In my case  I had generated DbContext from an existing database  I had my connection string set in appSettings json file  however  when I generated the class files by scaffolding the DbContext class it had incorrect connection string  So make sure your connection string is proper in appSettings json file as well as in DbContext file  This will solve your issue

This is probably related to your database connection string or something like that   I just solved this exception right now  What was happening is that I was using a connection string intended to be used when debugging in a different machine  the server    I commented the wrong connection string in Web config and uncommented the right one  Now I m back in business    this is something I forget to look at after sometime not working in a given solution

Possibly also check the sessionState tag in Web config   Believe it or not  some projects I ve worked on will set a connection string here as well   Setting this config to     lt sessionState mode  InProc    gt    Fixed this issue in my case after checking all other connection strings were correct

There may be some reasons like    Wrong SQL connection string  SQL Server in services is not running   Distributed Transaction Coordinator service is not running     First try to connect from SQL Server Management Studio to your Remote database  If it connects it means problem is at the code side or at Visual Studio side if you are using the one    Check the connectionstring  if the problem persists  check these two services    Distributed Transaction Coordinator service  SQL Server services    Go in services msc and search and start these two services    The above answer works for the Exception   Win32Exception  0x80004005   The network path was not found

On my end  the problem was an unsuccessful connection to the VPN  while working from home   And yeah  the connectionString was using a context from remote server  Which resulted in the following error   lt Error gt     lt Message gt An error has occurred  lt  Message gt     lt ExceptionMessage gt The network path was not found lt  ExceptionMessage gt     lt ExceptionType gt System ComponentModel Win32Exception lt  ExceptionType gt     lt StackTrace  gt   lt  Error gt

At The Beginning  I faced the same error but with a different scenario  I was having two connection strings  one for ado net  and the other was for the EntityFramework  Both connections where correct  The problem specifically was within the edmx file of the EF  where I changed the ProviderManifestToken  quot 2012 quot  to ProviderManifestToken  quot 2008 quot  therefore  the application worked fine after that

As others pointed out this could be more to do with the connectionstring config Make sure    user id and password are correct Data Source is pointing to correct one   for example if you are using SQL express it will be   SQLEXPRESS Database is pointing to correct name of database Hope that helps
