Errata

Aidan's 9 now? Here you forgot to update the value from 7 to 9.

Note from the Author or Editor:
Yes, at the very end of the 3rd text paragraph, the "(7)" should be "(9)".

"As you use the various .NET Framework technologies (Windows Forms, WPF,WCF, , and so on)..." A whitespace is missing between "WPF" and "WCF" acronyms and after that there's a redundant comma.

"Likewise, y ou'd use Shift-JIS encoding to read a text file produced on a Japanese Windows 95 system into the CLR." There's a whitespace in the word "y ou'd".

The phrase "sooner than later" should be changed to "sooner rather than later."

The phrase "self-cancel itself" is redundant. The phrase should be changed to either "self-cancel" or "cancel itself."

IL code comment: In32 instead of Int32

Note from the Author or Editor:
Correct. In the 3rd comment from the bottom of the page, "In32" should be "Int32"

The following section:

"Optional and Named Parameters"

and the corresponding contents in the book should probably refer to optional and named 'arguments' instead because this adheres to the nomenclature defined in the Visual Studio 2012 Documentation.

See: http://msdn.microsoft.com/EN-US/library/vstudio/dd264739%28v=vs.110%29.aspx

Note from the Author or Editor:
Yes, I agree. The section should be titled "Optional and Named Arguments"

The phrase:

"... that are throwing the exception."

seems incorrect.

Note from the Author or Editor:
It should say "that IS throwing the exception"

Should the phrase:

"... the new thread will process a CannotUnloadAppDomainException ..."

be written as:

"... the new thread will throw a CannotUnloadAppDomainException ..."?

Note from the Author or Editor:
Yes, you are correct.

The type name "MarshalByValueType" is divided by one or more blank spaces: "MarshalBy ValueType".

Note from the Author or Editor:
Correct, the space should be removed between "MarshalBy" and "ValType"

The phrase:

"... because the AppDomain has been created."

should probably be:

"... since the AppDomain has been created."


Note that a similar phrase appears on p515 line1 which may suggest the propagation of a spurious find and replace.

The phrase:

"... or you calculate ..."

should probably be:

"... or you could calculate ..."

The phrase:

"...because the last collection."

should probably be:

"...since the last collection."


Also, on the same line, the phrase:

"...that have had fields change need..."

should probably be:

"...that have had fields changed need..."

I think the phrase:

"As region fills..."

should probably be:

"As the region fills..."

The phrase:

"...don't call any virtual methods..."

should probably read:

"...doesn't call any virtual methods..."

The phrase

"IComparableCompareTo"

seems to be missing a separating space:

"IComparable CompareTo"

I think the sentence:

"The C# compiler requires that a method that implements an interface be marked as public."

should be written as:

"The C# compiler requires a method that implements an interface method signature be marked as public."

Note from the Author or Editor:
OK, your sentence structure is better.

Should the sentence:

"A type parameter can be used as a method's parameter, a method's return type, or as a local variable defined inside the method."

be written as:

"A type parameter can be used as a method parameter's type, a method's return type, or the type of a local variable defined inside the method."

Note from the Author or Editor:
Yes, your proposed structure is better.

Should the following line include a space between the '>' and "fn2" for better readability (as does line 2)?

Func<String, Exception>fn2("") = fn1; // No explicit cast is required here

Note from the Author or Editor:
Yes, a space should be inserted after ">" and before "fn2"

The word "now" in the comment below seems extraneous.

"// Copy a reference to the delegate field now into a temporary field for thread safety"

Also, describing the temporary as a "field" seems to break the book's convention of calling such entities local variables.

Note that these comments also apply to the sample code on p255.

Note from the Author or Editor:
I'd like to change the comment to:
"// Copy a reference to the delegate field into a temporary variable now for thread safety"

I like using NOW because that is what we get with Volatile.Read.

The compound word "callsite" is probably meant to be "call site" since the plural form in the same line is written as "call sites".

The phrase "... behavior or a type..." should probably be "... behavior of a type...".

Should "accessed" be 'accesses'?

Odd pages' footer for pages 443-447 has "nullable" spelled as "nullabe", missing the L.

The end of the sentence reads "...because its inception." It should read "...since its inception."

In Contents at a Glance. On page vi it says Par V instead of Part V.

"WIthDegreeOfParallelism" has to be changed with "WithDegreeOfParallelism", WIth -> With

a white space is needed in second parameter

Note from the Author or Editor:
At the code at the top, there should be:
a space between ?CancellationToken? and ?cancellationToken?.
A space between ?Int32? & ? degreeOfParallelism?.
A space between ?ParallelExecutionMode? & ?executionMode?.
A space between ?ParallelMergeOptions? & ?mergeOptions?.

"...is more efficient that..." should be "...is more efficient than..."
