C# Edit and Continue: error 4013
Updating the size of a fixed field will prevent the debug session from continuing while Edit and Continue is enabled
This error indicates that you tried to edit the size of a fixed-size buffer, which cannot be changed while debugging.
For example, consider the following code:
unsafe struct Example
{
fixed int buffer[20];
}
class Program
{
static void Main() { }
}
If you step into Main, then try to change buffer(20) to buffer(10), this error occurs.
To correct this error
- On the Debug menu, click Stop Debugging, make the changes, then start a new debugging session.
