So I am having an issue installing npgsql.dll and mono.security.dll. I've been trying to figure this out for so long... please help. Here are the steps I've done...
In the zip file I've downloaded in step 1, I cannot find Npgsql.dll and Mono.Security.dll anywhere...
I've also tried downloading other zip files that have actually had those files, however, when I try to install them in command (gacutil /i C:...\\Npgsql.dll) I just keep getting the following error:
"Failure adding assembly to cache: ???????????"
In Visual Studio 2017, go to menu Tools-> NuGet Package Manager-> Package Manager Console. Run command:
Install-Package Npgsql -Version 3.2.7
To unstall version 3.2.7... and so on...
More versions are available here: https://www.nuget.org/packages/Npgsql/
you can use installation project : https://github.com/npgsql/Npgsql/releases
download MSI package
Thanks
Another way to obtain the npgsql.dll file is:
The dll will be in your project directory. You will also find the dll in the .nuget package directory.
