ASP.NET Website Administration Tool (WSAT) common problems

Problem: Role Manager is Not Enabled

Solution: Open your web.config file and ensure the role manager is enabled.

Add or modify the following section:

<system.web>
  <authentication mode="Forms" />
  <roleManager enabled="true" />
</system.web>

Problem: ASP.NET Membership Database is Missing

Solution: Run the ASP.NET database setup tool to create the required membership tables:

Open Command Prompt and navigate to: cd C:\Windows\Microsoft.NET\Framework\v4.0.30319 Run: aspnet_regsql.exe Follow the wizard to configure the ASP.NET membership database.

Problem: The Database is Not Properly Configured in WSAT

Solution: In WSAT, click the "Choose a new data store" button and ensure it points to the correct database.

Problem: I have followed all of your advice. but it says the same problem , additionally it says "The following message may help in diagnosing the problem: Access to the path 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\appadmin\f11ba3f2\4b28c3cb\hash' is denied."

Solution:

1. Grant Full Permissions to the Temporary ASP.NET Files Folder Navigate to the Folder Open File Explorer and go to: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files Right-click on the "Temporary ASP.NET Files" folder → Select Properties. Go to the Security tab → Click Edit → Click Add. Add the required users: Enter Everyone and click OK. Add IIS_IUSRS (for IIS applications). Add NETWORK SERVICE (if your app runs under Network Service). Add Users and Authenticated Users. Give "Full Control" to these users and click OK.

2️. Clear the Temporary ASP.NET Files Close Visual Studio or any running ASP.NET applications. Manually delete all files from: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files and C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files Restart your computer or restart IIS by running: iisreset in Command Prompt (Run as Administrator).

3️. Run Visual Studio as Administrator Right-click on Visual Studio and select Run as administrator. Then try launching the ASP.NET Website Administration Tool (WSAT) again.

4️. Ensure Your Application Pool Has Correct Identity Open IIS Manager (inetmgr). Go to Application Pools. Find your App Pool and check its Identity (e.g., ApplicationPoolIdentity, NetworkService). Ensure that identity has read/write permissions to C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files.

For code first migration

1. If you use this line in Global.asax.cs file in application_start method:

System.Data.Entity.Database.SetInitializer(new DropCreateDatabaseIfModelChanges<MvcMusicStore.Models.MusicStoreEntities>());
or System.Data.Entity.Database.SetInitializer(new MvcMusicStore.Models.SampleData());

then you don't need to execute the command like: Enable-Migrations, Add-Migration InitialCreate, Update-Database.

2. But if you don't want that and comment out that line of code, then first delete your existing database then you have to exceute in Package Manager Console:Enable-Migrations, Add-Migration InitialCreate, Update-Database.
3. But

• If you have data in your database and Initial_Migration file in Migration folder then you don't need to delete it and then you have to execute in Package Manager Console:Enable-Migrations, Update-Database. you can use -Force if you want to create database forcefully.
• if in your Configuration class, constructor has this line, then you don't need to excute : Enable-Migrations, Just Add-Migration InitialCreate, Update-Database.

public Configuration()
    {
        AutomaticMigrationsEnabled = true;  // Enables automatic migrations
        AutomaticMigrationDataLossAllowed = false; // Prevents accidental data loss
    }

• If you have a Migration folder with an Initial_Create file, then just Update-Database will work. So, for this project code, only Update-Database will work.

4. After verification if your database has _MigrationHistory table, then for the new changes you can use Add-Migration NewChanges(any name) and Update-Database. use Update-Database -Script to see the script before applying it to the database. or Update-Database -Force to recreate the database.
5. Finally you fill out the seed method in Configuration class. Then you can get your filled data in the database as well.
