I am trying to make a simple insert into my sqlserver database using Dapper. This is my code:
using var db = DbContext.CreateConnection();
db.Open();
string sqlQuery =
"INSERT INTO Account (Id, Balance, NumberOfTransactions) VALUES(#Id, #Balance, #NumberOfTransactions)";
int rowsAffected = db.Execute(sqlQuery, entity);
return rowsAffected > 0;
And this is my DapperContext.
public DapperContext(IConfiguration configuration)
{
_configuration = configuration;
_connectionString = _configuration.GetConnectionString("DapperConnection");
}
public IDbConnection CreateConnection()
=> new SqlConnection(_connectionString);
But when I reach the Execute line I am getting Could not load file or assembly 'Microsoft.SqlServer.Server'. I have no idea why. My SQLServer is being hosted by a docker image. And I've already installed the Server nuget. Here's the list of nugets that I currently have installed:
<PackageReference Include="Akka" Version="1.4.39" />
<PackageReference Include="Akka.DependencyInjection" Version="1.4.39" />
<PackageReference Include="Akka.Remote" Version="1.4.39" />

<PackageReference Include="Microsoft.SqlServer.Types" Version="160.600.9-ctp2p0" />
<PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />
Anyone can help me what might be wrong here and why do I keep getting this could not load error? I even already download SQL Server from Microsoft but my idea was to use my docker container instead.
Stack trace:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.SqlServer.Server, Version=5.0.0.0, Culture=neutral, PublicKeyToken=23ec7fc2d6eaa4a5'. The system cannot find the file specified.
File name: 'Microsoft.SqlServer.Server, Version=5.0.0.0, Culture=neutral, PublicKeyToken=23ec7fc2d6eaa4a5'
I was using the wrong version of the nuget package. I had to replace PackageReference Include="Microsoft.Data.SqlClient" Version="5.0.0-preview3.22168.1 with PackageReference Include="System.Data.SqlClient" Version="4.8.3" and it worked right away

I just upgraded from EF 6 -> EF Core 7 in my ASP.NET Core 6 MVC app because I needed the context.Database.SqlQuery<T>() functionality; however, when I try to run any query via EF it now appears unable to connect at all when I build & run or execute migration cmds:
C:\Path\To\My\Project\Ui>dotnet ef database update --context sqliteascertodbcontext
Build started...
Build succeeded.
Debug: Registered integration with EF Core.
An error occurred using the connection to database 'main' on server 'C:\Path\To\My\Project\Ui\db.sqlite3'.

You need to bump Microsoft.AspNetCore.TestHost to a compatible 3.x version (PR submitted).
TL:DR -- How do I add System.Web.Ui.WebControls to my AdhocWorkspace?
Long version...
My unit test for an analyzer is failing because the test compilation environment doesn't have a reference to System.Web.Ui.WebControls. I need to get a semantic type, and that is failing because it doesn't know what the type is.
My test project is core2.0:
<PropertyGroup>
<TargetFramework>netcoreapp2.0</TargetFramework>

My DiagnosticVerifier has:
private static readonly MetadataReference CorlibReference = MetadataReference.CreateFromFile(typeof(object).Assembly.Location);
private static readonly MetadataReference SystemCoreReference = MetadataReference.CreateFromFile(typeof(Enumerable).Assembly.Location);
private static readonly MetadataReference CSharpSymbolsReference = MetadataReference.CreateFromFile(typeof(CSharpCompilation).Assembly.Location);
private static readonly MetadataReference VBLangSymbolsReference = MetadataReference.CreateFromFile(typeof(VisualBasicCompilation).Assembly.Location);
private static readonly MetadataReference CodeAnalysisReference = MetadataReference.CreateFromFile(typeof(Compilation).Assembly.Location);
private static readonly MetadataReference SystemData = MetadataReference.CreateFromFile(typeof(System.Data.DataRow).Assembly.Location);
private static readonly MetadataReference SystemWeb = MetadataReference.CreateFromFile(typeof(System.Web.HttpUtility).Assembly.Location);
And adds them to the workspace via:
var solution = new AdhocWorkspace()
.CurrentSolution
.AddProject(projectId, TestProjectName, TestProjectName, language)
.AddMetadataReference(projectId, CorlibReference)
.AddMetadataReference(projectId, SystemCoreReference)
.AddMetadataReference(projectId, CSharpSymbolsReference)
.AddMetadataReference(projectId, VBLangSymbolsReference)
.AddMetadataReference(projectId, CodeAnalysisReference)
.AddMetadataReference(projectId, SystemData)
.AddMetadataReference(projectId, SystemWeb)
But I'm still getting a Type 'Label' not is not defined from context.Compilation.GetDiagnostics(), which prevents me from determining what the type of the label.Text.
I solved this by creating 2 new references obtained from the .net framework in the 'c:\program files (x86)\reference assemblies\microsoft\framework.netframework\v4.0\' directory and loading from the path.
So, I commented out
.AddMetadataReference(projectId, CorlibReference)
.AddMetadataReference(projectId, SystemCoreReference)
and added in
.AddMetadataReference(projectId, SystemCore)
.AddMetadataReference(projectId, SystemReference)
I also changed the SystemWeb reference to be gathered from the same directory. After that it worked.
I must be missing something but I cannot see it.
I have created a new 'empty' ASP.NET Core 2.0 Project
