How to modify the default database connection string

1. Open the file /src/Senparc.Web/App_Data/Database/SenparcConfig.config file

2. Directly edit the connection string under the <ConnectionStringFull> node, for example:

    <ConnectionStringFull>
        <![CDATA[Server=.\;Database=NCF;User ID=sa;Pwd=sa;Trusted_Connection=True;integrated security=True;]]>
    </ConnectionStringFull>

Note:

1. No need to modify any other content, other settings will be used for other purposes in the future, designed as a "maze" for hackers.

2. After the official release, this connection string will be encrypted, and we will provide an encryption tool.

Modularization: How different modules pass data to each other

Reference link: https://element.eleme.cn/#/Reference link: https://colorlib.com/polygon/gentelella/icons.html The module itself is still composed of classes and methods.

Using the Developer/master branch version after 2021-03-28, executing generation after using the XncfBuilder module does not generate any content

Causes and solutions:

1. The code is not up to date: Please pull the latest code.

2. XNCF command not installed locally:

Open the command line tool and execute the following command:

dotnet new install Senparc.Xncf.XncfBuilder.Template

Note: CLI commands before .NET 7 runtime need to use --install:

dotnet new --install Senparc.Xncf.XncfBuilder.Template

After execution, you will see the following content

Generate the module according to the XncfBuilder module, and select the locally installed option in the following image

3. The CLI of .NET 7 has a bug in generating templates. Please wait for the official fix or use the CLI of .NET 6.0.
