework;

2. it is used to listen event in Initialize method

public void Initialize()
{
		VDF.Vault.Library.ConnectionManager.ConnectionEstablished += ConnectionManager_ConnectionEstablished;
}

3. With line 3 plugin will not be loaded in AutoCAD 2025. If I commented line 3 plugin will be loaded.

4. everything works fine in AutoCAD/Vault2024

5. There is no compilation error, there is no error, or message from AutoCAD during loading

Does anybody face this issue?

It is solve  by Autodesk support team. If you want to use libraries for Vault 2025 then:

1. Find setup.exe in C:\Program Files\Autodesk\Vault Client 2025\SDK

2. Run Setup.exe and wait to finish job.

3. find folder C:\Program Files\Autodesk\Autodesk Vault 2025 SDK\bin\x64\core

4. in That folder you can find all libraries developed in NET8
