+# C#/.NET Formatting
+When writing an `if` condition, always wrap the content of the `if` condition in `{` and `}`.
+
+For example:
+
+Instead of the following:
+```csharp
+if (value == 123)
+    Console.WriteLine("It's 123");
+```
+
+Write the following instead:
+```csharp
+if (value == 123)
+{
+    Console.WriteLine("It's 123");
+}
+```
