Globally replace obsolete NLog.WarnException using regular expression

I’ve updated NLog ver 2.0 to 4.3.5. After this I’ve noticed a compiler warning that 
WarnException(msg,exc) is obsolete and should be replaced by Warn(exc,msg)

It could be globally replaced using regular expressions 


Warn($2, $1);

RegEx for credit-card-numbers with spaces/dash delimiters

I’ve used regular expressions from that supports delimiters spaces/dashes, e.g. “3714-496353-98431” or “3714 496353 98431”. (by the way I’ve added Diner’s Club pattern  ((?:30[0-59]|(?:(?:36|38|39)[0-9]))[0-9]{11}) even they are obsolete now)
Unfortunately they use backreferences \1 in individual credit card matches, which doesn’t work if I use alternatives (Visa)|(Master)|(Amex).
I replaced numbered capturing groups with named capturing groups .
Javascript and .Net format for named groups are different. I’ve done initially using ?P syntax
(?<!\d)(?:(4\d{3}((?P[\ \-]?)(?:\d{4}(?P=DelimVI)){2}\d(?:\d{3})?)|(5([1-5]\d{2})(?P[\ \-]?)\d{4}(?P=DelimMC)\d{4}(?P=DelimMC)\d{4})|(3[47]\d\d(?P[\ \-]?)\d{6}(?P=DelimAX))\d{5}))(?!\d)
and then had to translate to .Net syntax
(?<!\d)(?:(4\d{3}(?’DelimVI'[\ \-]?)(?:\d{4}\k’DelimVI’){2}\d(?:\d{3})?)|(5([1-5]\d{2})(?’DelimMC'[\ \-]?)\d{4}\k’DelimMC’\d{4}\k’DelimMC’\d{4})|(3[47]\d\d(?’DelimAX’)[\ \-]?)\d{6}\k’DelimAX’\d{5}))(?!\d)
I’ve tested Javascript syntax in RegEx101 (see, but for .Net I had to use and they are not comparable-RegEx101 is significantly user friendlier.

Global Convertion from MStest Assert to FluentAssertions

I found that FluentAssertions provide more descriptive logs in case of assertion failure.
However most of our test methods use MSTest Assert class.
For example statement
should  be changed to
They can be easily converted with the help of Visual Studio Replace. Just  select “use Regular Expressions”
For example
Search for:   \s*Assert.IsTrue\((.*)\);             replace to:      ($1).Should().BeTrue();
Search for:   \s*Assert.IsFalse\((.*)\);            replace to:      ($1).Should().BeFalse();
Search for:   \s*Assert.IsNotNull\((.*)\);        replace to:   ($1).Should().NotBeNull();
Search for:  (\s*)Assert.AreEqual\((.*),(.*)\);replace to:    $1($3).Should().Be($2);
I’ve used only most common asserts,that we are using,but they can be extended for other asserts.
Example of regular expression can be found on regex101
