Why the gently caress did .NET MVC work perfectly fine yesterday then absolutely poo poo the bed when I rebuilt and published this morning? I fixed it by readding the references and setting copy local to true but it is not the first time this has happened.

There is probably something wrong with your project setup. I have never seen a case where "Setting copy local to true" is a meaningful step for a well-formed project, only cases where it can be sort of used to hide some deeper underlying issue.

I believe readding references fixed it, copy local was a panic move.

Trying to transition to visual studio 2015 and it's breaking on exceptions even if it's in a try/catch and even if I have all the exception types unchecked in the exception handler. What gives?

Is there a way in visual studio to check a project for all uses of any enums? I'm having serialization problems with them, but its not just one specific enum, and I have a few hundred of them to sort out (tool generated).

I'm assuming you mean this?

It's version 5.2.3.0

This is the properties window of the file that gets copied to the bin direction. The version doesn't seem to match, but I'm not sure what "version" it's referring to.

Are there any other projects in your solution that use it? What happens if you remove and readd the reference then rebuild?

We're in the planning phase of a project and I want to get a general opinion of our current plan.
1. User navigates to "upload" page
2. User uploads file
3. File is saved on the server (temporary files?)
4. Upon successful upload, user is redirected to a "review" page
5. File is run through some components to extract data, data is populated into the "review" page
6. User reviews/modified the extracted data on the review page, then submits
7. A record is created in a database from the data, and the file is saved to a new non-temporary location which is linked to from the record.
My biggest concern is how to deal with the file's persistence, making sure that it is properly cleaned up if the user backs out somewhere between steps 4 and 7 but also stays around for the entire process. Also, what would be the best way to make the review page recognize the file that was uploaded? I was thinking when the file was saved in step 3 to give it a GUID for a name, and pass that as a URL parameter to the review page when redirected but the filename will still be important for step 7.

Is there a way to make an XML serializer print like this:

pre:

<Contact>
  <FirstName>Bob</FirstName>
  <MiddleName></MiddleName>
  <LastName>Smith</LastName>
</Contact>

Instead of like this?:

pre:

<Contact>
  <FirstName>Bob</FirstName>
  <MiddleName />
  <LastName>Smith</LastName>
</Contact>

That doesn't involve painfully manually writing out the XML?

v That is (un)fortunately beyond the scope of my responsibility.

Is there any functional difference between these two?:

var x = DoThingAsync().Result;

var y = DoThingAsync();
y.Wait();
var x = y.Result;

I understand that both go against the whole point of the async methodology, this is just for a POC console app.

Something like this?:

pre:

        static T[] Foo<T>(params T[] c)
        {
            var ret = new List<T>();
            foreach (var obj in c) { ret.Add(obj); }
            return ret.ToArray();
        }

Seems kind of redundant to me but maybe I'm misunderstanding the goal

I'm lost and need some guidance. We're building an integration with a third party that uses JWTs to authenticate users. The tokens are signed using an x509 cert.
When I use the System.IdentityModel.Tokens.Jwt package to generate a token, it adds an x5t header to the token. We need this to be an x5c header instead, as the third party will not support x5t signed tokens. I've been struggling to find a way to change how the token is signed with no luck.

code:

var certBytes = System.IO.File.ReadAllBytes("certificate.pfx");
var cert = new System.Security.Cryptography.X509Certificates.X509Certificate2(certBytes, "******");

var claims = new List<Claim>
{
    new Claim("sub", "test"),
};

var x509SigningCredentials = new X509SigningCredentials(cert);

JwtSecurityToken securityToken = new JwtSecurityToken(
    claims: claims,
    notBefore: DateTime.UtcNow,
    expires: DateTime.UtcNow.AddMinutes(60),
    signingCredentials: x509SigningCredentials);

Console.WriteLine(securityToken.Header.X5t); // No option for x5c in this class

Yep, the third party engineer was very helpful and was able to provide a sample. So below is my x5c header token code, for posterity.

code:

var certBytes = System.IO.File.ReadAllBytes("certificate.pfx");
var cert = new System.Security.Cryptography.X509Certificates.X509Certificate2(certBytes, "******");

var claims = new List<Claim>
{
    new Claim("sub", "test"),
};

//Replaced with below
//var x509SigningCredentials = new X509SigningCredentials(cert);

                    RsaSecurityKey rsaSecurityKey = new RsaSecurityKey(cert.GetRSAPrivateKey());
                    var x509SigningCredentials = new SigningCredentials(rsaSecurityKey, SecurityAlgorithms.RsaSha512); ;

JwtSecurityToken securityToken = new JwtSecurityToken(
    claims: claims,
    notBefore: DateTime.UtcNow,
    expires: DateTime.UtcNow.AddMinutes(60),
    signingCredentials: x509SigningCredentials);

//This is the new x5c header stuff
                    X509Chain chain = new X509Chain();
                    chain.Build(cert);
                    List<string> x5cList = new List<string>();
                    foreach (var element in chain.ChainElements)
                    {
                        x5cList.Add(Convert.ToBase64String(element.Certificate.RawData));
                    }
                    securityToken.Header.Add("x5c", x5cList.ToArray());

I'm looking at options for extending a .net core program I've written so that users can create libraries that will be loaded up and imported.
Looking at options I see MEF is available in .net core now but I'm not finding a lot of information regarding security.
Where can I get info on restricting what actions are available in the loaded libraries' operations?

It's the latter, with the intent being distribution of plug-ins amongst the community that uses the program. Like what's a way to stop someone from making a plug-in that deletes (or attempts to) all the files in their C: drive?
Maybe I just need to have some sort of open source review and master build process instead of letting community members build their own plug-ins?

I think you can use char.IsLowSurrogate or IsHighSurrogate to detect this case.

There's a developer on our team that continues to use .NET Framework for all their work. I think they're intimidated by .NET Core or something. Any good resources you recommend that can be used to convince them to swap?

vvv Even though we are on the same team, we primarily work on separate projects. The requirement to have all projects on the same framework has not been mandated yet, but I suspect that will be happening soon, and want to have as little friction as possible when it does become reality.

Your team, a team of intellectuals: Have we considered doing a benchmark test of string concatenation methods to identify the most efficient way to generate our log files? We could increase performance by up to 4%!

            pos1 = searchstring.IndexOf(' ', searchstring.ToUpper().IndexOf(Tag.ToUpper()) + Tag.Length + 1);

My work falls into one of these categories
- little scripts or programs to shuffle data around
- backend data transformations, validations, restrictions from user submitted data
- building various integration APIs between our stuff and 3rd parties

There's SOME UI stuff occasionally but we let Microsoft's products do most of the heavy lifting on the front end
