+# Compiler Error CS8141
+
+The tuple element names in the signature of method must match the tuple element names of interface method (including on the return type).
+
+## Example
+
+ The following sample generates CS8141:
+
+```csharp
+// CS8141.cs (10,27)
+using System.Collections;
+
+public interface IGrabber<out T>
+{
+    T GetOne();
+}
+
+class SomeGrabber : IGrabber<(int, int)>
+{
+    public (int a, int b) GetOne()
+    {
+        return (1, 2);
+    }
+}
+```
+
+## To correct this error
+
+Changing the signature of the `GetOne` method to return an unnamed tuple, matching the unnamed tuple in the interface, will correct this error:
+
+```csharp
+    public (int, int) GetOne()
+    {
+        return (1, 2);
+    }
+```
