When you get this error, it means that code you are using makes a reference to an type that is in an assembly, but the assembly is not part of your project so it can't use it. Deleting Project.

An “Undefined Reference” error occurs when we have a reference to object name (class, function, variable, etc.) in our program and the linker cannot find its definition when it tries to search for it in all the linked object files and libraries. ... There are various reasons that cause an “undefined reference” error.

To fix this error, you will either need to remove the call to Object. preventExtensions() entirely, or move it to a position so that the property is added earlier and only later the object is marked as non-extensible. Of course you can also remove the property that was attempted to be added, if you don't need it.

The type or namespace name 'type/namespace' could not be found (are you missing a using directive or an assembly reference?) A type or namespace that is used in the program was not found. ... Or, there might be an issue with the assembly you are trying to reference. The following situations cause compiler error CS0246.

Possible causes for this error include the following: An assembly that contains the definition of a type was not referenced in the compilation; use -reference (Import Metadata) to specify the assembly. You passed a variable name to the typeof operator. You tried to reference an assembly that is not part of your target ...

You can: int&& x = 3; x is now an lvalue. A so called 'rvalue-reference' can bind to a temporary, but anything with a name is an lvalue, so you need to forward<>() it if you need it's rvalueness back.

a using directive or an assembly reference?) The CS1061 error is caused when you try to call a method or access a class member that does not exist. The example below shows the method SayGoodbye being called through Class1. As we can see Class1 does not contain a definition for the method SayGoodbye.

References are used to refer an existing variable in another name whereas pointers are used to store address of variable. References cannot have a null value assigned but pointer can. A reference variable can be referenced by pass by value whereas a pointer can be referenced but pass by reference.

A symbol remains undefined when a symbol reference in a relocatable object is never matched to a symbol definition. Similarly, if a shared object is used to create a dynamic executable and leaves an unresolved symbol definition, an undefined symbol error results.

It means that you have a module installed in your local npm repo that is "extraneous" (meaning you have no dependency on it) that has an "unmet peer dependency" on a library you also do not have installed (or if you do have it installed locally or globally, it is also extraneous so it's not in your dependency tree).

Keyword extern is present exactly for the same reason. You can tell the name and type of variable followed by extern which means this variable is present in one of the (possibly current) compilation unit which will be resolved (linked) at link time. Global talks about the visibility of a variable (or function).
