c# - Working with a .dl_ file in visual studio -

-

i've sent on .dl_ file need reference within visual studio project, have been told .dl_ file contains 1 interface, 1 model , 1 xml file.

i've never worked .dl_ before i'm confused on how go getting such information mentioned above in solution, have googled information not how reference / use it.

i have tried right clicking on references > add reference > browse .dl_ location , tried adding error "could not added. please mark sure file accessible, , valid assembly or com component"

a dl_ file sounds file compressed. microsoft compresses lot of system files on installation media. decompress it, use expand, microsoft command line utility. expand file, open command window , type this:

c:\> cd\ c:\> cd mydirectory c:\mydirectory> expand myfile.dl_ myfile.dll

replace mydirectory whatever directory dl_ file in. create dll file, use normal dll.

another possibility friend renamed file .dll .dl_. lot of email clients not allow send email .dll or .exe attachment. security reasons. common way around rename extension. ask friend if did this.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
