My thoughts soon went to using method attributes as it's a kind of metadata, but I'm unsure if there are any for this purpose. Right now, I'm simply using XML comment <remark> tags to tell when a method implements some interface. But this is of course no structured...
I have a populated SqlCommand object containing the command text and parameters of various database types along with their values. What I need is a T-SQL script that I could simply execute that would have the same effect as calling the ExecuteNonQuery method on the command object.

Do you any idea how...

I have a OneToMany relationship in an SQL Server database. When I add the tables to my Linq to SQL diagram (DBML) the relationship comes up as OneToOne. I have other OneToMany relationships which synchronise correctly. Even If I change the cardinality to OneToMany the collection still only returns a single entity. Could this be a bug...
One of our 'frontend' developers keeps requesting from us backend developers that the backend notifies all connected clients (it's a client/server environment) of changes to objects.

I have read that to match a word inside of a string using Regular expressions (in .NET), I can use the word boundary specifier (\b) within the regex. However, none of these calls result in any matches Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", @"\b@p1\b"); Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", @"\bI...

What is the proper way to do this. Here are two options I have but I...
