-## Flax plugin for Visual Studio
-
-Flax Visual Studio extension provides better programming workflow, C# scripts debugging functionality and allows to attach to running engine instance to debug C# source. This extension is available to download [here](https://marketplace.visualstudio.com/items?itemName=Flax.FlaxVS).
-
 ## Windows
 
-* Install Visual Studio 2015 or newer
+* Install Visual Studio 2022 or newer
 * Install Windows 8.1 SDK or newer (via Visual Studio Installer)
 * Install Microsoft Visual C++ 2015 v140 toolset or newer (via Visual Studio Installer)
-* Install .Net Framework 4.5.2 SDK/Targeting Pack (via Visual Studio Installer)
+* Install .NET 7 SDK for **Windows x64** (via Visual Studio Installer or [from web](https://dotnet.microsoft.com/en-us/download/dotnet/7.0))
 * Install Git with LFS
 * Clone repo (with LFS)
 * Run **GenerateProjectFiles.bat**
 * Open `Flax.sln` and set solution configuration to **Editor.Development** and solution platform to **Win64**
 * Set Flax (C++) or FlaxEngine (C#) as startup project
 * Compile Flax project (hit F7 or CTRL+Shift+B)
+* Optionally set Debug Type to **Managed Only (.NET Core)** to debug C#-only, or **Mixed (.NET Core)** to debug both C++ and C#
 * Run Flax (hit F5 key)
 
-> When building on Windows to support Vulkan rendering, first install the Vulkan SDK then set an environment variable to provide the path to the SDK prior to running GenerateProjectFiles.bat: `set VULKAN_SDK=%sdk_path%`

 ## Linux
 
 * Install Visual Studio Code
-* Install Mono
-  * Ubuntu: see the instructions here: ([https://www.mono-project.com/download/stable](https://www.mono-project.com/download/stable))
-  * Arch: `sudo pacman -S mono`

 * Install XCode
-* Install Mono ([https://www.mono-project.com/download/stable](https://www.mono-project.com/download/stable))

 * Clone repo (with LFS)
 * Run `GenerateProjectFiles.command`
 * Open workspace with XCode or Visual Studio Code
 * Build and run (configuration  `Editor.Mac.Development`)
 
+#### Troubleshooting
+
+* `Could not execute because the specified command or file was not found.`
+
+Restart PC - ensure DotNet is added to PATH for command line tools execution.
+
+* `Microsoft.NET.TargetFrameworkInference.targets(141,5): error NETSDK1045: The current .NET SDK does not support targeting .NET 7.0.  Either target .NET 5.0 or lower, or use a version of the .NET SDK that supports .NET 7.0`
+
+Use Visual Studio 2022, older versions are not supported by .NET SDK 7.
+
+* `Building for Windows without Vulkan rendering backend (Vulkan SDK is missing)`
+
+Install the Vulkan SDK then set an environment variable to provide the path to the SDK prior to running GenerateProjectFiles.bat: `set VULKAN_SDK=%sdk_path%`.
+
+* `The NuGetSdkResolver did not resolve this SDK`
+
+Install `.NET SDK`, `NuGet package manager` and `NuGet targets and build tasks` in Visual Studio components.
