我想将 SQL Server 2019 连接到 Unity？ 如何摆脱这些错误？ 统一2019.2.11f1

Question

I have downloaded .dll files too and added them to assets folder in unity2019.2.11f1 but that didn't work.

Answer 1

You need to move the.dll files to a "Plugins" folder.

Alternatively, you could just set your project's Scripting Runtime Version to ".NET 4.X Equivalent" and all references should be added automatically after Unity restarts.
