- Trick: Run the project with Ctrl+Shift+B Change the .vscode/task.json by set task build's isBuildCommand as false, set task run's isBuildCommand as true, like:
{
"version": "0.1.0",
"command": "dotnet",
"isShellCommand": true,
"args": [],
"tasks": [
{
"taskName": "build",
"args": [
"${workspaceRoot}\\project.json"
],
"isBuildCommand": false,
"problemMatcher": "$msCompile"
},
{
"taskName": "run",
"args": [
"${workspaceRoot}\\project.json"
],
"isBuildCommand": true,
"problemMatcher": "$msCompile"
}
]
}- Try the trick Press Ctrl+Shift+B Output: Project NetApp (.NETCoreApp,Version=v1.0) was previously compiled. Skipping compilation. Hello World!
