在这个问题上，当我的功能中没有EventReceiver时，项目会构建和部署，当我有了EventReceivers时，项目就会失败。我不完全确定FileNotFoundException指的是哪个文件
visual studio 中出现错误

帮助
这对我很有用，
First resolution:
· Retract the Solution/WSP in VS.
· Close VS.
· Reopen VS and deploy the Project.
Second resolution:
If closing VS after retraction doesn't solve the problem then a larger workaround is:
· Redeploy the project -> This will show an error during feature activation.
· Go to SharePoint UI and Activate and then Deactivate the deployed feature that was showing activation error in VS.
· Retract the Solution/WSP in VS.
· Close VS.
· Reopen VS and deploy the Project.

这对我有效。
在项目上单击鼠标右键，然后选择属性。在"属性"菜单中，选择"签名"。在"签名"选项卡中，在"选择强名称密钥文件"下，选择"新建"并键入密钥名称。然后选择不需要密码。完成所有操作后，重新生成文件，然后就可以开始部署了。
这对我很有效：在程序集信息中更改VS项目的版本。例如，我将程序集和文件版本更改为1.1.0.0，而不是1.0.0.0。
已部署，没有问题。
之后，我可以将其设置回1.0.0.0，然后继续部署，不会出现错误或问题。。。
另一个帮助我的解决方案：转到要部署到的站点，然后从UI激活功能。从Visual Studio重新部署。
