无法加载接收器程序集 - 文件未找到异常。

Question

处理这个问题时，当我的功能中没有事件接收器时，项目可以构建和部署，而添加事件接收器后则失败了。我并不完全确定FileNotFoundException指的是哪个文件。

Visual Studio中给出的错误信息：

Error   1   Error occurred in deployment step 'Activate Features': Failed to load receiver assembly "Decisions.Features, Version=1.0.0.0, Culture=neutral, PublicKeyToken=8d09acb153961cfd" for feature "Decisions.Features_DeployDecisionCommittee" (ID: 779492d8-f053-45ce-8340-5fa6d7f87a90).: System.IO.FileNotFoundException: Could not load file or assembly 'Decisions.Features, Version=1.0.0.0, Culture=neutral, PublicKeyToken=8d09acb153961cfd' or one of its dependencies.

Decisions.Features.DLL是您包含在软件包中的程序集吗？检查生成的.WSP文件，看看程序集是否实际包含在内（您可以使用7-zip轻松解压缩WSP文件并保持结构）。 - Tatjana N.

嗨，Colin，你找到解决方法了吗？ - Mathematics

Answer 1

这是我尝试过的有效方法：

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.

Answer 2

这对我有用。

右键单击项目并选择属性。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输入密钥名称。然后选择不需要密码。完成所有操作后重新构建文件，即可开始部署。

Answer 3

这对我有用：更改程序集信息中的VS项目版本。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。

部署后没有问题。

之后，我可以将其设置回1.0.0.0，并继续部署而没有错误或问题...

Answer 4

另一个帮助我的解决方案： 前往您要部署的站点，并从UI中激活功能。 从Visual Studio重新部署。
