Workflow Foundation BRE missing Regex

Question

I'm using WF BRE and try to use regex in rule condition. But there is no regex. The namespace System.Text.RegularExpressions does not exist, neither the Regex.Match method. I tried to add:

using System.Text.RegularExpressions;

to my Rules Designer Application but that didn't work.

I get the "Rule Set Editor: Error parsing the Action(s): The identifier "Regex" could not be resolved." error.

How can I add regex to BRE?

@stribizhev Reference to System is added. I can't add reference to System.Text or System.Text.RegularExpressions. — JKL, Jul 15 '15 at 09:56
@stribizhev as I wrote before, there is reference to System. You can't add there reference to System.Text or anything below that. — JKL, Jul 15 '15 at 10:53

If anyone has the same issue. This is how I resolved it.

Created a method on class that entere the flow

public bool CheckPattern(string pattern, string value)
    {
        Regex regex = new Regex(pattern);

        return regex.IsMatch(value);
    }

And in Rule entered:

this.CheckPattern("myRegexPattern", myEmail)
