"Exception has been thrown by the target of an invocation" error (mscorlib)

I have a website developed in ASP.Net 2.0 that is throwing the error 

"Exception has been thrown by the target of an invocation"

in the production environment. It was not throwing this error in development.

The source is 'mscorlib', and the stack trace says the error at 

System.RuntimeMethodHandle._InvokeMethodFast.

The only thing I've changed since my last upload to production is that I've started using Membership controls (Login, LoginView), and have added a few more stored procedures and tables, etc. The membership depends upon a custom provider I've written.

Anybody have a clue why this could be happening?

I'd suggest checking for an inner exception. If there isn't one, check your logs for the exception that occurred immediately prior to this one.

This isn't a web-specific exception, I've also encountered it in desktop-app development. In short, what's happening is that the thread receiving this exception is running some asynchronous code (via Invoke(), e.g.) and that code that's being run asynchronously is exploding with an exception. This target invocation exception is the aftermath of that failure.

If you haven't already, place some sort of exception logging wrapper around the asynchronous callbacks that are being invoked when you trigger this error. Event handlers, for instance. That ought to help you track down the problem.

Good luck!

The reason was backward compatibility

So I just downloaded the Management Studio 2017 and tried to connect to SQLServer2017.

In my case, this happened due to choosing the option to publish as a single file in VS (.NET 5 console app), once I changed it to publish normally the exception was gone.

I got this error after I tried to add a new controller in the Controller folder but the connection string was placed inside the entityFramework tag in Web.config file.

For me, it happens when there is an internal call to another server and that server is not answering in a logical time or the configuration to call it is wrong. I fixed the problem of connecting to another server, then I received the correct data from that server and the function that was responsible for calling that server is working properly then I do not receive that error.
