Try this,this will solve your problem:

Edit the applicationHost.config file found in %windir%\system32\inetsrv\config\ specifically the ApplicationPools section.

Change the IdentityType to NetworkService to use newly created database.

<pre><code>&lt;add name="ASP.NET v4.0" managedRuntimeVersion="v4.0"&gt;
 &lt;processModel identityType="NetworkService" loadUserProfile="true" setProfileEnvironment="true" /&gt;
&lt;/add&gt;
</code></pre>

Make sure that the application pool uses an identity that has access to the desired instance of the LocalDB. 

Then disable ASP.NET Impersonation in Authentication settings of the application. Otherwise, application uses <code>IUSR_MachineName</code> account to access the database. 

This setup may not be suitable for production environment but could be sufficient for database and application development.

blocks|key|2961282|text|我也有同样的问题，但有一个解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2961283|转到IIS服务器，然后转到从中运行应用程序的应用程序池。在应用程序池的高级设置中，有一个"Process+Model“选项，在该选项下有一个"Identity”选项。默认情况下，这是应用程序池标识。将其更改为Local+System，您就完成了。|2961284|并记住将其App_Data文件夹放在IIS服务器的WWW文件夹中|offset|length|style|BOLD|2961285|entityMap^0|0|0|0|O|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]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

I was also suffering from same problem, but there is a solution for it.

Go to the IIS server, and then to the application pool from which your application is running. In the advanced settings of the application pool there is a "Process Model" option, under which there is an "Identity" option. This is by default the application pool identity. Change it to Local System, and you're done.

And Remember to Put App_Data Folder their in WWW folder of IIS server

blocks|key|157252|text|也许这会对某人有帮助。我在安装一个空的Epise3rver+7.5%2B版本时也遇到了同样的问题，但很明显，这与任何设置或配置都没有关系，因为我的同事没有这个问题。我结束了卸载所有与MsSQL相关的应用程序，并重新安装了MSSQLExpress2014。它成功了！我之前试过安装2014，但它没有改变任何东西，所以我说我卸载了所有与MsSQL相关的东西，然后再安装2014。希望能有所帮助。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|157253|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|$]]

Maybe this will help someone. I had the same problem installing an empty Epise3rver 7.5+ version but it was clear it did not have to do with any settings or configurations since my colleagues did not have this problem. I ended uninstalling all MSSQL-related applications and reinstalled MsSQL Express 2014. And it worked! I tried before to install 2014 but it didn't change anything so as said I then uninstalled everything MsSQL-related before installing 2014 again. Hope it helps.

Using MVC 5.2.3.0 I had a similar issue...added this to my web.config.

<pre><code>&lt;!-- Configure the Sql Membership Provider --&gt; 
&lt;membership defaultProvider="SqlMembershipProvider" userIsOnlineTimeWindow="15"&gt; 
 &lt;providers&gt; 
 &lt;clear /&gt;

When I try to run my ASP.NET MVC 4 application using Local IIS on Windows 7 with Visual Studio 2013. I run into the following error when the application tries to connect to localDB\v11.0

<blockquote>
 Server Error in '/' Application.
 
 A network-related or instance-specific error occurred while
 establishing a connection to SQL Server. The server was not
 found or was not accessible. Verify that the instance name is correct
 and that SQL Server is configured to allow remote connections.
 (provider: SQL Network Interfaces, error: 50 - Local Database Runtime
 error occurred. Cannot create an automatic instance. See the Windows
 Application event log for error details. )
 
 The 2 event logs are
 
 Unexpected error occurred while trying to access the LocalDB instance
 registry configuration. See the Windows Application event log for
 error details.
 
 and
 
 Cannot get a local application data path. Most probably a user profile
 is not loaded. If LocalDB is executed under IIS, make sure that
 profile loading is enabled for the current user.
</blockquote>

Most solutions I found online references this post: <a href="http://blogs.msdn.com/b/sqlexpress/archive/2011/12/09/using-localdb-with-full-iis-part-1-user-profile.aspx">http://blogs.msdn.com/b/sqlexpress/archive/2011/12/09/using-localdb-with-full-iis-part-1-user-profile.aspx</a>

The only difference I see between the described situation and my situation is that the described error code is 0 whereas my error code is 50. However, the proposed solution does not work for me.

I cannot get past this error even if I set modify setProfileEnvironment to true and I've spent hours of time playing around with different processModel parameters and application pools.
