Is there any suggestion for PostgreSQL to add type Nvarchar?
This is the error that I am getting:
Npgsql.PostgresException (0x80004005): 42704: type "nvarchar" does not exist

Thank you.
"National" string data types are a vestige from the dim and distant past when people still used single-byte encodings like ISO 8859-1 or Windows-1252.
Nowadays we store data using UNICODE encodings, in the case of PostgreSQL, UTF-8. Since you can store any character that way, there is no need for a special data type.
This error occured to me when my last migration (which the update-database command uses) was not for a PostgreSQL connection.
You can try this:
create a new migration with add-migration <name>
clear the database with update-database 0
apply the newly created migration on the database with update-database
In my case, first I was using SQL Server as DB and changed to PostgreSQL. Old migrations were caused the problem type "nvarchar" does not exist. Deleted old migrations and created new migration, updated everything worked fine.
I try to generate report RDLC, it is working okay with my Windows 10. But when I try to run on my MacOS 10.15.17. The errror below is showing. Please help check. I am thinking it is not supporting the .net framework on Macbook machine. Only Dotnet core supported. But I really need RDLC report. Because there is no better solution yet.

Handling *.aspx is not defined in iis. go into
IIS manager --> Default Website --> handler Mapping
Check if you have a mapping for aspx... ideally you should see 2 mappings for .aspx...
you can also use the command line to get the info by the following:
C:\Windows\System32\inetsrv>appcmd list config "Default Web Site" -section:handlers >"give output txt file name"
I am trying to load a certificate in a class that is hosted in IIS.
The code that i used is:
X509Certificate2 privateCertificate = new X509Certificate2(#"C:\Temp\file.pfx", "mycertpass");
Later on in my code when privateCertificate is used it causes a problem on the production environment. This problem does not occur on the local environment, the exception is as follows:

I thought it might be a permission on folder problem however i have added "everyone" with full access temporarily and this did not solve the problem either.
Any ideas would be appreciated.
Make sure C:\Temp\file.pfx path is accesible. probably you want to test Server.MapPath("~/folder/" + filename).
Also check out the identity of your app pool and make sure that the Load user profile option is turned on, otherwise the crypto susbsystem won't work.
Try specifying X509KeyStorageFlags
var certificate = new X509Certificate2(KeyFilePath, KeyFilePassword,
X509KeyStorageFlags.MachineKeySet |
X509KeyStorageFlags.PersistKeySet |
X509KeyStorageFlags.Exportable);
I'm using some 3rd party software that's failing. Their API is wrapped in a ASP web service.
The call stack tells me that it needs maybe MySQL.Data.DLL or something (not sure exactly) in the correct directory. So I'm wondering where that directory would be. The Web Server is IIS.
Here is the call stack:

I needed to copy MySQL.data.dll to the bin directory of my web service application directory. I also added the config key to the web.config.
