更多细节 ：

我在基于C＃的Windows Phone中创建的每种类型的项目中都存在错误（全景，databind应用，HTML5等）

我尝试过的

如果您要解决的问题包括重新安装，请不要打扰。 我已经尝试了太多次了。

更多信息

我新安装了带有Blend的Visual Studio 2012。 在安装时，我未选中Blend。 然后创建一个新的Windows Phone项目。 那花了4个小时下载了SDK（慢速网络..不相关），然后在完成后重新启动了计算机。 然后，我为Windows Phone创建了一个新项目。 并得到了相同的错误。 如果我缺少任何东西，请引导我。

已经为此向Microsoft报告了一个错误。 看这里 。

但是， re-installation did trick for most of them 。 确保按照此处报告的步骤操作，以重新安装VS2012。

如果有帮助，请尝试此步骤（ Source ）-

我也有这个问题。 我能够通过将<loadFromRemoteSources enabled="true"/>到xdesproc.exe.config（如Marco所述）和devenv.exe.config来修复它。 这两个文件都位于C：\\ Program Files（x86）\\ Microsoft Visual Studio 11.0 \\ Common7 \\ IDE中。
