+# Unsupported features
+
+## Context
+
+In order to keep true to how mocking works some features will not be supported.
+
+## Decision
+
+**Extension methods** are not supported due to their nature. Extension methods are static methods that are called as if they were instance methods of the extended type.
+
+**Sealed classes** are not supported since they can not be inherited from and such do not fit how the framework works.
+
+**Static members** and **Static classes** are not supported due to the way the framework works.
+
+## Consequences
+
+### Positive:
+
+- **No need for magic**: Mocking these features would require breaking the standard supported functionality. 
+
+### Negative:
+
+- **No magic**: Some functionality can be harder to test but if you need to test this maby you have some other issues.
