WebMar 16, 2013 · The basic idea is that when there is only one generic type parameter, the compiler infers the type. When I add a second, the compiler doesn't infer either (It obviously can't infer the second, but I'm not sure why it can't infer the first). My question is why is the type of the container not inferred? c# generics extension-methods Share WebJan 16, 2015 · type inference works. Specifically local type inference tends to infer the most specific type it can. It would be somewhat odd if omitting the return type declaration had the effect of synthesizing a generic method.
