I create a new C# project. I press play, the build fails with 1 error. This does not happen on another machine I use. I tried: Installing .NET 6 SDK, as well as 7. Installing Mono. Installing .NET Core 3. Restarting. Creating another project. Reinstalling the engine. Why is it even looking for this?: Unable to find fallback package folder 'C:\Users\Max\AppData\Roaming\Godot\mono\GodotNuGetFallbackFolder' Any help would be appreciated. Here is the full error text: Running ' dotnet build -c Debug --no-restore C:/Users/Max/Desktop/Unigine/unigine_project/unigine_project.csproj ' command MSBuild version 17.7.1+971bf70db for .NET C:\Program Files\dotnet\sdk\7.0.400\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(266,5): error MSB4018: The "ResolvePackageAssets" task failed unexpectedly.

Hello, ladies and gentlemen! Good news for every human being living in a managed world. Description A simple wrapper (source code included) which shows how to integrate Unigine with .NET and create apps (both WinForms and WPF). You have to have Unigine SDK if you want to use this sample. Build Instructions Extract contents of dot_net_sample.zip to <SDK> directory. Final path should be: <SDK>/source/samples/App/DotNet1. Make sure that $(UNIGINE_DIR) system variable set to Unigine 2.0 Alpha preview installation directory. Open Unigine.NET.sln in VS2012/VS2013; Select build configuration (Debug/Debug Double/Release/Release Double) and platform (x86/x64) according to your needs; Build Solution (F7); Copy <SDK>/source/samples/App/DotNet/unigine.cfg inside <built solution dir>/bin folder; Run built applications (AppWinForms.exe or AppWPF.exe); Have fun! Note: if you want to use float binaries from the sim sdk, you have to copy them inside <sdk_root>/lib folder in order to compile sample properly. You can find this sample in the attachments. Feel free to ask any questions! dot_net_sample.zip
