Add references to the client and server runtime assemblies with NuGet.

See topic NuGet

Right-click "Dependencies" (ASP.NET Core) or "References" (ASP.NET) in the Solution Explorer and select "Manage NuGet Packages".

Select the "Browse" tab and search for "venturasql".

Select VenturaSQL.AspNet or VenturaSQL.AspNetCore depending on the project type and click [Install].

The package will be downloaded and a reference will be added to the project. 

As the server runtime package holds a reference to the client runtime package, the package VenturaSQL.NETStandard will automatically be downloaded and referenced too.
