## How to identify the conflicting assemblies

The full error message shows which assemblies contain the conflicting type. The message format is:

```
error CS0433: The type 'N.C' exists in both 'A, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' and 'B, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'
```

In this example, the conflicting assemblies are **A** and **B**. The assembly names appear in single quotes before the version information. Use these assembly names to determine which references are causing the conflict and decide how to resolve it.
