Hi,
In my current project I introduced DynamicPlaceholders.Mvc to replace a Legacy DynamicPlaceholders implementation. The change to DynamicPlaceholdersRegex introduced in version 1.2.0.2 do not produce a match for PlaceholderKeys containing whitespaces. In my opinion, whitespaces should never be used in placeholder keys. In my current project, some PlaceholderSettings were initially set up this way. Now I have to deal with it.
You could extend the regex to handle those cases as well.
([a-zA-Z0-9\s_-]+?)_[\d\w]{8}\-(?:[\d\w]{4}\-){3}[\d\w]{12}(?:_.+)?$
What do you think about it?
Best Regards, Maik
