MonoDevelop-Unity: Unhandled Exception.

Yesterday everything was fine, but starting today all I get is this error message and I can't open any document at all anymore.



The only difference was that I pulled a GIT update this morning adding some source files to the project, but it shouldn't affect Monodevelop-Unity itself.



The details in the Error message:

I'm having exactly the same problem. I can't open any file in MonoDevelop, and I get exactly the same exception, with exactly the same stack trace.

For me, this is the first time I've ever opened the project on this computer, but it worked fine on the computer where I first developed it. The only difference for me is that it was originally created on a trial version of Unity Pro, and I'm currently working with the free version.

 

I added this problem to Unity Answers, since it's more likely to be noticed there: http://answers.unity3d.com/questions/390738/monodevelop-uncaught-exceptions.html

Also, I discovered that (at least on my machine) this problem isn't limited to just opening files. If I attempt to open the VersionControl dropdown menu, it produces a ton of exceptions and crashes. Can you verify this?

And another question. Were you using github?

 

I think this is the same problem: http://answers.unity3d.com/questions/350327/cant-open-c-files-in-monodevelop-after-moving-proj.html

 

And here's the workaround:

 

Ahh thanks for that, yes it fixed it. I already installed Unity again today but it didn't fix it, disabling the GIT support plugin in monodevelop did.

 

Yay.

Thanks for letting me know. I appreciate it.

 

I was about to paste the reply in your unity Aswers thread but the Unity servers have some issues of late with my Answers account (claim bug). Maybe mark that one as resolved yourself, I am sure some people will search and find it in the future

 

I must be missing something. I also have this problem. I try to open Monodevelop, it tells me "Unhandled exception", and then closes the program. So...

This doesn't work for me, because monodevelop won't even boot that far. How are you guys able access "Tools/Add-in Manager" at all?

 

I am having the same problem as Dubious Drewski. When I open a C# script in Unity, MonoDevelop immediately gives the following error message. I am not able to access any options.

Unhandled Exception. MonoDevelop will now close.

Is there probably a possibility to access Tools/Add-in-Manager manually without opening MonoDevelop?

I hope someone can help me

 

I half-fixed the problem.

I reinstalled Monodevelop. This required me to install something called GTK# for .NET 2.12.20 (Was that always a requirement?)

Anyway, Monodevelop runs now, but every hour or so, the whole interface glitches up and I have to restart. Sometimes it's a plain old CTD. It's really unstable, and I don't know what's going on. Before this mystery-change that started this all, Monodevelop used to run fine.

It's very upsetting.

 

In my case, I fixed my very similar error by garbage collecting my git. I didn't touch MonoDevelop although it is certainlly a bug there as well.
