CS0019 error in HubSpot.Net.Examples

[emrehoser]

I have clone and tried to run HubSpot.Net.Examples, but there is an error that I cannot solve in HubSpotBaseClient.js file. What is the problem?

Hey @emrehoser,

Digging further into this, I found this stackoverflow discussion: https://stackoverflow.com/questions/8982645/how-to-solve-operator-cannot-be-applied-to-operands-of-t..., it state the following:

"T is a type argument and can be a class or a struct, Thus compiler won't let you perform actions that doesn't exist in classes and structs.

structs don't have the == and != by default(but can be added), this is why the compiler complains.

If you use the where keyword to add a constraint to the type argument, the Compiler will let you use that type\interface method\operators

constrain T to be a class"

As such, could you try something like this:

!entity.Equals(default) --> Reference here: CS0019: Operator '!=' cannot be applied to operands of type 'TEnum' and 'TEnum' where TEnum: Enum · ...

Thank you so much.
