Why is an old project name still being referenced in the temp files on Visual Studio

Question

I created and fully baked an MVC C# intranet PROJECT_A. Then I created and fully baked a WebForms C# intranet PROJECT_B.

Now I need to merge the two into a combo MVC/WebForms C# PROJECT_C.

I've done this and it seems to compile.

---

BUT... when I fire up the new PROJECT_C inside of my VS2013 Ultimate, I get an error on the resultant index page...

CS0246: The type or namespace name 'PROJECT_A' could not be found (are you missing a using directive or an assembly reference?)

In the Source Error section is this line that is (obviously) producing the error:

Line 1:    #pragma checksum "C:\...\PROJECT_C\Views\CONTROLLERNAME\Index.cshtml" "{ff1816ec-aa5e-4d10-87f7-6f4963833460}" "56225EBEFF70A747D10FB7D43A7A8EFCE86DAF72"

Line 33:   #line hidden...

I say "obviously" because PROJECT_A no longer exists in name. There is only PROJECT_C that I'm trying to hammer this round peg into!

The source file that is supposedly producing the error is listed as:

c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\14bee5fc\75cf6bf4\App_Web_index.cshtml.8117ffad.9pjm2azc.0.cs

---

In an effort to fix this I have done the following:

1. Cleared %temp% files
2. Cleared temp files from both c:\Windows\Microsoft.NET\Framework\ and c:\Windows\Microsoft.NET\Framework64\
3. Searched and replaced all instances of PROJECT_A (and instances of PROJECT_B) with PROJECT_C from within the code
4. Cleaned project/Solution
5. Checked namespaces in web.config and elsewhere
6. ... More that I can't think of

The error persists.

Updated progress:

I've noticed a possible discrepancy with the .net version. My target version is 4.5.1. However, I think that may be in the temp directory name only. You can see it in the source code pasted above. Here's from my web.config

<compilation debug="true" targetFramework="4.5.1">

I've, again, combed through my code looking for errant references to the old project and old classes and can't seem to find any. I've even looked through config.dll s in the bin/. I'm looking for namespace declarations and usings.

For the moment I've excluded the PROJECT_B directory from the main project just to keep it clean.

I really don't want to have to start fresh with a new MVC project as I've already done that. But I may have to.

I've been very careful to include as much information as possible. Let me know if I'm missing anything.

Thank you so much for the help! I'm on day two on this!

Answer 1

One more area to check is web.config file sitting under Views folder, if its excluded by Visual Studio then Find/Replace may not find it.

Change <namespaces> there as well.
