- Pib Visual Studio 2017.
- Los ntawm cov ntawv qhia zaub mov, nyem Tshiab, tom qab ntawd nyem qhov Project (lossis nyem CTRL + Ua haujlwm + N).
- Xaiv SQL Server Database Project, thiab ntaus thiab nkag mus rau WideWorldImporters-SSDT ua lub npe project.
- Nyem OK los tsim qhov project.
Dab tsi yog dataset hauv Visual Studio?
A dataset yog ib txheej ntawm cov khoom uas khaws cov ntaub ntawv los ntawm cov ntaub ntawv hauv lub cim xeeb thiab txhawb kev hloov kev taug qab los pab tsim, nyeem, hloov kho, thiab tshem tawm (CRUD) cov haujlwm ntawm cov ntaub ntawv tsis tas yuav tsum txuas nrog cov ntaub ntawv ib txwm. Ua haujlwm nrog cov ntaub ntawv , koj yuav tsum muaj ib yooj yim paub txog cov ntsiab lus database.
