+      For compatibility, the property <InterceptorsPreviewNamespaces> can be used as an alias for <InterceptorsNamespaces>.
+      If both properties have non-empty values, they will be concatenated together in the order $(InterceptorsNamespaces);$(InterceptorsPreviewNamespaces) when passed to the compiler.
+      为了兼容性，属性 <InterceptorsPreviewNamespaces> 可用作 <InterceptorsNamespaces> 的别名。
+      如果两个属性都具有非空值，则它们在传递给编译器时将按 $(InterceptorsNamespaces);$(InterceptorsPreviewNamespaces) 的顺序连接在一起。
