c# - What is the difference between these two XAML in workflow foundation? -


came across 2 types of xaml specified in windows workflow foundation, want know differences.

type 1.

type 2.

observation

its not data inside xaml, structure. former root tag activity, , child sequence, while latter starts wide name sequenceworkflowactivity. in workflow foundation explain differences?

the xaml in type 1 4.x version of windows workflow foundation, while type 2 sample 3.x version.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
