From the [release notes](http://blog.nuget.org/20130814/nuget-2.7-release-candidate.html)

&gt;If we detect that any of your packages were affected by the retargeting or upgrade, we’ll produce immediate build errors to let you know. In addition to the immediate build error, we also persist a requireReinstallation=&quot;true&quot; flag in your packages.config file for all packages that were affected by the retargeting, and each subsequent build in Visual Studio will raise a build warnings for those packages.

Essentially, NuGeT is automatically flagging packages which conflict with your project target or version


I have a sample `sh` script on my Linux environment, which basically run&#39;s the `ssh-agent` for the current shell, adds a key to it and runs two git commands:

    #!/bin/bash
    eval &quot;$(ssh-agent -s)&quot;
    ssh-add /home/duvdevan/.ssh/id_rsa
    
    git -C /var/www/duvdevan/ reset --hard origin/master
    git -C /var/www/duvdevan/ pull origin master

Script actually works fine, but every time I run it I get a new process so I think it might become a performance issue and I might end up having useless processes out there.

An example of the output:

    Agent pid 12109
    Identity added: /home/duvdevan/.ssh/custom_rsa (rsa w/o comment)

Also, along with all this, is it possible to find an existing `ssh-agent` process and add my keys into it?

How to check if ssh-agent is already running in bash?

Dependencies decorated by `&lt;optional&gt;true&lt;/optional&gt;` or `&lt;scope&gt;provided&lt;/scope&gt;` will be ignored when they are dependent transitively. I have read [this][1], my understanding is like the difference between @Component and @Service in Spring, they only vary semantically.

Is it right?

I upgraded my C# project (which already had some nuget packages) from 4.0 to 4.5.2. I saw that some `&lt;package /&gt;` elements now contain an additional attribute `requireReinstallation=&quot;true&quot;`. 

* What is the purpose of this?

* Why is that some packages have while others don&#39;t.

I&#39;m going mad. I just want the culture used in the entire Asp.net core application to be set to &quot;en-US&quot;. But nothing seems to work. Where to I set the culture for the entire application? I&#39;m not interested in client browser cultures and what not. The only thing that seems to change it is changing the language settings of Windows. I just want the culture to be determined from within the application itself, not by the client.

What I have tried so far:

- Set `&lt;system.web&gt;&lt;globalization uiCulture=&quot;en&quot; culture=&quot;en-US&quot; /&gt;&lt;/system.web&gt;` in web.config
- Set `System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo;` and `CurrentUICulture` in Startup.Configure and even in the controller.
- Use `app.UseRequestLocalization(..` as shown below

            var enUsCulture = new CultureInfo(&quot;en-US&quot;);
            var localizationOptions = new RequestLocalizationOptions()
            {
                SupportedCultures = new List&lt;CultureInfo&gt;()
                {
                    enUsCulture
                },
                SupportedUICultures = new List&lt;CultureInfo&gt;()
                {
                    enUsCulture
                },
                DefaultRequestCulture = new RequestCulture(enUsCulture),
                FallBackToParentCultures = false,
                FallBackToParentUICultures = false,
                RequestCultureProviders = null
            };

            app.UseRequestLocalization(localizationOptions);

But nothing seems to change the CurrencyDecimalSeparator from (nl-NL) , to (en-US).

How can the culture be set?

**EDIT:**
@soren
This is how the configure method looks like. I&#39;ve put a breakpoint on `DetermineProviderCultureResult` but it is never hit while visiting the website.

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, FinOsDbContext context)

            };
            requestOpt.SupportedUICultures = new List&lt;CultureInfo&gt;
            {
                new CultureInfo(&quot;en-US&quot;)
            };
            requestOpt.RequestCultureProviders.Clear();
            requestOpt.RequestCultureProviders.Add(new SingleCultureProvider());

            app.UseRequestLocalization(requestOpt);

            FinOsDbContext.Initialize(context);
            FinOsDbContext.CreateTestData(context);
        }

        public class SingleCultureProvider : IRequestCultureProvider
        {
            public Task&lt;ProviderCultureResult&gt; DetermineProviderCultureResult(HttpContext httpContext)
            {
                return Task.Run(() =&gt; new ProviderCultureResult(&quot;en-US&quot;, &quot;en-US&quot;));
            }
        }

Set CultureInfo in Asp.net Core to have a . as CurrencyDecimalSeparator instead of ,

I&#39;m trying to create a unit test for a class that calls into an async repository.  I&#39;m using ASP.NET Core and Entity Framework Core.  My generic repository looks like this.

