Added a list of frequent mistakes that came to my mind.

 ----
+
+== Frequent Mistakes ==
+
+ * Use `Environment.NewLine` instead of the string constant "\n".
+ * Use `Path.Combine()` instead of string concatenation (with `\` or `/`) to combine directory and file names.
+ * Throw and catch specific exceptions, don't catch generic exceptions ~~`try { ... } catch(Exception ex) {}`~~
+ * Use a finally block to make sure that the state of the program is consistent even when Exceptions are thrown.
+ * Set the mouse pointer back to normal in a finally {... } block.
+ * Use `string.Empty` instead of the string constant `""`;
+ * Use `string.IsEmptyOrNull(a)` instead of `if(a!=null && a!="")`
+ * Check for `InvokeRequired` in methods that manipulate GUI elements in controls.
+ * Instantiate all objects of classes implementing `IDisposable` with the `using(...) { ... }` statement to make sure the object is disposed correctly.
+ * When possible use LINQ syntax instead of extension methods for LINQ expressions.

+== Final Remarks ==
