Consume .NET assembly from classic ASP page

Question

I have an old .net 2005 website that has several asp pages and a problem with an object link to a .net dll. The maintenance task was handed over to me, and the original developer was not found anywhere :( I started with .Net already, so I really can not handle the processing of this damn problem.

In the arrow below, I collect "(0x80131500) The object reference is not installed in the object instance."

Set objCommon = Server.CreateObject("Wrapper.CommonFunctions")
  Dim machineBuilding
--->>>  If objCommon.IsMachineAccount(strLogin, machineBuilding) Then

I have already completed the following steps:

• regasm / tbl / codebase mycomdll.dll
• gacutil / i mycomdll.dll
• copy the file mycomdll.dll to the System32 directory
• From the console, execute issreset
• If your dll is created in the framework 2.0, create the file "dllhost.exe.config" in the system32 directory and put this:

<?xml version="1.0"?> <configuration> <startup> <supportedRuntime version="v2.0.50727"/> <requiredRuntime version="v2.0.50727"/> </startup> </configuration>

6.- Restart IIS with issreset
