问题描述
我想我必须缺少一些明显的东西，但是我试图创建一个新的DesignAutomationClient对象，如下所示：
private void runDAButton_Click(object sender,EventArgs e)
{
createWorkItem();
}
private async Task createWorkItem()
{
var forgeConfig = new Autodesk.Forge.Core.ForgeConfiguration();
forgeConfig.ClientId = clientID;
forgeConfig.ClientSecret = clientSecret;
var apiInstance = new DesignAutomationClient();
// Code to create work item will go here
}
但是，当我这样做时，在尝试执行var apiInstance = new DesignAutomationClient();行之后，Visual Studio调试/立即窗口中出现以下错误：
抛出异常：mscorlib.dll中的'System.TypeLoadException'
我缺少明显的东西吗？设计自动化客户端是使用NuGet下载的，因此我应该具有所有必需的依赖关系，但是在论坛中搜索此类错误都表示这意味着我丢失了DLL文件，或者我正在寻找的类型没有存在于DLL中，我认为都不是真的。
此代码在用C＃编写的简单Windows窗体应用程序中 不涉及Web服务器或ASP.NET。 用户单击运行runDAButton_Click函数（依次运行createWorkItem（）函数）的窗体上的按钮。该函数应该创建API的实例，然后使用它来创建我的工作项。
有人可以帮忙吗？
解决方法
我们需要更多信息来进行故障排除，这是ASP .NET核心吗？您如何处理DI 但是，如果您的应用是.NET核心控制台应用，请从显示的代码中获取。 正确的方法是。

将Forge Env添加到您的launchSettings.json
{
"profiles": {
"daconsole": {
"commandName": "Project","environmentVariables": {
"FORGE_CLIENT_SECRET": "","FORGE_CLIENT_ID": ""
}
}
}
}
要运行：
dotnet run --launch-profile daconsole