    public class EntityRepository&lt;TEntity&gt; : IEntityRepository&lt;TEntity&gt; where TEntity : class
    {
        private readonly SaasDispatcherDbContext _dbContext;
        private readonly DbSet&lt;TEntity&gt; _dbSet;

        public EntityRepository(SaasDispatcherDbContext dbContext)
        {
            _dbContext = dbContext;
            _dbSet = dbContext.Set&lt;TEntity&gt;();
        }

        public virtual IQueryable&lt;TEntity&gt; GetAll()
        {
            return _dbSet;
        }

        public virtual async Task&lt;TEntity&gt; FindByIdAsync(int id)
        {
            return await _dbSet.FindAsync(id);
        }

        public virtual IQueryable&lt;TEntity&gt; FindBy(Expression&lt;Func&lt;TEntity, bool&gt;&gt; predicate)
        {
            return _dbSet.Where(predicate);
        }

        public virtual void Add(TEntity entity)
        {
            _dbSet.Add(entity);
        }
        public virtual void Delete(TEntity entity)
        {
            _dbSet.Remove(entity);
        }

        public virtual void Update(TEntity entity)
        {
            _dbContext.Entry(entity).State = EntityState.Modified;
        }

        public virtual async Task SaveChangesAsync()
        {
            await _dbContext.SaveChangesAsync();
        }
    }
  
Then I have a service class that calls FindBy and FirstOrDefaultAsync on an instance of the repository:

        public async Task&lt;Uri&gt; GetCompanyProductURLAsync(Guid externalCompanyID, string productCode, Guid loginToken)
        {            
            CompanyProductUrl companyProductUrl = await _Repository.FindBy(u =&gt; u.Company.ExternalCompanyID == externalCompanyID &amp;&amp; u.Product.Code == productCode.Trim()).FirstOrDefaultAsync();

            if (companyProductUrl == null)
            {
                return null;
            }

            var builder = new UriBuilder(companyProductUrl.Url);
            builder.Query = $&quot;-s{loginToken.ToString()}&quot;;

            return builder.Uri;
        }

I&#39;m trying to mock the repository call in my test below:

        [Fact]
        public async Task GetCompanyProductURLAsync_ReturnsNullForInvalidCompanyProduct()
        {
            var companyProducts = Enumerable.Empty&lt;CompanyProductUrl&gt;().AsQueryable();
            
            var mockRepository = new Mock&lt;IEntityRepository&lt;CompanyProductUrl&gt;&gt;();
            mockRepository.Setup(r =&gt; r.FindBy(It.IsAny&lt;Expression&lt;Func&lt;CompanyProductUrl, bool&gt;&gt;&gt;())).Returns(companyProducts);
            
            var service = new CompanyProductService(mockRepository.Object);

            var result = await service.GetCompanyProductURLAsync(Guid.NewGuid(), &quot;wot&quot;, Guid.NewGuid());

            Assert.Null(result);
        }

However, when the test executes the call to the repository, I get the following error:

    The provider for the source IQueryable doesn&#39;t implement IAsyncQueryProvider. Only providers that implement IEntityQueryProvider can be used for Entity Framework asynchronous operations.

How can I properly mock the repository to get this to work?

I&#39;m trying to read the request body in the `OnActionExecuting` method, but I always get `null` for the body. 

    var request = context.HttpContext.Request;
    var stream = new StreamReader(request.Body);
    var body = stream.ReadToEnd();

I have tried to explicitly set the stream position to 0, but that also didn&#39;t work. Since this is ASP.NET Core, things are a little different I think. I can see all the samples here referring to old web API versions.

Is there any other way of doing this?

I&#39;ve heard of

* .Net Core
* .Net Portable
* .Net Standard
* .Net Compact
* Universal Windows Platform
* Portable Class Libraries

All of these were explained to me as _&quot;a subset of the full .Net that allows you to target multiple platforms&quot;_.  So my questions are

1. **What&#39;s the difference!?**
2. If I want to write a library that&#39;s usable to as large an audience as possible, **which one _(or more than one)_ of these do I need to use?**

---

_(My specific situation: I have [a library](https://github.com/BlueRaja/High-Speed-Priority-Queue-for-C-Sharp) that targets .Net 2.0, .Net 4.5, and UWP.  Targeting UWP required creating a new VS project and linking all the existing files, which is a huge pain.  Now someone is telling me it doesn&#39;t work for PCL, and from the sound of it I have to do it AGAIN for .Net Standard!?)_

Is there a way to test the exception messages with shouldly?

An example:

    public class MyException: Exception{
    }

The method  to be tested:

    public class ClassUnderTest
    {
        public void DoSomething() 
        {
            throw new MyException(&quot;Message&quot;);
        }
    }

I would usually test this in this way:

    [TestMethod]
    public void Test()
    {
        try
        {
            new ClassUnderTest().DoSomething();
            Assert.Fail(&quot;Exception not thrown&quot;);
        } catch(MyException me)
        {
            Assert.AreEqual(&quot;Message&quot;, me.Message);
        }catch(Exception e)
           Assert.Fail(&quot;Wrong exception thrown&quot;);
        }
    }

With shouldly I can now test if a exception is thrown:

    [TestMethod]
    public void TestWithShouldly()
    {
        Should.ThrowException&lt;MyException&gt;(() =&gt; new ClassUnderTest().DoSomething());
    }

But how can I test the message of the exception?

**Edit2**

I saw this [URL][1]. it suggests to create the nupkg using `dotnet.exe pack --no-build` whereas earlier I downloaded the `nuget.exe` from nuget.org to create the package.

I tried above command but then visual studio says

I could manually add references to all of the packages in the \packages folder but why isn&#39;t VS already checking there?
