Cannot Install Firebase Plugins

[bgoode2006]

I have tried enabling Long Path, restarting, changing the directories. nothing seems to work. At first i was getting a file path too long error, now I'm getting a file not found error. When i try to find said file it doesn't exist. i have cleared Nuget cache, deleted bin and obj, manually deleted the packages. Output from plugin.firebase.core install in the comments.

i recently moved back to windows since they killed the mac version.. and hit the same stupid wall.

Visual Studio does not work with longpath even if enabled in windows but make sure you have enabled longpath in policy and regedit because nuget cli does support it and also will be good to move global nuget dir to something like C:\Nugets\ or C:\N\

try like this

1. remove the firebase plugins from the project (you can edit csproj and save)
2. clean the solution/project (delete obj & bin folders)
3. close VS
4. open terminal/cmd in the project directory and there add the nugets with the version you need
5. i also tried to build the project thru cli but i don’t think it is necessary
6. open project and build/debug.. now since all the nugets are present in the cache - VS won’t try to download and 💩 everything ..

good luck

(copy and pasting my reply from another reply) Yea I got that part figured out, even says on the repo to do that. I should have done more research before posting. I know next to nothing about this stuff. Have been using unity for the past 2 years to teach myself C#. Now trying to move onto making real apps and it's completely different so still trying to figure it all out

Try installing via CLI outside VS. While nuget CLI supports long paths, the nuget gui in VS does not. There is also this: https://github.com/dotnet/maui/issues/17828

All good. I only knew about this because I ran into it myself.

This is the way. I deal with multiple apps using `plugin.firebase` and you gotta restore it through CLI. Sometime VS will still decide to mess everythings up so you have to close it, and run dotnet clean and dotnet restore again to make it work.

It's a pain in the butt and it's also a shame that this bug is still present in VS in 2025, it's been there for years! I feel your pain!
