The exception that is thrown when an invoked method is not supported, or when there is an attempt to read, seek, or write to a stream that does not support the invoked functionality.
Assembly: mscorlib (in mscorlib.dll)
Initializes a new instance of the Message property of the new instance to a system-supplied message that describes the error. This message takes into account the current system culture.class, setting the

Initializes a new instance of theclass with a specified error message.
Initializes a new instance of theclass with a specified error message and a reference to the inner exception that is the cause of this exception.

There are methods that are not supported in the base class, with the expectation that these methods will be implemented in the derived classes instead. The derived class might implement only a subset of the methods from the base class, and throwfor the unsupported methods.
System.IO classes whenever there is an attempt to read, seek, or write to a stream that does not support the invoked functionality.is also thrown by
For scenarios where it is sometimes possible for the object to perform the requested operation, and the object state determines whether the operation can be performed, see InvalidOperationException.

When working with the .NET Compact Framework and using P/Invoke on a native function, this exception may be thrown if:
The declaration in managed code is incorrect.
The .NET Compact Framework does not support what you are trying to do.
The DLL names are mangled on export.
In such a case, check:
For any violations of the .NET Compact Framework P/Invoke restrictions.
For any arguments that require pre-allocated memory. If these exist, you should pass a reference to an existing variable.
That the names of the exported functions are correct. This can be verified with DumpBin.exe.
That you are not attempting to pass too many arguments.
- Check to make sure the method is supported.
There are methods that are not supported in the base class, with the expectation that these methods will be supported in the derived classes instead. If a derived class implements only a subset of the methods from its base class, it will throw aexception for the unsupported methods.
