Intellisense not recognizes extension methods for generic classes from .NET Standard 2.0 references
This issue has been moved from a ticket on Developer Community.
[severity:It’s more difficult to complete my work]
I have a .NET Standard 2.0 Library in which I have defined this extension class.
public static class MyExtension
{
public static void ExtendEnumerable<T>(this IEnumerable<T> items) { }
public static void ExtendTObject<T>(this T tObject) { }
}
There is a second .NET 8 project which references the .NET Standard 2.0 library. From whithin the .NET 8 project Intellisense doesn’t recognize ExtendEnumerable<> when the namespace is not already imported. It does tho recognizes ExtendObject<> and it also recognizes MyExtension class and imports the using properly.
Visual Studio option Text Editor > C# > Intellisense > Show items from unimported namespaces is enabled.
I provided a little sample project which contains the same extension class defined in 3 different frameworks. While ExtendTObject<> gets recognized correctly, ExtendEnumerable<> does so only for . NET6 and . NET8 libraries. See screenshot below:
