# Compiler Error CS0112

A static member 'function' cannot be marked as override, virtual or abstract
A static member 'function' in a class or struct cannot be marked as override, virtual, or abstract.

Any method declaration that uses the `override`, **virtual**, or **abstract** keyword cannot also use the **static** keyword.
Any method declaration in a class or struct that uses the `override`, `virtual`, or `abstract` keyword cannot also use the `static` keyword.

Before C# 11, interface members could not combine `static` with `override`, `virtual`, or `abstract`. Beginning with C# 11, interface methods, properties, events, and operators can combine `static` with `abstract` or `virtual` by using `static abstract` or `static virtual`.

For more information, see [Methods](../programming-guide/classes-and-structs/methods.md).
