C# Statement shows no results but results contain 3 values; why?

Hello -

I am new to LINQPad and just purchased my upgraded license. I went to run the following statement and it returns no results.

EPDMReferenceToolLicenseManagements.Where(epdmrtlm => epdmrtlm.DataField_Company == "Trident");

I know there is data in there that equals that value so I updated the code to be:

var res = EPDMReferenceToolLicenseManagements.Where(epdmrtlm => epdmrtlm.DataField_Company == "Trident"); Console.Write(res.Count());

The result is a value of 3, which is correct. Why does the data not show after the first statement? What am I missing?

MSTest with TestRunner inside LinqPad - Unresolved references in LinqPad.dll for a query

Hello there,

My goal is to run MsTests in LinqPad the same way I can NUnit inspired by this blog post( http://simoneb.github.io/blog/2012/10/28/nunit-via-linqpad/)

I have found this https://github.com/macro187/testrunner for running the tests via the console.

I managed to get it that far:

void Main()
{
// if is in the same process!
var testAsssembly = Assembly.GetExecutingAssembly().Location.Dump();

var testRunner = typeof(TestRunner.Program.TestResult).Assembly.Location.Dump();

Util.Cmd(testRunner, testAsssembly);
}


[TestClass]
public class Tests
{
[TestMethod]
public static void AlwaysTrue()
{
Assert.IsTrue(true);
}
}

with references added via NuGET:
MsTest.TestFramework, TestRunner

The error I get is :
"An internal error occurred in TestRunner.exe:
Could not load file or assembly 'Microsoft.VisualStudio.TestPlatform.TestFramework, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
Type: System.IO.FileNotFoundException"

Out of curiosity I decompiled just the LinqPad.dll for the query in ILSpy (standalone) and found the same "unresolved" reference.

I would appreciate any help.

NuGet window "show assemblies in package" is missing a file.

I have two machines on my office desk. Both running LINQPad.

I am accessing the same internal nuget server. Only difference is that I added the Nuget server through the LINQPad GUI on machine A, and copied the LINQPad settings file onto machine B.

When query was copied and pulled up inside LINQPad on machine B, it retrieved the package, but the query doesn't compile. The package is a single dll and a single dll from a dependency.

In the "show assemblies in package" on both computers, machine B shows only the (indirect) dependency assembly (1 file) whereas machine A shows both assemblies (the actual assembly as well as the external dependency assembly).

I don't see any error messages. A colleague tried to add the dependency this morning and he sees both assemblies.

I tried removing the nuget server entry and adding it manually. Then re-adding the nuget package after clearing the cache. No effect.

No matter what I do, the nuget package assembly wont appear. I have inspected the cache and the assembly is downloaded. It is just not reflected in LINQPad.

Namespace issue with expression vs using DbContext?

the following query generates an error in LinqPad:
from a in DcProductionAreas let b = "24.00".ParseDouble() select b
InvalidOperationException: The ModelDefinedFunctionAttribute for method ParseDouble must have namespaceName set to 'CodeFirstNamespace'.

Yet I can do the same thing as C# statements
using (var db = new DbEnvoyEFLib.DbEnvoyContext()) { var result = from a in db.DcProductionAreas let b = "24.00".ParseDouble() select b; result.Dump(); }

Linqpad can't differentiate between x86 and AnyCPU version when launching

1. Launch Linqpad(AnyCpu)

2. From command line try to open a .linq script in the x86 version:
@C:\Program Files (x86)\LINQPad5\LINQPad.exe "C:\Dropbox\LinqpadShared\LINQPad Queries\TextManipulation\PowerText52.linq"

3. The file opens in the existing LinqPad(AnyCpu) instance. It seems to open in whatever instance was launched first.

This is a problem since Linqpad can't run scripts that reference x64 dlls from the x86 instance and vice-versa. So I have some scripts that need to open in one instance, and some that need to open in the other.

Poor LpRun startup performance for simple script

When I have LinqPad up and running new scripts I write compile and execute nearly instantaneously.

However, when running on the command line via LpRun there is quite a long delay even for a trival script (~3-4 seconds).

I'm thinking of working around this by creating an LpRun background process that listens for execution requests and executes them using Util.Run() to avoid the startup overhead.

However, I'm wondering whether others have experienced this performance issue and whether built-in approaches are available for working around this?

SSO Authentication Default Browser and Account

June 5, 2018, 9:00 am
$
0
0
Background
I have a script that authenticate me through my Azure. This is really a single sign on auth to acquire STS token where LINQPad would show a browser for me to login. See the code below.

Issue and Attempt
I think the issue might have bee with the embedded web view in Linqpad. It is always default to a certain account and there's no way to clear cookies on this web view.
I also think this somewhat has to do with Windows Authentication. Whenever I'm on my corporate network, it default the login to my corporate account. The web view seems to pick up my Windows Authentication, thus, use the corporate account as default. This makes me suspect that LinqPad is using IE as the web view.
Similarly, in PowerShell, I can run `Login-AzureRmAccount` command, it would authenticate through SSO to acquire STS token. If I'm on the corporate network, PowerShell will also default to my corporate account. However, when I get off corporate network, it no longer default to corporate account.

The Ask.
Is there a way to specify browser to use for the web view? Or, is there a way to clear the cookies in that web view (not that I think it'd help since it's defaulting to my corporate account)?

Code
This is my code to authenticate with Azure

var aadInstance = "https://login.windows.net/{0}";
var resourceId = "https://someresource.windows.net/";
var aadTenantId = "";
var aadLinqpadClientId = "";
var aadLinqpadClientRedirectUri = "";

// Authenticate with Azure AD
AuthenticationContext authenticationContext;
if (TokenCache != null)
authenticationContext = new AuthenticationContext(string.Format(aadInstance, aadTenantId), TokenCache);
else
authenticationContext = new AuthenticationContext(string.Format(aadInstance, aadTenantId));
var authenticationResult = authenticationContext.AcquireTokenAsync(resourceId, aadLinqpadClientId, new Uri(aadLinqpadClientRedirectUri), new PlatformParameters(PromptBehavior.Auto)).Result;

if (authenticationResult == null)
throw new InvalidOperationException("Failed to obtain token");

return authenticationResult;


Any help would be appreciate it. Thanks!

Hello,

I am successfully connecting to an Azure SQL instance every day and querying. I would like to leverage LinqPad Pro Edition (v5.31.00) for the same reason, but use an ObjectContext. However, I cannot connect to the Azure SQL no matter how I approach it with LinqPad. I am using SQL Azure as the Provider for the LINQ to SQL Connection, and Windows Auth (AD) for Log On details. I've tried using Advanced for a manually-specified connString, to no avail.

tcp:xxxxxxxx-sql.database.windows.net,1433

Is what I am doing possible yet in LinqPad?


Thank you,
