I encountered below error message when profiling  an Winforms based vb.net Application using RedGate Profiler..

 It is related to memory access violation. My Local code instance crashed soon after I clicked 'F5' from Visual Studio Code.

 The System.AccessViolationException  : "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." It is a system file "NativeWindow.cs" from where this exception occured..

Any one having any idea on how this particular error can be resolved  ?

A System.AccessViolationException usually indicates that your application is trying to access memory that it shouldn't be. This can happen for several reasons, such as:

  1. Dereferencing a null or invalid pointer: If you're working with pointers in languages like C or C#, accessing memory through a pointer that hasn't been initialized or has been freed can cause this error.

  2. Interoperability issues: If your application is using interop (calling unmanaged code), ensure that the data types and memory management are handled correctly.

  3. Stack overflow: Excessive recursion or deep function calls can lead to stack overflow, causing this exception.

  4. Corrupt memory: Issues such as buffer overflows or improper memory management can corrupt memory, leading to this error.
