    The cause: The MVC entity framework connection string contains incorrect meta data. Several entity models for several databases were used in the project. The connection strings, however, had been replicated to the other databases, and the database settings and credentials had been modified. But neglected to change the names of the entity models in the connectionstring’s meta data part.

    Solution: 

    Names of database models in connection strings should be updated to fix the error the entity type is not part of the model for the current context.

    The cause:

    You’ll probably run into this issue if you’re utilizing the connection string created while importing the EDMX file using in:base(“EDMXConnString”).

    Solution: By establishing a common connection string that referred to the database containing the ASP.NET Identity tables, you were able to resolve the error: the entity type applicationuser is not part of the model for the current context.

    <add name=MyConnString connectionString=Data Source=server; Initial Catalog=db_name; User ID=user_id; Password=password; Connect Timeout=60; providerName=System.Data.SqlClient />

    It then will work when you use the connection string in :base.

    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base(MyConnString)
{
}
}

    To ensure that a context instanciation is not missed, the code should be as follows:

    UserManagerFactory = () => new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));

    Solution: Solution 1. The issue refers to start rather than myfunction. Here, you wait for the myfunction to complete before returning a promise that will also be awaited.

    Solution:

    Solution 1.

    The issue refers to start rather than myfunction. Here, you wait for the myfunction to complete before returning a promise that will also be awaited. Point out that you may return the promise that myfunction returned instead of using the async hashtag on the function.

    async function myfunction() {
console.log('Inside of myfunction');
}

function start() {
return myfunction();
}

// Call start
(async() => {
console.log('before start');

await start();

console.log('after start');
})();

    Solution 2.

    This error message actually referred to the map function’s lack of a “async” designation. By removing the “await” call from the map function and finding another way to achieve the desired behavior, the syntaxerror: await is only valid in async function can be fixed.

    var myfunction = async function(x,y) {
....
someArray.map(someVariable => { // <- This was the function giving the error
return await someFunction(someVariable);
});
}

    The following was observed:
