Short practical options to avoid rebuilding the database on every machine (followups to and ).

One-time script or backup/restore: use SQL Server Management Studio’s Generate Scripts wizard to create a schema+data script (use the Advanced options — “Types of data to script”, “Include if NOT EXISTS”, etc.) or create a full .bak and restore it on the target machine with T-SQL. This is the safest when you must reproduce an exact schema and data set on other PCs. (learn.microsoft.com)

Ship a file-based database (LocalDB / AttachDbFilename): include the .mdf in your installer or project, set it to copy to the output folder, and use an AttachDbFilename connection so the app attaches the file at runtime. Use the |DataDirectory| substitution so paths stay relative, and prefer LocalDB on target PCs because it’s a lightweight SQL Express runtime that supports AttachDbFilename. Note: LocalDB can detach the database when the app closes if the Database name is not specified — test the behavior you need. Example connection string and setting DataDirectory in VB.NET:

AppDomain.CurrentDomain.SetData("DataDirectory", Application.StartupPath)
Dim cs = "Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\MyDB.mdf;Integrated Security=True;"

(learn.microsoft.com)

Package + automate: create a .dacpac/.bacpac (or use sqlpackage.exe) to export schema+data and import on the target, or bundle a .sql deploy script and run it during install/startup. When executing a .sql file from code, split the file on the GO batch separator (GO is a client-side batch marker — not valid T-SQL for SqlCommand) before sending batches to SqlCommand. Example VB.NET snippet to run a .sql file:

Dim sql = File.ReadAllText("deploy.sql")
Dim batches = Regex.Split(sql, "^\s*GO\s*$", RegexOptions.Multiline Or RegexOptions.IgnoreCase)
Using cn As New SqlConnection(cs)
  cn.Open()
  For Each b In batches
    If b.Trim() <> "" Then New SqlCommand(b, cn).ExecuteNonQuery()
  Next
End Using

(learn.microsoft.com)

Pick based on constraints: for quick lab deployment use LocalDB + shipped .mdf; for controlled reproducible installs use .bak or .dacpac; for shared data use a central hosted SQL instance. Also ensure the target machine has the appropriate SQL runtime and required permissions before deploying.

The solution that comes to mind immediately is to host the database on an internet accessible machine, and set your Data Connection accordingly. Another possibility is to script the database objects and run that script on each new machine (you would also have to run it again when you alter the database objects).

Assuming Visual Studio, Click View...Server Explorer
Right-Click the server, select publish to provider
Walk through the dialogs

Did you try to google "script database visual studio" yet?
