JetBrains Rider run with watch

There is an answer on Rider forum: https://rider-support.jetbrains.com/hc/en-us/community/posts/360001346139-Simpler-integration-for-Microsoft-DotNet-Watcher-Tools

In short:

1. Open Run Configurations dialog
2. Add new "Before launch" configuration
3. Select "External tool"
4. Fill in "Tool settings" section (see the link above)

---

Edit

The external tool settings should be:

• Program: c:\program files\dotnet\dotnet.exe
• Arguments: watch run
• Working directory: <path to your project folder>

You can use the "Native Executable" option as a run configuration to make this happen. To do so:

1. Select Run -> Edit Configuration from the menu options

2. Click the + icon and select the "Native Executable" option from the list.

3. In the options that are displayed, provide the following...

   • Name: Watch (or whatever you prefer)
   • Exe path: /usr/local/share/dotnet/dotnet
   • Program Arguments: watch run
   • Working directory: [path to your project where .csproj file resides]

4. Click "OK" to apply/save the changes.

5. When ready, select Run -> Run... from the menu options. Select the "Watch" option.

You should see the terminal results build/run the app. If you change your controller file, you'll see the file change detected and the app rebuild.
