How to access files within the wwwroot folder of a different project?

I have 2 projects that are needing to talk to one another. The first is a ASP.NET MVC project, that when in production, has a feature where the user can edit an html template that is stored in the wwwroot folder of the project.
The second project is a C# console app that grabs some user data from a database, and then uses that data to email surveys to users. The html template from the first project is needing to be grabbed by this console app so that it can be used in sending out these emails. I was hoping to use HtmlAgilityPack to grab the html email template from the first project when it is live, something along the lines of this:
var web = new HtmlWeb();
var document = web.Load("www.sitename.com/EmailTemplate");
string text = document.ParsedText;
But I'm open to other ideas that might work in this case. More or less I think I just need to figure out how to access static html files from within the wwwroot folder from a browser path, if that's possible. Oh and these two projects are going to be running on different servers, so local paths won't work. Thank you!

In large part thanks to ADyson's comments, the course of action that makes most sense in this situation is to create a small API within the MVC app, that fetches the html file, and the console app will call this API to retrieve the needed html.

I had a similar problem, and I did it by adding ~/ in the beginning of my static file addresses in my _Layout.cshtml.
My template files and photos were no longer loaded in the project but the layout was loaded. This way the files were also loaded

Set Default Directory for Lotus Notes File Upload Control

I have a lotus notes web form in which computer-illiterate customers will use to attach Excel files and submit them to our company. I am using a Lotus Notes File Upload Control to allow them to do this, however, I need to default this File Upload Control to a certain directory location. I have already created a C# application the customers will be using, which places all of these excel files in a certain directory location, hence the reason I need to focus this File Upload Control. Unfortunately, some of the customers are computer challenged enough to not know how to navigate to these files on their own. Is this possible at all?

I'm assuming the users will be visiting a web page with the File Upload control, yes? If I'm misunderstanding please let me know and I'll delete this answer.
The simple answer is it isn't possible. The problem is that the browser can't know anything about the file structure of the clients that visit the site, so a "default path" property doesn't really make sense. It would likely only work in very specific environments (which is maybe true in your case, but not across the web in general)

I would investigate using the Notes API to have the C# program handle the upload without involving the browser client use of the file upload control. I don't know enough Java to be sure, but perhaps that might also be an option -- basically writing your own custom upload control that only asks the user for the filename.
You may also be seriously underestimating the ability of the users to follow directions. If your page identifies which directory the file will be found in, I expect most users will be able to follow the directions and upload from the correct directory.
So, I'm sure that accomplishing what you want to accomplish is possible in Notes, just not as simply as adding a default directory to the File Upload Control.

AssetUrlSelector toolpart

What I need to do is quite simple although is causing me lots of trouble.
I need to create programmatically an AssetUrlSelector in a web part that selects a file in sharepoint 2010 and makes its path available to be used elsewhere.
So far I have managed to create the AssetUrlSelector and display the path on a textbox, however I cannot use this as every reference to it will be null.
Have you got any practical example?

Try the Document ID Service. In short this service generates IDs for documents (files) and generates an url with this ID so even if the file is moved the url stays valid and the service returns the document. This service might rely on search functionality unless you implement your custom search. Here is an article on how to configure OOB Doc IDs here. Also you can google further if you're interested.

What's the proper way to determine whether a certain URL sits within a certain directory?

I have a directory in my project that I want all calls to web pages within it and any sub directories to be diverted to another web site.
Eg.
If the directory is http://localhost/MyProject/MyDirectory, I want all URLs such as http://localhost/MyProject/MyDirectory/MyFile.aspx to be diverted to another web site.
I do not want to use IIS for this as there are some additional business rules relating to dates and stuff. There I was thinking of doing it in either my master page or in my global.cs file.
How though do I know whether the request is actually in the directory.
I was going to just go
if(Request.Url.AbsoluteUri.contains("http://localhost/MyProject/MyDirectory)
{
Response.Redirect("...")
}
But I feel that's not that good of a solution since may be in different domain names etc.

You could use Request.Url.AbsolutePath to get the path after the domain name.

Upload File to Website Using Save/As From Software Application

We all know that it is possible to "open" a Word document (or file from any arbitrary application) by clicking on a website link and then clicking the Open button.
I also know that, if I want to upload an application document to a web server, I must first save the document to my computer, and then go to an upload page, click a file/open button, find my saved file and upload it.
But is it possible to save a document to a website location or Url, effectively skipping the first save step and uploading the file to the web server through the Save dialog of the application, directly?
How would this be done in ASP.NET MVC?

It really depends on how complex you want to make it. This is pretty much what "web folders" offered (via WebDAV), but in general it creates more problems than it will ever fix. I don't recommend this approach.
Your best bet to make this simple is a dedicated client app - perhaps (although this is a dubious example) how Office talks to sharepoint. In a simpler example, you could create a silverlight out-of-browser application that saved via a web-service to a site using WCF or similar.

I think there is some creedence in what #Marc says. Personally I'd probably map a drive to the web site in question, if that's possible, and have a folder to upload to.
Then I'd have .Net check changes to the folder and take those files and import them into the repository, whatever that may be.
It's still an imperfect solution and I'm not sure there is a correct solution as yet.
I guess you could always write, and I can't believe I'm writing this, macros to save to the ftp location.

I'd guess you have a few choices, in no particular order:
Web service that the application can reference and upload through.
REST service (WCF or otherwise) that the application can POST to.
HttpHandler or MVC controller action that the application can POST to.
WebDAV directly to the server.
Number 3 sounds like it's closest to what you were looking for ("How would this be done in ASP.NET MVC?"). Scott Hanselman has a good article on handling file uploads in MVC on his blog.
When you implement the client, there's a little bit of a trick to that, too, since you can't just POST like usual; you have to post in multipart/form-data format. I posted a blog entry with some sample code on how to do that.
