Request redirect to /Account/Login?ReturnUrl=%2f since the installation on server

I'm working with asp.net core 2.1, I launch the app on my local machine without any problem and I can debug it and open it on the browser but when I deploy it to the server I get the rediction error and I can't login.
Here is my web.config file :
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="autoFormsAuthentication" value="false" />
<add key="enableSimpleMembership" value="false" />
</appSettings>

</connectionStrings>
</configuration>
<!--ProjectGuid: 5d471955-9737-4896-a960-3eb7ede4494e-->
I tried all the solutions montioned but I get the same error !
EDIT :
When I make the authentification to "Windows authentication" the error doesn't appear and if I make it as "Anonymous authentication" the error still here.

It was an error on my connection string and then the migration didn't update changes automaticaly. I fixed my connection string on appsettings.production.json and I updated the database.

For me, my IIS App pool runs under a specific account. When I had to re-create the database, I had to grant permissions to that account to the database.

Browser Link Visual Studio 2013 not working

I am new to VS 2013 and recently got introduced to a feature called Browser Link. I think it's an awesome feature provided by microsoft.
I am not able to get the connections.
Following steps I did
Created a new Empty MVC project
Created a controller Home and Action Index
Created a view Index.cshtml.
Solution was in debug mode.
Ran the solution.
Following is the web.config settings for the project

How to Configure UrlRewritingNet on asp.net web application client end

Please am fairly new to programming in asp.net and now am following the steps in a textbook to design an e-commerce web application.
I am using UrlRewritingNet dll from http://www.urlrewriting.net/ to create search engine friendly urls on the application. I unzipped the urlrewritingnet zip and copied its dll file to my application's bin folder. I also copied its urlrewritingnet.xsd file to my project folder. The textbook am working from uses the dll from urlrewriter.net with different configurations which I tried in my project but it didn't work. The textbook also uses visual web developer 2005. Am programming in visual studio 2012 (C#). For now am trying to rewrite the url of my catalogs page so as to test if the configuration in my web.config file is correct. I'm doing the configuration in my web.config, not in IIS. I do not want any IIS configurations because am imagining a scenario where I don't have access to the server.
I keep getting an internal server error that displays like this:
HTTP Error 500.22 - Internal Server Error
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.
this is the url which I want to rewrite: http://localhost:1036/Catalog.aspx?DepartmentID=1
This is my config file:
<configuration>
<configSections>
<section name="urlrewritingnet"
restartOnExternalChanges="true"
requirePermission ="false"
type="UrlRewritingNet.Configuration.UrlRewriteSection, UrlRewritingNet.UrlRewriter" />
</configSections>
<urlrewritingnet
rewriteOnlyVirtualUrls="true"

Difference between my local and production web.config

I get this error message
The connection string 'MyConnection' in the application's
configuration file does not contain the required providerName
attribute."
I read this question The connection string 'MyConnection' in the application's configuration file does not contain the required providerName attribute." about this same issue.
In my case the providerName="System.Data.SqlClient" is correctly in my web.config file in local but disappear when I do a publish on my production server (build in release). I don't have the problem on my local server.
EDIT
Here is my release config file
<?xml version="1.0" encoding="utf-8"?>
<!-- For more information on using web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=125889 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<!--
In the example below, the "SetAttributes" transform will change the value of
"connectionString" to use "ReleaseSQLServer" only when the "Match" locator
finds an attribute "name" that has a value of "MyDB".
<connectionStrings>
<add name="MyDB"
connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
-->
<system.web>
<compilation xdt:Transform="RemoveAttributes(debug)" />
<!--
In the example below, the "Replace" transform will replace the entire
<customErrors> section of your web.config file.
Note that because there is only one customErrors section under the
<system.web> node, there is no need to use the "xdt:Locator" attribute.
<customErrors defaultRedirect="GenericError.htm"
mode="RemoteOnly" xdt:Transform="Replace">
<error statusCode="500" redirect="InternalError.htm"/>
</customErrors>
-->
</system.web>
</configuration>

Use this for your release config file:
<connectionStrings>
<add name="MyDB"
connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)" providerName="System.Data.SqlClient" />
</connectionStrings>
ConnectionString for your local is being change by release config file. So if you declare providerName in your local config, that will be no use if you publish your release files. you need to declare the providerName in your release config file also.

Validation of viewstate MAC failed.Application hosted by a Web Farm, ensure <machineKey> configuration [duplicate]

This question already has answers here:
Asp.net Validation of viewstate MAC failed
(17 answers)
Closed 9 years ago.
net 4.0 frame work,
I had made many website in this frame work but never get such error
"Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster."
I think so this error is caused because of use of cookies as only in this website i had made use of cookies.
Another one thing i used to get this error very rarely almost 2twice a week
I had read many solutions for this but very rarer for 4.0
solution readed such as putting
<machineKey validationKey="6628ECBFB40F6F852AB543C23C0B83C1679C5AAE35AD72FACF5B9F4FDB70AA1F648A1D5877CE1F9D69F08BAD919BFBAC0976D9119B8F32CFB80814E4E943F8EE" decryptionKey="42F45B378301126EB4CCBA16995304263754EF116E08A81003A936CC04B7537F" validation="SHA1" decryption="AES" />
in web config
OR Adding
<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode ="Never" />
in webconfig
But where should i add in my above web config
<?xml version="1.0"?>
<configuration>
<connectionStrings>
<add name="Conn" connectionString="Data Source=abc; Initial Catalog=alfadesi_trikon;User ID=abc;Password=abc" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<globalization culture="en-AU" uiCulture="en-AU" />
<compilation debug="true" targetFramework="4.0"/>
<authentication mode="Windows"/>
<customErrors mode="Off"></customErrors>
</system.web>
</configuration>

you can add your machine key in system.web element.
for e.g.
<system.web>
<machineKey validationKey="1234567890123456789012345678901234567890AAAAAAAAAA"
decryptionKey="123456789012345678901234567890123456789012345678"
validation="SHA1" decryption="Auto" />
</system.web>
If you don't want to put a machinekey in the web.config for each application, you need to put it in machine level web.config for each .Net Framework version.
