Hi All,

I have created net standard DLL (not a dot net framework) and I am trying to use it in the java application. but while execute build.cmd command i am getting below error
"The type 'System.Object' is defined in an assembly
that is not referenced. You must add a reference to assembly 'netstandard
,"

can anyone please help me what is the solution for that?

Please see the below error message.

Note: I can call Dot Net framework DLL in the java application successfully.

Jni4net does not support dotnet core.

Thank you so much Pavel Savara for your reply.

I would like to Jni4Net only support DotNet Framework?

Is there any other way we can use NetStandard DLL in Java?

Thanks & Regards,
Ashok
