So, my basic app has a small portion of code, though when removing all code the problem seems to persist. When reducing my application to the bare minimum, including the base **unoproj** template for the uno project and only `<App></App>`, the same problem arises. The exact error I’m getting from the console is:

```auto
Fuse 0.36.1 (build 12010)
Build started: FullCompile
Configuring
C:\Users\Jeklin\Desktop\jekoliyapp\app\jekoliyapp.unoproj: E0000: Object referen
ce not set to an instance of an object.
C:\Users\Jeklin\Desktop\jekoliyapp\app\jekoliyapp.unoproj(1,1): Error E0000: Obj
ect reference not set to an instance of an object.

Build completed in 1.19 seconds
    1 error
Build ended
fuse: Failed to compile project
Press any key to exit.

```

Which seems to be a C# issue. Though this error wasn’t happening the last time I booted fuse and tried to compile the app. Thanks for any replies 🙂

Hi Jack,

I suggest to try the following:

- Run `uno clean` inside the project folder
- If that does not fix it, please share your `unoproj` file.

Cheers!

Thank you friend! I tried executing `uno clean` on my project thou resulted in the same error, to continue - here’s my `unoproj` file:

**jekoliyapp.unoproj**

```auto
{
  "RootNamespace":"",
  "Packages": [
    "Fuse",
    "FuseJS"
  ],
  "Includes": [
    "*"
  ]
}

```

Right, the issue was I was using a folder in my root for the app called /Classes which for some reason when I moved it out, perfect compile!
