سلام من یک برنامه نوشتم که اطلاعات کاربر (نام ، نام خانوادگی و شماره) رو در دیتابیس ذخیره میکنه
خب این تا وقتی هست که من توی رایانه خودم هستم کار میکنه !
با استفاده از کلاس LINQ یا همون LINQ to SQL Classes با این بانک ارتباط برقرار کردم
بعد رفتم یک Accountـه جدید در کامپیوترم ساختم و برنامه + خودِ دیتابیس رو توی یک پوشه توی Accountـه جدید کپی کردم ، اومدم برنامه رو باز کنم اما با این ارور مواجه شدم
حتی من app.config رو ادیت کردم
از
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="testing.Properties.Settings.testingConnectionString"
connectionString="Data Source=(localdb)\Projects;Initial Catalog=test-db;Integrated Security=True"
providerName="System.Data.SqlClient" />
<add name="testing.Properties.Settings.testingConnectionString1"
connectionString="Data Source=|(localdb)\Projects;Initial Catalog=test-db;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
