启动应用程序时发生错误，一旦我 运行 我的 ASP.NET IIS 核心项目

Question

我想发布一个 ASP.NET Core 3.1 应用程序到 IIS。

我遇到了一些问题。我添加了 dotnet-hosting-3.1.3-win 并将 applicationPool 更改为“无托管代码”。

发布文件夹中我的 web.config 看起来像这样

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <location path="." inheritInChildApplications="false">
        <system.webServer>
            <handlers>
                <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
            </handlers>
            <aspNetCore processPath="dotnet" 
                        arguments=".\Mehmanpazir.dll" 
                        stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" 
                        hostingModel="OutOfProcess" />
        </system.webServer>
    </location>
</configuration>
<!--ProjectGuid: 9df390e8-96df-4f6c-bc6b-f5fc9306940e-->

最终还是没能解决这个问题

An error occurred while starting the application.

我的日志是：

我找到了解决问题的方法。 我在连接字符串中使用了 windows 身份验证，发行者无法连接到我的 database.After 更改连接以连接用户名和密码，一切正常。
