dotnet watch not releasing .pdb file when restart is requested after a hot reload has occurred #45831
Open
Description
Describe the bug
When running a standalone WASM project via dotnet watch within Visual Studio (Developer PowerShell console), a request to restart that occurs after a hot reload will fail, due to the project's .pdb file being held.
This behavior was introduced when I updated to VS 17.12.3 from 17.11.
To Reproduce
- Open attached solution
WasmStandalonein VS. - Open Developer Powershell prompt.
- Run the attached project with
dotnet watch run --project .\WasmStandalone.csproj - Browser will launch to Home.razor.
- Make a change to some text in Home.razor.
- Observe dotnet watch handle the change and hot reload (5-10 seconds).
- Type
Ctl-Shift-Rin the Developer PowerShell console to request a restart - Observe error saying pdf file can't be opened for writing; "being used by another process"
Observed sequence:
Sample project:
WasmStandalone.zip
