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!

This can happen when invoking a method that doesn’t exist.

I know its kind of odd but I experienced this error for a c# application and finally I found out the problem is the Icon of the form! when I changed it everything just worked fine.
I should say that I had this error just in XP not in 7 or 8 .

Encounter the same error when tried to connect to SQLServer2017 through Management Studio 2014
The reason was backward compatibility
So I just downloaded the Management Studio 2017 and tried to connect to SQLServer2017.

I just had this issue from a namespace mismatch. My XAML file was getting ported over and it had a different namespace from that in the code behind file.

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.

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.

I had the same problem.
I was trying to create a report from C# and it wasn’t checking if the field is empty or whitespace.
I add Exception.

When debugging and no InnerException found it can be handy to hit F5 (continue) until it hits another Exception. Or if it drops out entirely you can then check the Output window for more details.

I have a winforms application which was working fine. Recently i formatted my system and reinstalled VS 2008. From that time the application has stopped running.
When i run it through VS it gives error
«exception has been thrown by the target of an invocation.»
I went on to debug and found that in the this exception comes when from c# code using reflection the code tries to invoke a function from an assembly which is written in c++.
Updated 20-Sep-22 21:08pm
Eventually I solved this myself. It was just a matter of getting to the root of the problem.
Actually the cuase of this exception was another exception which occured inside the method being invoked.
So i went to look out for solution by searching the exception ex.innerexception .
From there i searched the stack trace of that exception to finnaly get to the root of the problem.
So anyone getting this error do look for the innerexception cause the real problem lies there.
Thanks,
Mateen
for the said error, we are talking about inner exception. How to get this inner exception?
running bat «${NUGET_HOME}/nuget.exe restore Dotsolution.sln from jenkins file and getting this error:
Error parsing solution file at D:JenkinsworkspaceDotsolution.sln: Exception has been thrown by the target of an invocation.
Disable the ajax for a moment (EnablePartialRendering=»false» on the scriptmanager).
we Got Exception aftr that delete EnablePartialRendering property.
Great said by Mateen Khan, you need to understand what is you controls default value..
eg i’m using combobox in silverlight and i was trying to bind its selected index
as a default its selected index was -1
but it was get nothing from the respective property …
I looked inside the inner exception and find out my solution

Summary
When starting the RESTAPI.exe program, ?Exception has been thrown by the target of an invocation? error is displayed
Objective
Resolve ?Exception has been thrown by the target of an invocation? error when starting RestAPI.exe in ICM10 on-premise installation
Environment
Incentive Compensation Management version 10
Steps
After installing and making the basic configuration to RestAPI.exe.config file, double clicking on RESTAPI.exe file to start the program results in the following error:
Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. —> System.Net.HttpListenerException: The process cannot access the file because it is being used by another process

This error usually occurs when RestAPI port is conflicting with another process that uses the same communication port. In most of the cases, this is the web server Apache, which is many time configured to use port 8080.
To solve this there are two ways:
1. Go to your Apache installation directory and then ‘conf‘ folder (e.g. C:Program Files (x86)Apache Software FoundationApache2.2conf) and open httpd.conf file.
2. Change the port number within the following line:
Listen 8080
to
Listen 8081
3. Save the file
4. Restart Apache web service
5. Restart RESTAPI.exe. The service is working now.

Some quick solutions if you don’t want to read the story:
- Check if package variables referenced in script task are correct
- Check if package variables are being set correctly outside of the script task
- Check if the script task’s references match up with the server’s framework
- My issue: check if you have permissions
Back to my story:
The other day, one of the packages I maintain broke in nearly every region it was deployed to. I’m thinking “Omg, why?” since this process has never failed in the years it has been implemented. So, I looked at the log to find the descriptive error message : “Exception has been thrown by the target of an invocation”:
I’m thinking, “Cool, I’ve seen this before, it should be easy“. So I go through the code to trace it to where it was bombing out, then I go through the routine of debugging the common issues:
- Check if package variables referenced in script task are correct – nope!
- Check if package variables are being set correctly outside of the script task – nope!
- Check if the script task’s references match up with the server’s framework – nope!
Nothing seemed to be off in the cases. Eventually, I assume that it has to be a security issue – because that seems to be the solution to everything for me. I run the process in a dev server to find that everything is fine. Now I’m like “Seriously?!“.
Frustrated, I end up wrapping the code in a try catch to print out the error and deploy:
Ah, I knew it! Unauthorized access:
Short story, I looked at previous versions of the directory to find the security had changed. I end up getting permissions added for the users, and ta da! Worked like a charm.
Lessons learned:
- Think outside the box. How the heck would someone think it’s a security issue from “…target of invocation”?
- Better error handling
- Don’t forget to rollback the changes you deployed to quickly find out what was going on since it’s not really good code and you could get in trouble for it
Hopefully that helps! Happy coding!

We are running SQL Server 2014, but I am not quite sure how to check SSMS without being able to start SSMS.
Also, as you might already have guessed, I am not exactly what you would call a SQL expert, how would I repair SSMS?
A side note, my server is located on a location with very bad internet connection (384 kbps down, 128 kbps up), so it makes it a bit difficult to make large downloads.

One question: Are you running SSMS locally on your machine or are you using remote desktop and opening SSMS on the VM?
Okay, two: Did you confirm operation of the SQL Server instance on the VM after the upgrade?
If you go into Programs and Features and look for Microsoft SQL Server Management Studio, it should tell you the version. You may also be able to do a repair install from there (needs local admin rights). Right-click on SSMS and select repair if it gives you that option or uninstall if not. The installer should give you an option to do the repair.

I am connecting to the SSMS on the server, which is hosting the databases.
The databases are working after the upgrade. Only other issue we encountered were that the SQL Server service was Disabled.
When searching for Server Management Studio in the «Programs and Features» there are no records.

Your best bet is a re-install of SSMS from your installation media (SSMS is a separate product now but I don’t remember when MS made the split).
You could download SSMS 17 and install that as well.

Newer versions of SSMS (don’t remember exactly when MS did the switch over) are built on top of Visual Studio and require .NET, so that could easily be the source of the SSMS problem.
