blocks|key|4499839|text|经过一些研究，我能够安装VS+2015社区并使用它。在我的例子中发生了这种情况，因为我暂停了安装，并在稍后重新启动。我从我的电脑上卸载了VS2015，重启了我的电脑，并重新运行了安装程序(包括下载)，它工作了。回答我自己的问题，以防有人还在寻找解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4499840|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

After some research, I was able to install VS 2015 Community and use it. This happened in my case because I paused the installation and restarted it later on. I uninstalled VS 2015 from my computer, restarted my computer and re-ran the setup ( including downloads) and it worked. Answering my own question just in case anyone is still searching for solution.

blocks|key|4498893|text|以管理员身份运行devenv.exe。这对我很管用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4498894|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Run devenv.exe as administrator. It worked for me.

blocks|key|4499887|text|我也有这个问题，通常是因为在git+repo中包含了一个文件，而不是使用.gitignore。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4499888|我所做的就是进入项目目录...|4499889|/.vs/config/applicationhost.config|4499890|并删除了上面的文件，从那时起它就起作用了。我认为这是与UUID或类似的冲突。(总猜测)|4499891|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

I too had this issue, generally it came from including a file in a git repo instead of using .gitignore

What I did is went to the project directory...

/.vs/config/applicationhost.config

And deleted the above file, it worked from that point on. I believe it is a conflict with UUID's or some such. (total guess)

blocks|key|4498959|text|这个方法对我很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4498960|删除这两个文件夹的内容|4498961|C:\Users\%25USERNAME%25\AppData\Roaming\Microsoft\VisualStudio\
C:\Users\%25USERNAME%25\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache|code-block|syntax|javascript|4498962|然后以管理员身份运行VS.NET，否则它将无法正确续订Roaming文件夹。|offset|length|style|CODE|4498963|entityMap^0|0|0|0|R|7|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@$K|U|L|V|M|N]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

This method worked for me:

Delete contents of these 2 folders

<pre><code>C:\Users\%USERNAME%\AppData\Roaming\Microsoft\VisualStudio\
C:\Users\%USERNAME%\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache
</code></pre>

Then run the VS.NET as admin, otherwise it won't be able to renew the <code>Roaming</code> folder correctly.

blocks|key|4498995|text|在我的例子中，这是因为.csproj被配置为使用本地IIS。我对IIS做了一些更改，网站已经不在那里了。“输出”窗口中出现警告。编辑.csproj文件以指向新站点或重新创建站点将解决此问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4498996|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In my case it was because the .csproj was configured to use local IIS. I had made some changes to IIS and the website was no longer there. There was a warning in the output window. Editing the .csproj file to point to a new site, or re-creating the site will fix the issue.

blocks|key|4499934|text|对于我来说，删除整个项目目录，从Git重新克隆项目并重新启动Visual+Studio+(Community+2015)起作用了。在VS中打开重新克隆的项目时，系统会询问“该项目已配置为使用此计算机上未安装的IIS+Web服务器。是否要将该项目转换为使用IIS+Express?”|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4499935|在选择Yes时，VS将项目的web服务器设置为IIS+Express，并且项目加载和构建正常。|4499936|这最终将.csproj文件更改为UseIISExpress并设置IISUrl，这可能修复了“项目无法打开”的问题。|offset|length|style|CODE|4499937|entityMap^0|0|0|G|D|W|6|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@$F|O|G|P|H|I]|$F|Q|G|R|H|I]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|K|$]]

For me deleting the entire project directory, re-cloning the project from Git and restarting Visual Studio (Community 2015) worked. On opening the re-cloned project in VS, it asks "The project "" is configured to use IIS Web Server which is not installed on this computer. Would you like to convert the project to use IIS Express?" 

On opting Yes, VS sets the web server for the project to IIS Express and the project loads and builds fine.

This ends up changing the .csproj file to <code>UseIISExpress</code> and sets the <code>IISUrl</code>, which probably fixed the "Project could not be opened" issue.

blocks|key|4499052|text|安装Visual+Studio+2015更新3后也会发生此问题，可通过重新启动计算机来解决此问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4499053|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This also happens after installing Visual Studio 2015 update 3, solved by restarting the machine.

I am trying to install <a href="https://www.visualstudio.com/en-us/downloads/visual-studio-2015-downloads-vs" rel="noreferrer">Visual Studito 2015 RC</a> Community edition.

I downloaded the web installer and installed all components. After installation, I rebooted my machine as instructed, but it keeps giving me the same error when I try to make an application. Please see the screen below:

<img src="https://i.stack.imgur.com/YCwPX.jpg" alt="Screenshot showing the error &quot;Project ... could not be opened because the Visual C# 2015 RC compiler could not be created. Please re-install Visual Studio.&quot;">

I have tried <a href="https://stackoverflow.com/a/773787/1437261">this answer</a> and <a href="https://stackoverflow.com/a/13639375/1437261">this answer</a> from earlier versions of Visual Studio. It resets the settings but ultimately had the same error.

I have also tried removing <code>C:\Users\Gogol\AppData\Local\Microsoft\VisualStudio</code> folder, but again, no luck.

I also have <code>devenv.exe</code> added to the path. I can access <code>devenv</code> in command prompt.
