What's your connection string in the appsettings file ?
appsettings文件中的连接字符串是什么?
"DefaultConnection": "server=servername; database=EmployeeDB; User Id=sa; Password=xxx; Trusted_Connection=True; MultipleActiveResultSets=True;"
“DefaultConnection”:“server=servername;database=EmployeeDB;用户Id=sa;密码=xxx;Trusted_Connection=True;MultipleActiveResultSets=True;”
Do you have Microsoft.EntityFrameworkCore.SqlServer
package installed ? And what the packages do you installed ? Do you have another .json file where the connection string was messed up ?
是否已安装Microsoft.EntityFrameworkCore.SQL Server包?你安装了哪些软件包?你有没有另一个.json文件,连接字符串被搞砸了?
Yes, i have installed below packages Microsoft.EntityFrameworkCore.SqlServer and Microsoft.EntityFrameworkCore.Tools
是的,我已经安装了以下软件包Microsoft.EntityFrameworkCore.SQL Server和Microsoft.EntityFrameworks Core.Tools

The error message you're encountering, "Keyword not supported: 'server'", typically indicates an issue with your connection string in ASP.NET Core 6.0 when using Entity Framework Core for database operations. This issue is often related to a malformed connection string or a configuration problem. Here are the steps to troubleshoot and resolve this issue:
您遇到的错误消息“不支持关键字:'server'”通常表示在使用Entity Framework Core进行数据库操作时,ASP.NET Core 6.0中的连接字符串出现问题。此问题通常与格式错误的连接字符串或配置问题有关。以下是故障排除和解决此问题的步骤:
Check Your Connection String:
Ensure that your connection string in the appsettings.json
(or appsettings.Development.json
for development) file is correctly formatted. It should look something like this:
"ConnectionStrings": {
"DefaultConnection": "Server=YourServerName;Database=YourDatabaseName;User Id=YourUserId;Password=YourPassword;"
}
Make sure there are no extra quotes or syntax errors in the connection string. Replace "YourServerName," "YourDatabaseName," "YourUserId," and "YourPassword" with your actual database server details.
Verify DbContext Configuration:
In your ASP.NET Core project, make sure that your DbContext
class is properly configured with the connection string. It should be something like this in your Startup.cs
:
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
Ensure that you are using UseSqlServer
for SQL Server databases.
Entity Framework Core Migrations:
If you are using Entity Framework Core for database migrations, make sure you have run the following commands in the Package Manager Console or terminal to create and apply migrations:
dotnet ef migrations add InitialCreate
dotnet ef database update
Replace "InitialCreate" with an appropriate migration name.
Check for Special Characters:
Ensure that you don't have any special characters or escape sequences in your connection string that could be causing issues.
Test Connection String:
You can also test your connection string outside of your application to see if it's working correctly. You can use tools like SQL Server Management Studio or SQL Server Data Tools to test the connection.
Double-check Database Server:
Verify that your SQL Server instance is running and accessible from your application. Also, check if the server name is correct and that it allows connections from your application's server.
Review Entity Framework Core Version:
Ensure that you are using the correct version of Entity Framework Core that is compatible with ASP.NET Core 6.0.
Clear and Rebuild:
Sometimes, cached configurations can cause issues. Try clearing the bin and obj folders of your project, and then rebuild and run the application again.
After going through these steps, you should be able to identify and resolve the issue with your connection string and the "Keyword not supported: 'server'" error. If the problem persists, please provide more details about your connection string and configuration so that I can assist you further.
完成这些步骤后,您应该能够识别并解决连接字符串和“不支持关键字:'server'”错误的问题。如果问题仍然存在,请提供有关连接字符串和配置的更多详细信息,以便我可以进一步帮助您。
