    <p>Instead of using pre-compiler statements (which I don't know if they would work anyway if the client didn't have to recompile after installing your plug-in), I would suggest querying the assembly and trying to instantiate an instance of the class by string as seen here:</p> <p><a href="https://stackoverflow.com/questions/1137781/c-correct-way-to-load-assembly-find-class-and-call-run-method">C# - Correct Way to Load Assembly, Find Class and Call Run() Method</a></p> <pre><code>Assembly assembly = Assembly.LoadFile(@"C:\dyn.dll"); Type type = assembly.GetType("TestRunner"); if (type != null) //Do Something </code></pre> <p><strong>Editing to show Activator call</strong></p> <p>if type is not null then use this to create an instance of the type you want.</p> <pre><code>var obj = Activator.CreateInstance(type); </code></pre>

    1. COThis looks very promising. I found I can get the current assembly using GetExecutingAssembly (untested, there are other options). The problem is, even if I get the type as a variable, intellesnse can't recognize members because the type is System.Type and i can't declare the type because I have to check it first...chicken of the egg. I think the only way forward would be to also use reflection to call the method I need but this is a performance sensitive area. I'll test with singleton and see how it goes, then come and edit this.

    2. CO@Rafe, I think I'm a little confused right? You're calling a type you expect to be there if they've loaded a specific assembly from plug in right? If the assembly reference isn't null and the type isn't null you can assume they've loaded that assembly and can create an instance through Activator that does what you need... I've edit'ed my answer to show the activator call...

    3. COI marked this as the answer because it is the best that can be supplied without becoming situational. Unfortunately I won't be going down this road to supply my own solution because the effort cost to create this is not worth the benefit. For us this would be nice to have but is not critical. It should however be made clear the the simple "Do something" should be replaced by "lots more reflection work goes here". Even if going one level deep to a static method is another step. Going deeper in to instances is quite a bit more code depending on what you need.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
