For a list of initial property values for an instance of NotSupportedException , see the NotSupportedException constructors. You might consider throwing a NotSupportedException exception in the following cases:. You are implementing a general-purpose interface, and number of the methods have no meaningful implementation. For example, if you are creating a date and time type that implements the IConvertible interface, you would throw a NotSupportedException exception for most of the conversions.

You've inherited from an abstract class that requires that you override a number of methods. However, you're only prepared to provide an implementation for a subset of these. For the methods that you decide not to implement, you can choose to throw a NotSupportedException. You are defining a general-purpose type with a state that enables operations conditionally.

For example, your type can be either read-only or read-write. In that case:. If the object is read-only, attempting to assign values to the properties of an instance or call methods that modify instance state should throw a NotSupportedException exception. You should implement a property that returns a Boolean value that indicates whether particular functionality is available. For example, for a type that can be either read-only or read-write, you could implement a IsReadOnly property that indicates whether the set of read-write methods are available or unavailable.

The NotSupportedException exception indicates that a method has no implementation and that you should not call it. You should not handle the exception. Instead, what you should do depends on the cause of the exception: whether an implementation is completely absent , or the member invocation is inconsistent with the purpose of an object such as a call to the FileStream.

Write method on a read-only FileStream object. An implementation has not been provided because the operation cannot be performed in a meaningful way. This is a common exception when you are calling methods on an object that provides implementations for the methods of an abstract base class, or that implements a general-purpose interface, and the method has no meaningful implementation.

For example, the Convert class implements the IConvertible interface, which means that it must include a method to convert every primitive type to every other primitive type. Many of those conversions, however, are not possible. As a result, a call to the Convert. The method call is not supported given the state of the object.

You are attempting to invoke a member whose functionality is unavailable because of the object's state. You can eliminate the exception in one of three ways:.

You know the state of the object in advance, but you've invoked an unsupported method or property. In this case, the member invocation is an error, and you can eliminate it. You know the state of the object in advance usually because your code has instantiated it , but the object is mis-configured.

The following example illustrates this issue. It's hard to tell without more detail like an actual snippet of error including the way you invoked it, etc. Here are a few more details:. Ah ok. I know very little about this code and didn't realize mpc used the "buildalyzer". Thanks for the extra info. I wonder how the binlog is related to this, and how it is that we've created one that's newer than the API we're using to read it. AArnott I reckon the issue might be that I am still using mpc shipped with version 1.

I'm also stuck using the older mpc build unity has no. If a fix for that can be pushed, that would help a lot. Put a global. This issue is stale because it has been open 90 days with no activity.
