Known Issues

When debugging your project that uses DuckDB.NET library, you may get the following error: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. The error happens due to debugger interaction with the native memory. For a workaround check out Debugger Options mess up debugging session during Marshalling
